[sane-devel] SANE; scanning with LIDE series works under Win, NOT under Lx

Sun Jun 21 00:38:45 UTC 2015

Cedric- I'm sorry you did not receive a reply earlier, the SANE
project is somewhat short handed. In this case, you need to
investigate what changed in your system around the time the scanner
stopped working. Figure out what packages were updated by the OS, and
see if you can downgrade temporarily.

Another thing to investigate is if your system is using the xhci_hcd
module to control your USB ports. If not, we can probably rule out USB
problems.

After that, we would need to get logs of debugging info from the sane
backend, when it is called by scanimage and when called by xsane.
Perhaps we will be able to see some difference.
