Re: [Libusb-win32-devel] Return values

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Hi there,

One more thing to add:

when I call the function usb_set_configuration(devH, 1), if I change the 1
to zero, then I pass thru the configuration, but then I don't get to claim
the interface (get an error on this function: usb_claim_interface(devH, 0) .
I tried changing the number on this function too, but it didn't work.

Hope that helped a bit.
