I've found an odd problem that's in at least 2.6.0-test11. I've
reproduced this twice now with an Epson 1240 USB scanner
(0x04b8/0x010b). What happens is if I run xsane from gimp, acquire a
preview, start to scan and then cancel, the scanner becomes
unresponsive. If I try and quit xsane, it gets stuck. Unplugging /
replugging and then trying to kill xsane locked the machine up hard.

Here's ver_linux, dmesg and the versions of gimp/xsane I'm running (I've
used the scanner during this boot, without trying to lock it up):
