Re: [Libusb-win32-devel] Could not claim interface- requested resource in use.

[Mark B. <mb...@ze...>]

Could be that another driver has connected to the device. I had this 
when I was trying to use libusb-win32 to connect to a mouse (just to 
check how to use it!) - I had to overwrite the mouse driver with libusb, 
even when using the filter driver. I'm a newbie too, so can't help much 
unfortunately.
