Thanks for the responses!
I have read up more, and still have the same type of issues. I have
revisited my request type:
usb_control_msg(handle, USB_RECIP_INTERFACE | USB_ENDPOINT_IN, 1,
0, 0, buff, 64, 10);
however still recieve errors in Windows (**this works fine under linux
using usb.h). Should return a string, but am getting:
libusb0-dll:err [control_msg] sending control message failed, win
error: A device attached to the system is not functioning.
I did as Xiaofan suggested and loaded the debug version. The output is
attached.
Any further direction would be most appreciated...
