Worked for me, thanks!  After Sandy Pond's chmod magic scanimage found
my Epson 1650, although it gets a bit confused:

[root at tabb1 root]# scanimage -L
device `v4l:/dev/video0' is a Noname BT878 video (Hauppauge (bt878))
virtual device
device `epson:libusb:001:003' is a Epson GT-8200 flatbed scanner

Then xsane finally works as root.  Now to try as a user...

Mine also, but brute force (eyeball) still works.

Thanks all,
