Hi,

I have a small program which try to read and write USB device. The
problem is I must be root to do that, I changed /dev/usb/lp0 mode, made
it accessable to everybody, but useless. I can find device, do usb_open
and usb_set_configuration, but after that, usb_claim_interface will
return -1. Yes, I can use root to do that, but it should have some way
to change the device's access mode. Did anybody can help me?

Thanks a lot. 

Lan Zhang
