Comment 238 for bug 85488

Jaime,

The scanner still gives troubles. Sometimes it works as it should.
I tried different USB ports and sometimes it works. The latest thing I
tried was switching of the power of the scanner and on again. Than it
worked but I'm not sure if this action is the reason.
Anyway, as soon as the scanner works it keeps working so far as I can
see. But after a cold boot (switching on the PC) it is possible that the
scanner doesn't work anymore and that you have to do some magic tricks.
