# Reseting USB for scanner

This is a question on:superuser, since one reply suggested I ask here...

My distro does not yet have a backend for my scanner, but the last release of SANE does. So I downloaded the source and installed.

Scanning goes fairly well except that for some reason at the end of a scan I get an error message:

"reset high speed USB device using ehci_hcd and address xx"

After that I can't scan anything until I unplug and replug the ( USB ) scanner.

Since I expect my distro to pick up the latest sane version within a few months, for now all I would like to do is reset the scanner so it can do the next page.

Any suggestions on how to do this?

PS: The kernel version is: 2.6.31-22

It might be handy to know the distro and scanner. –  Gert Sep 22 '10 at 9:14

You could try a modprobe -r ehci_hcd so the USB 2.0 module will be unloaded and uhci_hcd is used.
