[Pyusb-users] Newbie Question

[Christopher M. <chr...@bn...>]

Hey everyone,

I'm trying to write my first program with pyUSB.  I have already figured
out how to identify my device, open it, add it to a handle, close it and
claim it's interface.

Here's my situation:

The kernel recognizes my device ( a linksys cit200) as a device already
and it actually shows up as a plughw device.  The problem is the device is
not "activated"  My question is, do I have to claimInterface this device
to send/receive signals to it?  For now, I just want to see if I can
"enable/activate" it, so the mic/speaker will work on the thing.

Right now, in order for me to claim the interface, I have to
detachKernelDriver each interface (there are 4 of them, 3 alsa/sound, 1
hid), then setConfiguration, then claimInterface.  In doing so, I lose ...
it showing up as those devices.


Example Code:
---------------------------------------------
import usb

# linksys CIT200 Device Info
vendor_id = 5041
product_id = 29

buses = usb.busses()

for bus in buses :
for device in bus.devices :
  if device.idVendor == vendor_id :
    if device.idProduct == product_id :
  # found the CIT200
  linksys = device

# open device
handle = linksys.open()


# setup interface and configs ... there are 4 interfaces for this device...
config = linksys.configurations[0]
interface = config.interfaces[0][0]

# detach kernel drivers
handle.detachKernelDriver(0)
handle.detachKernelDriver(1)
handle.detachKernelDriver(2)
handle.detachKernelDriver(3)

# set configuration and claim interface(s?)
handle.setConfiguration(config)
handle.claimInterface(interface)
handle.setAltInterface(interface)
---------------------------------------------


Any help would be appreciated.  I will probably have a few more questions
to follow :)

Thanks

[Pyusb-users] Enquiry about PyUSB

[Abhishek W. <abh...@gm...>]

Hi..
I'm trying to make a Software USB based on AVR309 application note available
at www.atmel.com/dyn/resources/prod_documents/doc2556.pdf
So what basically i'm doing is programming a ATTINY-44 to do functions of a
USB-driver and when connected to USB port, should be automatically detected
by the computer.
Now i'm also making a GUI using Tkinter in Python to read data from the
microcontroller & to write in it.
I was thinking of using pyUSB for this purpose.
but i'm unable to understand how to read and write from a USB device using
pyUSB.
Please help me in any way in this regard.
Thank U.

Re: [Pyusb-users] Correctness of this code?

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

Actually the documentation is wrong. The results what you are getting
are ok. The number of bytes transfered is only returned when is
executed a control OUT transfer. In control IN transfers, the function
returns the data read.

I'll fix that in the next release.

Would mind opening a bug report at the project page?

Thanks,
Wander

[Pyusb-users] Correctness of this code?

[<lin...@co...>]

Keep in mind that I am new to this USB and hardware hacking stuff. 

Alright I am writing this little python application to pull the firmware from a device using the Cypress EzUSB Fx2 chip. Snazzy little thing.

To do that you generally use fxload to load the Cypress developer kit-supplied Vend_ax.hex code. It loads into ram, resets the cpu, and then you can get access to some vendor commands to read and write to the eeprom. 

The reason I am doing this is because I need to have a way to verify the firmware on any random device on of this type. This is due to some sticky certification issues that I won't bother you with. I like python so this seems the way to go.

Once you get the vend stuff loaded then you use control messages to send a request and your given a hunk of code. 

So.. it's the syntax of the controlmsg function that I have a question about. I have everything working right now and the script is working and all that, I just want to make sure that this behavior is 'correct'. Because once I say this is 'finished' it'll be very difficult to change the script.

So a truncated version of the script looks like this:


buses = usb.busses()
for bus in buses:
    for device in bus.devices:
        if device.idVendor == vend_id and device.idProduct == prod_id:
            mooCow = device

mooCowHandler = moocow.open()

results = mooCowHandler.controlMsg(0xc0, 0xa2, data, address, 0xBEEF, 10000)


Ok.. so it works and it makes me very happy with good feelings and all that.

But my question is this:

According to the documentation I would expect that the output from the command would be put into 'data' and the 'results' would be a return value for number of bytes written.

 |  controlMsg(...)
 |      controlMsg(requestType, request, buffer, value=0, index=0, timeout=100) -> bytesWritten|buffer
 |      
 |      Performs a control request to the default control pipe on a device.
 |      Arguments:
 |              requestType: specifies the direction of data flow, the type
 |                           of request, and the recipient.
 |              request: specifies the request.
 |              buffer: if the transfer is a write transfer, buffer is a sequence 
 |                      with the transfer data, otherwise, buffer is the number of
 |                      bytes to read.
 |              value: specific information to pass to the device. (default: 0)
 |              index: specific information to pass to the device. (default: 0)
 |              timeout: operation timeout in miliseconds. (default: 100)
 |      Returns the number of bytes written.


However with my code it does something quite differently. 

The 'results' end up being a tuple of returned values! Not the number of bytes. And the 'data' needs to be a number that tells it how many bytes I want returned from the command!

This is quite a bit different then what I expect after reading the docs and thus is why I am worried.

When I try to make the 'data' be a tuple or a list of objects or whatnot then It'll end up being unmodified when I run the script, but the results ends up being the number of items I put in the data list. I am confused.

So I want to make sure that this is the correct behavior for this function. (for it to return a tuple of the results) I am not a stickler for 'correctitude' or anything like that, but I want to make sure that this behavior isn't a 'bug' that is going to get 'fixed' and break my script in the distant future.

I am using python-usb package version 0.4.1-4  provided by Debian Testing/Unstable.

Thank you!!

[Pyusb-users] Program doesn't seem to be writing

[Bob C. <bc...@co...>]

Hi,

I'm trying to reverse engineer my iClicker base unit and create a Linux 
driver.  Everything seems to be going OK except:

    print handle.controlMsg(reqType,usb.REQ_SET_CONFIGURATION,0x40,0x200,0)
    print "written? ",handle.interruptWrite(0x83,dataOut,1000)

The sniffer I am using shows a read rather than a write.

I'm stuck.  I don't know whether my sniffer is lying to me or if I have 
a mistake in my code or if I haven't figured out the device's command 
structure.
_________________________________________________________________________________________________________________
A couple of comments:

I'm including the code, the program output and the sniffs as attachments 
so the body of the email doesn't get a mile long.

The controlMsg seems a little un-standard according to the usb spec but 
I'm trying to create a setup packet that I sniffed from the Windows 
app.:  21 09 00 02 00 00 40 00  The output I get in Linux (using a 
different sniffer) is: 21 09 0200 0000 0040.  I'm not absolutely sure 
but it looks like the Windows sniffer reverses high and low bytes for 
the two byte variables.  (40 should be in the low byte not the high byte.)

If I omit the controlMsg, the result is:  USB Error: No Error

The Linux sniffer is:  sudo cat /sys/kernel/debug/usbmon/1u > /tmp/1.mon.out

The Windows sniffer is: *SniffUSB.exe 
*(http://benoit.papillault.free.fr/usbsnoop/doc.php.en)


Thanks,

Re: [Pyusb-users] pyUSB error

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

Hi,

By "NAKed" and "ACKed" endpoints I mean states of the endpoints. This
generally is represented by some control register bit flags for each
endpoint. Please, refer to the datasheet of your microcontroller. If
it's not take time more, maybe the endpoint is stalled too.

[Pyusb-users] PyUSB win32 binaries

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

Hi there,

It's available in the project page the win32 installer package.

Thanks,
Wander.

Re: [Pyusb-users] pyUSB error

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

No problem. Well, seems that o endpoint is "NAKed", try a longer
timeout and see if it function takes more time to return. If so,
review your firmware code to discover if the endpoint is "ACKed" in
the enumeration process...

Re: [Pyusb-users] pyUSB error

[Gabriel <gb...@gm...>]

I'm sorry. I didn't see the field "to" of my e-mail...
I'm making a development with a PIC 18f2455... It has embedded usb.
The PIC's firmware is a loop that read all time and put the sent value into
PORT B.
The developers of the firmware maked the firmware in basic and they maked a
program in basic to send values.
Now, I want to use pyusb. But I obtain this error... I have only send a
byte. I find the device with pyusb but I can't send the byte...

Thank you very much...

                       break
if dev == None:
    print 'ProtoTermociclador device not found'
else:
    handle = dev.open()
    handle.interruptWrite(0x01,'\x00')

I run the code with sudo python mycode.py and I get an error.

[Pyusb-users] Using pyusb

[Mike H. <me...@mi...>]

Hi all,

I'm very new to this list, so hello all!
I'm just starting out using python, my background is lamp.

I have a Prolific Technologies bridged usb cable that I wish to talk to
using pyusb and libusb, I've tried following examples and compiling my
own code but I'm really struggling getting it to work.

I'm trying to send a sequence of letters to the cable, for them to
reappear on the other side. I've been trying to use bulkWrite and
bulkRead methods but I'm not sure I'm using them right. There's also
controlMethod, but I'm not sure what that is used for.

Can anyone help get me started, I'm concerned mostly with the
communication, I reckon I could actually get somewhere if I can just
nail the first bit, here's my code so far:

* Cheers in advance, Mike.

Googling it. Very much not familiar with the detailed specs, but
willing to learn. :-)

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

Do a search for the USB and USBTMC specifications - you'll be doing byte-level manipulations to set up and keep track of the transfers.  pyusb great works, but assumes you're familiar with the detailed specs.

Wander Lairson <wan...@gm...> wrote: Hi Gilles,

These parameters from controlMsg map directly from libusb parameters,
which maps directly from USB control transfer specifications. To
resume, most of these parameters go into specific fields into control
packet. If your device supports control transfers, should exist some
documention how it interprets each field...

Hi Wander - awesome, thank you. So the question is basically how to
access my device via USB control transfer. The device actually has an
internal USB-to-serial converter, hopefully that's no obstacle though.

Hi Gilles,

These parameters from controlMsg map directly from libusb parameters,
which maps directly from USB control transfer specifications. To
resume, most of these parameters go into specific fields into control
packet. If your device supports control transfers, should exist some
documention how it interprets each field...

[Pyusb-users] control message format?

[Giles B. <gi...@gm...>]

Hi - I've got PyUSB up and running and giving me basic data on the
device I want to read and write to. What I have from the manufacturer
is a protocol, basically a list of sequences of bytecodes. For
instance, to turn the device on, you need to send:

02H (which I believe means hex, so 0x02)
three 0x00 bytes
192 0x00 bytes
and finally a 0x02 checksum byte

I'm using this really cool USB missile launcher control code to work from:

http://blog.taragana.com/index.php/archive/how-to-control-usb-missile-launcher-on-linux/

and that code contains some controlMsg calls.

what I can't figure out is the arguments for controlMsg and how they
map to to the sequence of bytes I need to transmit. I have this from
the pydoc:

controlMsg(requestType, request, buffer, value=0, index=0, timeout=100)

are requestType and request constants within PyUSB? do I need to
separate out the different pieces of my byte sequence or should they
all just go in buffer? how do I choose whether my bytes go in buffer
or value?

[Pyusb-users] detach kernel driver error No data available

[betoman <be...@gm...>]

hi, I have an IR interface with serial port and usb adapter... i have no
serial port so im tryiing to use it with usb and python...
my problem is that i cannot do anything xD
I tried do this:

*import usb
for bus in usb.busses():
     for dev in bus.devices:
          if dev.idVendor==0x4fc and dev.idProduct==0x201: IR=dev


>>> IR.open().detachKernelDriver(IR.configurations[0].interfaces[0][0])
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
usb.USBError: could not detach kernel driver from interface 0: No data
available

>>> a.open().claimInterface(a.configurations[0].interfaces[0][0])
>>>

>>> a.open().bulkRead(a.configurations
[0].interfaces[0][0].endpoints[0].address,30)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
usb.USBError: could not detach kernel driver from interface 0: No data
available*

after bulkRead dmesg throws

*usb 1-1: usbfs: process 4886 (python) did not claim interface 0 before use*

and I dont know what i can do

mi kernel : 2.6.22

im using Python 2.4.4


the IR interface is kosmos if anyone knows it...
thanks

Re: [Pyusb-users] Trouble Installing, Mac OS X 10.4.10

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

Seems that libusb header is not in the include path of the gcc. Try to
locate where
libusb installation has put it on... After that, you can modify the
setup.py script to
add the header path to gcc...

[Pyusb-users] Trouble Installing, Mac OS X 10.4.10

[John F. <joh...@co...>]

Hi Group,

It looks like it might take a little while for this message to get  
seen, but here goes. I am trying to install pyUSB on my MacBook Pro.  
It is therefor an Intel machine. OS X 10.4.10 ( I am afraid to jump  
right in to Leopard...). I have installed libusb first. It did not  
pass all the tests in make test, but I proceeded blithely to attempt  
the install of pyUSB. Here is the terminal window result:

hello guys,
                    i am really new to usb programming so plz help
i am trying to access kingsun dazzle irda via pyusb



import usb
from struct import *

vendor_id= 0x07d0
product_id= 0x4100
supported_speeds =
[2400,9600,19200,38400,57600,115200,576000,1152000,4000000,0]
bRequestType= 0x21
bRequest  =   0x09
wValue    =   0x0200
wIndex    =   0x0001
wLength   =   0x0008
hello=[]
buffer = pack('lhh',115200,0x03,0)

def find_dazzle():
    buses = usb.busses()
    for bus in buses :
        for device in bus.devices :
            if device.idVendor == vendor_id :
                            if device.idProduct == product_id :
                                print "found ksdazzle"
                    return device

if __name__=="__main__":
    device=find_dazzle()
    for alt in device.configurations[0].interfaces[0]:
        for ep in alt.endpoints:
            print "endpoint:",hex(ep.address)
    handle=device.open()
    handle.reset()
    handle.setConfiguration(1)
    handle.claimInterface(0)
    r=handle.controlMsg(bRequestType,bRequest,buffer,wValue,wIndex,10000)
    #while 1:
    #    r=handle.interruptRead(1,2048,10000)
    #    print r
    handle.releaseInterface()


while running the above program ie while sending that contol message i
receive the following error

found ksdazzle
endpoint: 0x81
endpoint: 0x2
Traceback (most recent call last):
  File "a.py", line 33, in ?
    r=handle.controlMsg(bRequestType,bRequest,buffer,wValue,wIndex,10000)
usb.USBError: error sending control message: No such file or directory

my demsg shows this

usb 1-1: reset low speed USB device using ohci_hcd and address 2
usb 1-1: usbfs: process 16850 (python) did not claim interface 1 before use

plz helppppppppp
