[sane-devel] libusb and sane backend

Currently i'm trying to migrate a standalone program to a sane
backend, i thought that the task would be simpler to migrate it in two
stages: first to make the program a backend but using the libusb
calls, after that and having a working backend, convert all the libusb
stuff to sanei_usb.

however, the backend doesn't work, the port aparently opens well, but
the calls to usb_get_descriptor, usb_control_msg never return.
Any one knows if there is any -bad- interaction between calling
directly libusb and other sane libraries?

Thanks for your help.

There are two kinds of light--the glow that illuminates, and the glare
that obscures.
