I only have one device set up with libusb, but to be sure I have changed
the code to
import usb.core as core
usbDevice = core.find(idVendor=0x06C2, idProduct=0x0039)
if usbDevice != None:
usbDevice .set_configuration()
rawRead = usbDevice .read(0x81, 8)
print('Raw: ' + str(rawRead)

How can you be sure your device has been returned here?

Hi. I am trying to connect to a USB device running PyUSB 1.0.0-a1,
libusb-win32 1.2.4.0, under a Windows 7(x86) administrator and python
2.7.1. I have created and installed a .inf file from libusb. Whenever
I try to run a script to read the device, I get an exception reading:
WindowsError: exc
Thankyou so much, that was simple enough.

I installed pyusb on Windows XP SP3 32bit then installed libusb1.0 and then

I can detect usb devices and read their descriptions using
dev = usb.core.find(.)
dev.idVendor
ect.
I can even get down to the endpoints of the USB devices:
Ep = dev[0][(0,0)][0]
But wh
