Ben,
at last I did as you suggested. I backed up all my data an installed OM from scratch, included home partition.
Now my system is almost like before. I still need to fix a couple of things:
- lack of dual boot. OM bootloader is not able to recognize and boot my Windows partition anymore. Is this due to uefi bios or something else?
- lack of permission for running my scanner as a user. Actually it works with root permission only. I found a solution time ago, but I can’t remember what it was.
‘lsusb’ returns (between others):
Bus 001 Device 007: ID 07b3:040b Plustek, Inc. 600DPI USB Scanner
but ‘sane-find-scanner’ returns:
could not open USB device 0x07b3/0x040b at 001:007: Access denied (insufficient permissions)
I tried to put chmod o+rw /dev/bus/usb/001/007 in /etc/rc.d/rc.local, but nothing changed.
Is there a way to give permanent RW permissions to that usb device?
