Do you mean fopen the dev node and r/w it?
like 	fd = fopen(filename, "w")?

BTW, I change the venderid/deviceid in /libusb/examples/dpfp.c to get
familiar with the lib apis.
But it return message as:
usb_claim_interface error -6

>From source code, -6 means it is busy.
I try it again by umounting the usb flash disk, but the error is still the same.

Is there anything I have to do before testing libusb api?
appreciate your help,
miloody
