Hello,
I just got Umax Astra 4450 (same as 4400 except with UTA?) for a while and 
tested it with SANE. Unfortunately, it does not work. The lamp turns on and 
the head moves a bit, then goes back (two times) and the scan ends with these 
errors:

[rts8891] simple_scan: failed to wait for data
[rts8891] gain_calibration: failed scan data
[rts8891] sane_start: failed to do gain calibration!
scanimage: sane_start: Error during device I/O

The full log is available at 
http://www.rainbow-software.org/linux_files/umax_astra_4450/scan_failed.txt

I've made some SniffUSB dumps from Windows:

http://www.rainbow-software.org/linux_files/umax_astra_4450/umax-vistascan-run.log.gz

http://www.rainbow-software.org/linux_files/umax_astra_4450/umax-scan-75dpi-uta.log.gz

but haven't examined them yet.

BTW. There's wrong info on the web device list - Astra 4400 is marked 
as "good" but sane-rts8891(5) says that it's untested.
