Hi,
I'm trying to use a USB device under Windows7x64.
The device is HID like with custom protocol.
The USB device is recognised by Windows as a HID device (without error
nor warning shown is
ck
raise USBError(_strerror(ret), ret, _libusb_errno[ret])
usb.core.USBError: [Errno 22] Invalid parameter
As I am far from a USB ninja, I spent days documenting myself and
searching the Internet for a solution without success.
What's wrong with my code ?
