My device is a CAN/LIN - USB interface, i use the gadget zero pid/vid just for testing, after that i'll buy another vid/pid.
I'm not the first one who detect this problem, I have found in libusb mailing list the same problem but the discussion is not complete : http://www.mail-archive.com/libusbx-devel@lists.sourceforge.net/msg01543.html My OS is Windows 7 32bits, I tested the program on 3 machines (all with win7 32bit) but the problem persist. It's possible that the embedded soft in usb card causes the problem ? because in my program example, there is just open close open !
