Hi
I just wanted to add that I have installed libusb-win32 if the
version of the lib matters!

Hi Wander,
So I think it's a "ValueError: No backend available" error.
I have the libusb installed.
If I run the executable python code(that uses USB module) bu just double
clicking
on it, I don't get any error.
If my java code runs the executable using a Runtime.exe statement, I get that
error

need to be run by the software ; if I try to run that

By default, it is printed to the console, but you can define another
environment variable PYU

Hi
I have been working with PyUSB for a while now.
I am in the process of finalizing a software that
I have worked on and all of a
sudden (well, I am trying the software on new computers) ,
I have got a problem
with usb.core.find!
I have PyUSB and libusb installed on my windows system.
So it
Chris and Xiaofan,
Thanks for being persistent about the WinUSB.
Got my devices responding to usb.core.find(). Finally realized that in Windows,
to access any device using the Python LibUSB you need to make that device
accessible through Windows to your Python program. This is done by using

Guys,
I'm too new at this, so please excuse. I don't even know how to reply in the
thread, so I'm just sending a new email.
The libusb page does not give me anything meaningful. I don't want to write a
driver just yet for a libusb device, just use python to talk to my connected
devices for t

Thanks I'll check this out!
1. Is this mentioned in documentation? Sorry I missed it.
2. When I go to http://www.libusb.org/wiki/windows_backend
I get
"504 Gateway Time-out
nginx/0.8.42"
I tried two different networks. Is this old?

Hi
I cannot get any connected devices (except a libusb device) to reply to
usb.core.find()
If I use a known device like
usb.core.find(idVendor=0x1679, idProduct=0x2001) # Beagle
usb.core.find(idVendor=0x0878, idProduct=0x1101) # Systec CAN
usb.core.find(idVendor=0x0123, idProduct=0x45
