I thought I would try and write a backend for SANE. I have used UsbSnoop on windows to collect some of the URB Data. What is the equivalent program on linux to snoop USB to see what I am actually sending ? With any luck the output of both should be the same.

This happens when it short-circuits itself(i guess) responding to an errorneous register write. I suspect register 0x03 is responsible(lamp power etc.). The attached patch should clarify this, by giving the scanner more time to react on the register writes. The last successfull write should be the one leading to the reset.
