[Libusb-win32-devel] set_configuration problems

[Fouzi B. <fou...@tr...>]

Hi,

I'm trying to write a little program to communicate with a USB device 
(ChipCard Reader) through the libusb-win32.First, I tried to send a 
usb_bulk_write message without setting configuration, I had a "invalid 
configuration -1" error; so I tried to set configuration with 
bConfigurationValue before sending the bulk message but when I run the 
program, it freeze totally until I detach the device physically or 
reboot the computer ! I tried also to set configuration with other 
values, the program doesn't freeze but I had a "wrong parameter" error.

thank you for your help in advance.
