The problem seems to be solved. Apparently, the change configuration
command could be accepted only when the device is in reset state. The
on-chip bootloader specifies that.
Thanks for your help.

Hi,
Yes, that's right. I saw an example code online for the same device, which
is receiving data, using configuration 3. So they've used
set_configuration(3) function.

Hi
My end device connected via USB is a PIC18F4550 microcontroller. For
details on this board, kindly look at www.hackinglab.org or

Meanwhile I will check on the libusb version.

I am working with python in Ubuntu 11.10. I'm able to detect a USB device,
access its properties etc. Now I want to establish USB communication. As
given in the pyusb tutorial webpage, I gave a command
pingu = usb.core.find(idVendor = 0x04D8, idProduct = 0xFEAA) #this is
working fine now, and then
