No, I can't test it since I have no Vista system to test on.

When do you get this error? When you install it or when you run your app?

[Libusb-win32-devel] usb_bulk_read error

[Gavin B. <gb...@ax...>]

Guys,

I have been writing firmware and PC end stubs for a USB-based 
development board. It has come to my attention that there may be a 
problem with the firmware that I have written.

I receive the following error message upon calling usb_bulk_read:

Bulk Read Vendor Request failed (-12).
usb_submit_async: error: Not enough storage is available to process this 
command

Should I take this on face value, or is there something deeper going on 
here? How should I modify my firmware in lieu of this fact? I would be 
grateful if someone could shed some light on this situation.

Thank you,
	   Gavin Brewer.

[Libusb-win32-devel] libusb-win32 plug events

[Joseph D. <jd...@ho...>]

I'm not sure if this is the correct place to ask this or not, but how
do I detect when a usb device is plugged in?  I've successfully created
an .inf file to bind my device to the libusb-win32 driver.  I also have
an application that uses the libusb dll to interact with my device.
I'm planning on turning that application into a service, but I need to
execute some code whenever a device is plugged in.  How can I detect
when someone plugs in one of my devices?  Or is there a better way to
organize this?

-Joseph

Hello,
you have test this? The Filter driver not work here (Vista 32Bit), I
get always an error
"C:\Program Files\LibUSB-Win32\bin\libusb0.dll
This file is not design to work with windows or contain an error"
(translated text)

Or are they any special thing that I must do when I install it in
Vista?
(I have install it as admin)

The current version should work on 32bit Vista without any problems,
even the filter driver, but NOT on 64bit Vista.

What I’m working on right now is a new version of the DLL that will
use Vista's built-in winusb.sys driver instead of libusb's own kernel
driver. Most of the features are already working.

The problem with winusb.sys is that it's not possible to use it as a
filter driver. So libusb 'filter driver mode' might not be supported in
the future any more.

I hope I can manage to release a beta version within the next
weeks.

Is there somewhere maybe a pre-beta which not work completly, but can
included in a C++ project with
#pragma comment( lib, "libusb.lib" )
in my project?
(comment out all the libusb calls line with #ifdef, or something
similiar is not a good idea... ;) )

You don't have to switch!
The next release will support Vista. I'm currently working on a new
version of the DLL that will use winusb.sys on Vista instead of libusb-win=
32's
own kernel driver.

Hi Peter,

Sorry I found no thread about Vista here or in the general group or I
get no response.

Or must I really switch to WinUSB and give up to use LibUsb any longer?

I am not sure, you get it to work, or not?
When I try do install the snapshot file from
http://sourceforge.net/project/showfiles.php?group_id=78138 i get only
an error message about libusb0.dll, what should I do now? Must this DLL
resist in system32 or what would happen when I move this file to the
application folder from the applicatin which use it?

I hope you have any solution how to install the filter driver in Vista
32 bit.

Download the DDK from Microsoft's web site and take a look

[Libusb-win32-devel] No devices found

[<ww...@se...>]

Hi all, 
 
I have a small program to show list of connected usb devices. It works fine under Linux, but when I port it into libusb-win32, it doesn't - it doesn't detect any device! And I really don't know why :(  
 
Attached example - testlibusb.c doesn't detect any device too. 
 
I'm using WinXP, libusb-win32-snapshot-20060827. 
 
Here is my code: 
 
#include <stdio.h> 
#include "usb.h" 
 
int print_device(struct usb_device *dev) 
{ 
usb_dev_handle *udev; 
int ret, i; 
 
printf("dev:%i\n", dev); 
udev = usb_open(dev); 
printf("udev:%i", udev); 
 
printf("#%x - %x\n", dev->descriptor.idVendor, dev->descriptor.idProduct); 
 
for (i = 0; i < dev->num_children; i++) 
print_device(dev->children[i]); 
 
return 0; 
} 
 
int main(int argc, char *argv[]) 
{ 
struct usb_bus *bus; 
 
usb_init(); 
usb_set_debug(0); 
 
usb_find_busses(); 
usb_find_devices(); 
 
for (bus = usb_get_busses(); bus; bus = bus->next) { 
struct usb_device *dev; 
printf("bus:%i\n", bus); 
printf("bus->devices:%i\n", bus->devices); 
for (dev = bus->devices; dev; dev = dev->next) { 
print_device(dev); 
} 
} 
 
return 0; 
} 

output:
bus:4846846
bus->devices:0
 
Can anyone help me, please... ? I've installed libusb0.dll into program's directory and then into system32, but it still doesn't work. Thanx in advance.

Try usbmon. You need to recompile your kernel (enable debugfs
and build usbmon as module). I do not think it is as mature as the
USB sniffers under Windows.

There are some documentations about usbmon.
http://people.redhat.com/zaitcev/linux/index.html

>From Linux 2.19.1 Documentations/usb/usbmon.txt:
*******************************
* Introduction

The name "usbmon" in lowercase refers to a facility in kernel which is
used to collect traces of I/O on the USB bus. This function is analogous
to a packet socket used by network monitoring tools such as tcpdump(1)
or Ethereal. Similarly, it is expected that a tool such as usbdump or
USBMon (with uppercase letters) is used to examine raw traces produced
by usbmon.

The usbmon reports requests made by peripheral-specific drivers to Host
Controller Drivers (HCD). So, if HCD is buggy, the traces reported by
usbmon may not correspond to bus transactions precisely. This is the same
situation as with tcpdump.
...
* Raw binary format and API

TBD

[linuxguy <lin...@gm...>]

Can someone recommend a good USB sniffer application for Linux ?
Something like ethereal (wireshark now...) except for USB instead of
Ethernet.

Thanks.

Re: [Libusb-win32-devel] cant un-install libusbw32

[Stephan M. <ste...@we...>]

Libusb does not take over the USB stack. Libusb's kernel driver is just
a normal device driver, nothing special.=20
Switching between different drivers is usually done through the device man=
ager:

* open the device manager
* right-click in your device and select "update driver"
* a new window will open, select "No, not this time"
* select "Install from a list of specific location (Advanced)"
* select "Don't search. I will choose the driver to install"
* select the "Have Disk" button and open the driver's .inf file you want t=
o install
* You will now see a list of compatible hardware. Select the driver you wa=
nt to install
* finish the install

Libusb has completely taken over my USB driver stack.
I cannot run my USB device with the manufacturers driver.
Everytime I install the device, I am prompted for the path for the

How do I get libusb off of my syrm?

That is a great find.  Thank you Andreas.  And I was starting to like

It's tested on Linux and Windows, but should work on every OS.

[Libusb-win32-devel] Using libusb with Java on Windows.

[linuxguy <lin...@gm...>]

I've got an Java application that desperately needs USB functionality.
There are no Java USB objects that I am aware of.  A libusb type object
in Java would be ideal.

Has anyone used swig to generate a java object from libusb ?

I don't have access to a Windows development system.  I develop under
Linux.  If I generated Java objects for libusb under Linux and got it to
work, would someone run swig and a C compiler under Windows for me ?

Thanks.
