[Pyusb-users] printing manufacturer, product and serial number strings

[Brendan S. (eTRIX) <Bre...@eT...>]

How do I print manufacturer, product and serialNumber strings using pyusb ??

I found the lsusb example here:

    http://wiki.erazor-zone.de/wiki:projects:python:pyusb:setup:examples:lsusb

but it didn't work :(


The dev.open().getString(1,30) caused a USB error.

    Traceback (most recent call last):
      File "lsusb.py", line 7, in <module>
        print "Bus %s Device %s: ID %04x:%04x %s" %
    (bus.dirname,dev.filename,dev.idVendor,dev.idProduct,dev.open().getString(1,30))
    usb.USBError: usb_control_msg(DeviceRequestTO): unknown error


I'm sure there is a simple solution, but this newbie is stuck :)

Thanks, Brendan.

Re: [Pyusb-users] support for OS X ??

[Brendan S. (eTRIX) <Bre...@eT...>]

Answering my own question here.

The answer is yes.
I ran usbenum.py on Mac OS X 10.5 and it gave me what the Vendor IDs and
Product IDs which is what I wanted :)

The readme indicates that it works on MSW and Linux too, so that's great
-- exactly what I need.

[Pyusb-users] support for OS X ??

[Brendan S. (eTRIX) <Bre...@eT...>]

I need to write a program on OS X that talks to a usb device that using
a serial protocol.

I have found PySerial which looks like a good cross-platform serial library.

I want to find the USB Vendor ID (VID) and Product ID (PID) of the
device before talking to it using the serial protocol.
I presume I can NOT do that with PySerial?
 I'm hoping that PyUSB will allow me to search for usb devices and find
the VID and PID.

Will PyUSB allow me to search for usb devices and find the VID and PID ???

Does PyUSB work on OS X, MSW and Linux ??

Thanks, Brendan.

Re: [Pyusb-users] Permissions problem

[<iku...@ya...>]

Just a guess,  but in my custom rules, I use the form         ATTRS{idVendor}=="0FC5", 
        ATTRS{idProduct}=="B080",  instead of your         ATTRS{idVendor}=="0x0FC5", 
        ATTRS{idProduct}=="0xB080".

No idea if that matters.




	 
	
	 
	



For further debugging information, try “udevmonitor
–environment” and looking at the output to /var/log/messages
after running “udevcontrol log_priority=debug” from the command
line (as root). Once you've launched these commands, you'll need to
exercise the scope – turn it on, attempt access, etc.
You can also check the permissions of the /dev/bus/usb/ entry...

I have my program working OK but need to run as sudo.
So now I am trying to get the program to run in user space but can't
seem to get it to work.

I am using Ubuntu 8.10 Intrepid

This is what I have done / tried so far.
1. Created a group called delcomusb
    $ sudo groupadd -g 1001 delcomusb
2  Created a file in /etc/udev/rules.d called 99-delcomusb.rules and
placed the following.  I tried both.
    # Delcom USB Device
    SUBSYSTEM=="usb_device", 
   
     ACTION=="add",
        ATTRS{idVendor}=="0x0FC5", 
        ATTRS{idProduct}=="0xB080", 
        GROUP="delcomusb", 
        MODE="0660"

    #BUS=="usb", SYSFS{idVendor}=="0x0fC5",
               SYSFS{idProduct}=="0xB080", MODE="0666"
3. Restarted udev
    $ sudo /etc/init.d/udev restart

4. Added user to have access to group: delcomusb
    System -> Administartor -> Users and Groups
    unlock user (and then entered password)
    select user ed
    click on "Manage Groups"
    click on delcomusb
    check ed and root for Group Member

But still get the error when I try and
 run
./DelcomUSBDevice.py

self.handle.claimInterface(self.intf) # Interface 0   
usb.USBError: could not claim interface 0: Operation not permitted

But everything works fine with sudo.

Is there some step I missed?

Thanks
ed

My syntax is different from yours (on a single line):

SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", SYSFS{idvendor}=="08d3",
SYSFS{idProduct}=="0001", MODE="0666"

Which works for me.

Re: [Pyusb-users] Release Interface and Detach Kernel Questions

[Thomas R. <tre...@de...>]

Ed,
what happens if you just catch the exception from your detach command?
Eg.
    try:
        self.handle.detachKernelDriver(0)
    except usb.USBError, err:
        print >> sys.stderr, err

Otherwise, if the kernel driver is already detached, you will not claim
the interface.
Regards,
-Thomas

[Pyusb-users] Release Interface and Detach Kernel Questions

[ed <ene...@co...>]

When I first run my program everything is OK.  That is I can detach the
        kernel interface and then claim the interface and then release
        the
        interface.
        
        TERMINAL OUTPUT
        ed@ed-desktop:~/Desktop$ sudo ./DelcomUSBDevice.py 
        Found Delcom Device
        Claiming interface
        Manufacturer:  Delcom Products Inc.
        Product:  USB IO Controller 
        Bytes written %s 8
        Sleep 2 seconds
        close done
        
        But if I run the program a 2nd time or more I get two errors.
        1. could not detach kernel driver from interface 0: No data
        available
        2. No interface claimed

[Pyusb-users] Source code repository migration

[Wander L. <wan...@gm...>]

Dear all,

PyUSB source code has been moved from Berlios cvs to SourceForge svn.

branches/0.x - 0.x version source code.
trunk - PyUSB 1.x version source code.

Anyone interested in getting the lastest source code should refer to
sourceforge svn from now.

Thank you all,
Wander Lairson Costa

Re: [Pyusb-users] New to pyusb & 'exclusive access' Problems

[Wander L. <wan...@gm...>]

There is an error on readme file (by the way, it reminds me that I
need to check if I fixed it before release the new version): according
to USB specs, setConfiguration(0) will cause the device to enter in a
not configured state, configuration index should be at least 1, so,
setConfiguration(1) probably is correct for your device.

Re: [Pyusb-users] New to pyusb & 'exclusive access' Problems

[Sarah M. <iku...@ya...>]

I haven't had much problem with Set_Configuration, partially because (IRC), the actual set_configuration command isn't required for most devices.  (Most only have one configuration, which is set by default.)

I also haven't used Mac, but here's what I've got right off:

It sounds like you've got a permissions error.  A couple things to check for that, extrapolating from SuSe Linux:

Make sure the device is being attached with a user or group corresponding to your user.  If not, try running the code as root.  Assuming that you can access it as root and not as user, you almost definitely have a basic permissions error.

Unfortunately, as I found out last year, "basic permissions error" covers a lot of territory.  On my system, I had to 1)  Create a "usb" group; 2) Add the necessary users to the "usb" group; 3)  Make sure there was an appropriate rule for my device in /etc/udev/rules.d (Check the linux-hotplug group for details there.);  4)  Make sure that rule used ATTRS to access the device instead of SYSFS (which was my initial guess);  5)  Make sure the devices I was trying to reach were configured to obey the USB port rather than try to control it; and 6) Put a USB hub between the PC and the device.  No idea why that should matter, but for some reason, it improved communication substantially.

Anyhow,  below is the text from my last post on the libusb-devel and linux-hotplug groups.  Since pyusb is (mostly) a wrapper for libusb functions and linux-hotplug handles most of the permissions aspects of talking to USB devices, those groups will likely be good places for follow-up questions.


Cc: "libusb-devel" <lib...@li...>, lin...@vg...
Date: Monday, January 5, 2009, 9:58 AM

Changing SYSFS -> ATTRS in 55-libsane.rules worked.  Thanks

For the record, the command sequence I use (in pyusb) is:

import usb        #sets up libusb
...
allBus=usb.busses()   #read in a list of available USB busses
...
bus=allBus[bIndex]       #focus on bus number bIndex
dev=bus.devices[dIndex]   #focus on device number dIndex on that bus
hand=dev.open()            #open that device and return the DeviceHandle
                #read the device serial number as a string
                #prepend 'USB' to distinguish this from RS-232 equipment
                #on the same system
thisSerNum='USB'+hand.getString(dev.iSerialNumber, USB_SHORT_BUFF)   
...

Ellipsis marks omitted code which sets up variables and is not directly related to the usb managment. 

The code fails at the hand.getString() call (with SYSFS in the .rules file).

This code is part of a device-identification loop, and so there is no claimInterface() command.  Device-descriptor queries like the above are necessary to determine which interfaces are available for claiming.

Thanks for your help.

[Pyusb-users] New to pyusb & 'exclusive access' Problems

[George W. <geo...@bi...>]

Gidday
I installed libusb 0.1.12 and pyusb 0.4.1 on Mac OSX 10.5.6
I get samples/usbenum.py to run OK
but Isusb.py will only run if I remove the
dev.open().getString(1, 30)
item.
Following the interactive steps the Readme I get to the step  
'handle.setConfiguration(0)'
which produces the error
 >>> import usb
 >>> bus = usb.busses()
 >>> dev = bus[0].devices[0]
 >>> handle = dev.open()
 >>> handle.setConfiguration(0)
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
usb.USBError: usb_set_configuration(SetConfiguration): device not  
opened for exclusive access
 >>>

I followed some threads on this list relating to the exclusive access  
error  (in darwin.c?) but have been unable to discover if someone has  
found a solution.
What's the latest on this?

[Pyusb-users] Memory leak in usb.busses()?

[Sarah M. <iku...@ya...>]

I seem to have discovered a memory leak in usb.busses(), though I haven't yet tracked it down in detail.  Procedure to expose it:

open two terminal windows.  In one, start up a watch with ps:
> watch -d -n 0.1 'ps -A H -o spid,%cpu,rsz,nlwp,start,eip,stat,cmd | grep python'

The third column is the amount of memory used by each listed application.  (In kB, I believe.)

In the other, start up Python:  (The numbers left of the ">" are my results for memory used by python before the line executes.)
0      > python
4940   >>> import usb
5040   >>> usb.busses()
5168   >>> usb.busses()
5216   >>> usb.busses()
5220   >>> usb.busses()
5220   >>> a=usb.busses()
5228   >>> a=usb.busses()
5272   >>> a=usb.busses()
5276   >>> a=usb.busses()
5276   >>> usb.busses()
5276   >>> usb.busses()
5276   >>> b=usb.busses()
5328   >>> a=usb.busses()
5328   >>> a=usb.busses()
5328   >>> usb.busses()
5328   >>> b=usb.busses()
5328   >>>

I dunno - it seems to stabilize after several calls, and seems to depend on the assignment statement - which may have more to do with Python itself than pyusb - but I don't get this behavior with simple lists...  and forcing a call to the garbage-collection routine doesn't recover the memory.

Anyone seen this before?  Anyone know if it's a feature of pyusb or python?

Some Context:
Python 2.6 (r26:66714, Feb  3 2009, 20:49:49)
[GCC 4.3.2 [gcc-4_3-branch revision 141291]] on linux2
OS: Linux 2.6.27.19-3.2-default x86_64
openSUSE 11.1 (x86_64)
KDE 4.1.3 "release 4.9"

It's probably not a big deal, but I'm using Python code to manage a number of usb devices which occasionally get hot-swapped while I'm trying to talk to 'em.  To make sure I have the comm. set up right I have to call usb.busses() on a fairly regular basis.  I'm leaking memory in several places, with the result that the code slows substantially over the course of a day.  This is just the first leak I've located.

Thanks

[Pyusb-users] pyusb and pyserial

[Joe A. <joe...@gm...>]

Hello All,

I hope this is the right place for a pyusb user question.  If not, I
apologize (and if you could direct me to an appropriate forum I'd be
obliged).

I am trying to control a thorlabs computer-controlled rotation stage.
The device contains an FT232BM peripheral chip, and can be controlled
with the pyserial package.  However, to figure out which device to
open with pyserial, I check dmesg and see that it's been mounted on
/dev/ttyUSB0.  Then I open pyserial and am about my business.

I'd like to be able to search for all motion controllers connected to
my computer.  I *can* do that with pyusb.  The following code finds
all the devices, and by manufacturer and serial number I can find out
exactly which device is which:


for bus in usb.busses():
   for dev in bus.devices:
      print "Bus %s Device %s: ID %04x:%04x" %
(bus.dirname,dev.filename,dev.idVendor,dev.idProduct)
      h = dev.open()
      print "Manufacturer: %s" % (h.getString(dev.iManufacturer,30))
      print "Product: %s" % (h.getString(dev.iProduct,30))
      print "SerialNumber: %s" % (h.getString(dev.iSerialNumber,30))


My question is:  once I know the usb bus and device numbers, is there
a way to learn that that bus/device combination maps to /dev/ttyUSB0?

Re: [Pyusb-users] pyusb 0.4.1-2.fc10.i386 does not detect Lego NXT brick ...

[Michael W. <mic...@sp...>]

The following (http://nxt.ivorycity.com/) seems to work:
As root, create /etc/udev/rules.d/70-lego.rules containing:

  # Lego NXT 
  BUS=="usb", SYSFS{idVendor}=="0694", MODE="0666"

(1st two operators are comparisons "==", 3rd is assignment "=")
Hope this helps someone else.
Thanks for the bandwidth.

Re: [Pyusb-users] pyusb 0.4.1-2.fc10.i386 does not detect Lego NXT brick ...

[Michael W. <mic...@sp...>]

Seems that I'm having a permissions/sucurity problem. 
When I run usbenum as root it finds the device.  
When I run usbenum as a normal user, it does not.
Perhaps I need to add a line to /etc/fstab or something?
Anyone know what to do here?

Thanks,

- Mike

[Pyusb-users] Install instructions for the mac

[Phil H. <ph...@ha...>]

Hello,

I need to test my driver on the Mac OSX.  Does anybody have any instructions on
what to install to get PyUSB up and running?

Regards
Phil Hannent

Re: [Pyusb-users] pyusb 0.4.1-2.fc10.i386 does not detect Lego NXT brick ...

[Wander L. <wan...@gm...>]

Actually I don't know if lsusb uses libusb or usbdevfs directly..
Later I will download the source code and take a look...

Re: [Pyusb-users] pyusb 0.4.1-2.fc10.i386 does not detect Lego NXT brick ...

[Wander L. <wan...@gm...>]

Please, try it with lsusb command. If it works, it maybe a PyUSB or
libusb issue. Would you mind trying to build a little C program T
check it? It the C program works, it is probably a PyUSB issue. In
this case, please, open a bug request in SF, informing the PyUSB and
libusb versions.

Best regards,
Wander

[Pyusb-users] pyusb 0.4.1-2.fc10.i386 does not detect Lego NXT brick ...

[Michael W. <mic...@sp...>]

If anyone can give me a clue as to how to fix this, I'd sure appreciate
it.  When I cat /proc/bus/usb/devices, the NXT shows up (on bus 4) with
the expected vendor (0x0694) and product (0x0002) numbers, but not when
I run a modified usbenum program.

The data follows.

Thanks,
- Mike

[Pyusb-users] Replug device?

[Alan A. <fru...@gm...>]

Hi,

I have a IR Remote control that I'm writing a program for. I've run into a  
problem however.
I handle the error that occurs if you unplug the device while the program  
is trying to read from, this drops the program into a loop waiting for the  
device to be replugged in. When the device is plugged in again, the  
program finds it but then crashes usually with this error:

usb.USBError
could not release intf 1: No such device

The program works properly if the device is unplugged initially, and then  
plugged in after the program has started.

I can post sections of code as requested, but it seems I'm doing things  
the same as most others form the code I've seen.

Anyone have any ideas?

Cheers,
Alan

[Wander L. <wan...@gm...>]

Hmmmm, I am sorry, I forgot, libusb under Windows is another project:
libusb-win32.sf.net. I guess they will
be more helpful regarding to this issue...

Re: [Pyusb-users] libusb-win32 & pyusb-0.4.1 for cygwin

[David P. C. <dav...@gm...>]

Hello,

I did not get any answer from the libusb mailing list.

Can you please try this command and let me know what you get?
/usr/bin/cygcheck `/usr/bin/cygpath -w -a
/usr/lib/python2.5/site-packages/usb.dll`

I get the following:
$ /usr/bin/cygcheck `/usr/bin/cygpath -w -a
/usr/lib/python2.5/site-packages/usb.dll`
C:\cygwin\lib\python2.5\site-packages\usb.dll
  C:\cygwin\bin\cygwin1.dll
    C:\WINDOWS\system32\ADVAPI32.DLL
      C:\WINDOWS\system32\KERNEL32.dll
        C:\WINDOWS\system32\ntdll.dll
      C:\WINDOWS\system32\RPCRT4.dll
        C:\WINDOWS\system32\Secur32.dll
Error: could not find cygusb0.dll
  C:\cygwin\bin\libpython2.5.dll
