If the kernel doesn't see your scanner, you should tell him, for what
to look :-) Have a look at the output of "cat /proc/bus/usb/devices".
You should find a lines like that:

T:  Bus=01 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#=  2 Spd=12  MxCh= 0
D:  Ver= 1.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
P:  Vendor=055f ProdID=0006 Rev= 1.00
C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=496mA
I:  If#= 0 Alt= 0 #EPs= 3 Cls=00(>ifc ) Sub=00 Prot=00 Driver=usbscanner
E:  Ad=01(O) Atr=02(Bulk) MxPS=   2 Ivl=0ms
E:  Ad=82(I) Atr=02(Bulk) MxPS=  64 Ivl=0ms
E:  Ad=83(I) Atr=03(Int.) MxPS=   1 Ivl=1ms

That's for a Mustek scanner, but Epson should look similar. If there
is a "Driver=(none)", your USB system has detected the scanner, but
ther scanner driver hasn't. In this case note the vendor and device
ids (from line "P:") and try:

rmmod scanner; modprobe scanner vendor=0x055f product=0x0006

Use your ids instead the Mustek ones. Try cat /proc/bus/usb/devices

Now sane-find-scanner should find your scanner. Ream man sane-epson
and edit epson.conf.

By the way, the "unable to access minor data" errors can be ignored.
