@Husse I have a Brother multifunction (printer/scanner/copier) and I can't get the scan to work because of some oddity with usb.
I had that with Suse and it was because it was "seeing the usb port was busy with the printer" and had to load a patch for sane, was an rpm will try to remember (sane-not-busy?)
When he first installed the system he did not have a Umax scanner so maybe at that time they were not needed?
When I first started Linux it only loaded the kernel modules of the hardware it found on install (mainly) if you changed the soundcard you often had to re-install, or recompile kernel, are the scanner modules loaded as required at install?
This package includes some backends that are not yet included into the
official SANE distribution. Currently, they are :
* epkowa (some EPSON scanners)
* geniusvp2 (Genius ColorPage-Vivid Pro II)
* hp_rts88xx (HP ScanJet 4400C, HP ScanJet 4470C)
The conversation was here:
and the fix worked for the Brother also
The package was ignore-EBUSY-from-USB
