This usually I used google to find other instances of the error, and I noticed that other people had a "timeout" error before the usbdevfs error. I did not have the "timeout" error, just normal logs setting up the scanner. > indicates the scanner is stuck after it received something that > confused it, for whatever reason. It could also be a bug in the USB > layer, you could try to upgrade your kernel if it's not current. It worked a couple of months ago, and I didn't change the kernel or anything else except for doing normal daily upgrades of Debian (probably including usb, sane, and hpoj packages). So the kernel should work? Maybe? My 2.4.19ac4 kernel is old, but I am horribly clueless about kernels. I tried installing a stock Debian SMP kernel and it didn't work. I tried the menuconfig thing and the kernel didn't boot either. So apparently I'd need handholding for kernel upgrades, or at least a really good tutorial that I know is up to date and relevant (and doesn't talk about initrd as if I knew what it is :-)). In short, I am afraid of the kernel. :-) Thanks for replying. I *really* appreciate it. Here is the debugging output: ~# SANE_DEBUG_HPOJ=255 scanimage -v -y 279.4 --mode lineart --resolution 300 --batch-scan=yes --batch=aaa--%02d--line300.pnm Scanning -1 pages, incrementing by 1, numbering from 1 Scanning page 1 scanimage: scanning image of size 2544x3299 pixels at 1 bits/pixel scanimage: acquiring gray frame scanimage: read 1049082 bytes in total Scanned page 1.
