Hello Greg et al., I'm afraid I'm back with another problem. I tried to run the scanner as UID 0 again and got this new error:
scanimage --list-devices [epson] Unknown type or level B, using B3 device `epson:0x378' is a Epson flatbed scanner default device is `epson:0x378' plus the scanner is no longer identified as Expression636. Turning the scanner off and on does not help. This is the testing output with debug (I'm scared of thinking I may have messed up the internal scanner firmware or something): SANE_DEBUG_EPSON=9 scanimage --list-devices [sanei_debug] Setting debug level of epson to 9.
