[sane-devel] Read Errors on Epson 2480 and FC3

I have been working all weekend on this problem. At the beginning, my new 
scanner wasn't even recognized by Fedora. Now, it is recognized but I am 
unable to acquire any images. In all cases, the scanner seems to perform a 
full scan, but no image appears. In the cases of iscan and xsane, the 
preview window never sees an image, although the histogram seems to indicate 
that it sees an image. At the end of what seems to be a reasonable scan time 
- accompanied by lots of mechanical activitiy from the scanner - a pop-up 
informs me that there was a read error because the scanner was busy. 
scanimage behaves the same, giving this error:

$ scanimage >test.pnm
scanimage: sane_read: Device busy

Here's what I get from lsusb:

...and from sane-find-scanner:

# sane-find-scanner

# No SCSI scanners found. If you expected something different, make sure 
# you have loaded a SCSI driver for your SCSI adapter.
# Also you need support for SCSI Generic (sg) in your operating system.
# If using Linux, try "modprobe sg".

found USB scanner (vendor=0x04b8 [EPSON], product=0x0121 [EPSON Scanner]) at 
# Your USB scanner was (probably) detected. It may or may not be supported 
# SANE. Try scanimage -L and read the backend's manpage.

# Not checking for parallel port scanners.

# Most Scanners connected to the parallel port or other proprietary ports
# can't be detected by this program.

Any help would be greatly appreciated.
