Third attempt, trying to work my way around alioth's ridiculous
anti-spam measures...
My trusty Epson GT-7000 died today. Annoying, but not the end of the
world, given that I also have an Epson Stylus Office BX300F all-in-one.
However, I can't get it working with sane:
riva:~# scanimage -L
device `epson:libusb:001:003' is a Epson NX300 flatbed scanner
device `net:localhost:epson:libusb:001:003' is a Epson NX300 flatbed
scanner
riva:~# scanimage
scanimage: sane_start: Operation not supported
Running with extra debugging gave a clue:
USB error: could not set config 1: Device or resource busy
Removing the usblp module fixed that, but it still gave me the
"Operation not supported" error. The debugging output is now:
riva:~# SANE_DEBUG_SANEI_USB=128 scanimage

I tried running it under strace to see if I could find out *which*
operation wasn't supported, but without success. The end of the
output looks like:

close(4) = 0
write(2, "scanimage: sane_start: Operation"..., 47scanimage:

) = 47
I can't see any obvious failures there apart from the initial
USBDEVFS_SETCONFIGURATION ioctl. Is that the problem here? If
so, I wouldn't have expected it to go on to claim and release
the interface. What can I do about it? I'm not sure what to
try next. Any ideas?
Thanks,
Tet
