[sane-devel] BenQ 5000 on Fedora 15 is detected, but will not scan

Hi,

I have a BenQ 5000 Scanner. It is labeled as "Alaska 5000U", but is detected
as BenQ 5000.

I've set-up the scanner as the snapscan page suggest. I'm using the
20F8V114.bin firmware that came with the original CD.

Any hint on how to make it work?  I can provide more data if needed.


The test case is as follows:

Step 1: Connect scanner and detect:
