Re: libusb_claim_interface failed on Windows7

Of course 1.0 api work under window ;) 

like Xiaofan said you may have to install some backend driver like winusb or
libusbk for your device get you claim interface to succeed. 
It is strange that with some old compat version you can claim interface 

just for curiosity why do you need libusb_get_port_number ? give a look at
usb_get_port_numbers instead 
for my own purpose i use libusb_get_device_address and 
libusb_get_bus_number to build a kind of "id" unique for a device  also note
that none of this call require to open the device nor claim interface.
