[sane-devel] Error during device I/O running saned on WL-500GP under OpenWRT using libusb

[fireandy]

Sorry, but what are interrupt usb endpoints? Is it the way, the device is
read / written by using libusb?
The USB-Chip in the Box is a VIA 6212. Kernel is 2.4.34 used libusb is
0.1.12-1 

By searching I found the following: 
http://www.nabble.com/usb_interrupt_read-with-libusb-0.1.12-and-kernel-2.4.2
7-to4452928.html

Also a discussion about libusb with interrupt endpoints, where the person,
that states it is not working, receives the same returncode -22 (invalid
argument) as I see, when I do a dmesg. So I would have to give it a try with
Kernel 2.6.x?

Cause I can't find no scanner Kernel module for 2.4.34 for OpenWRT that I
could use as an alternative way of getting data from / to the device.

I mean..there was not nothing - scanner gets detected and moves around...
