Intermittent USB Scanner Problem
Hi, I have a problem with my UMAX astra 2000U scanner. I have not been able to get it to work properly, it is sometimes recognized and sometimes not. After verifying that the scanner was supported (it said "minimum but should work"), I downloaded the appropriate back-end from the sane web site (umax1220u). I have upgraded to the latest version of libusb. I am running Kubuntu with a 2.6.15-26-386 kernel. Here are some things I have noticed:
Xsane almost always says no devices available, but sometimes it recognizes the scanner and says there is an i/o error.
Quiteinsane gives the same response when it finds the scanner, but mostly it doesn't find it at all.
Kooka usually recognizes the scanner but just hangs when I try to scan something.
Here is some output from my toubleshooting:
scanimage -L (in root and normal account)
No scanners were identified.......
#This isn't always the case, sometimes it finds it
sane-find-scanner (root and normal account)
No USB scanners found......
#is always like this
lsusb
Bus 001 Device 002: ID 1606:0030 Umax [hex] Astra 2000U
