Looks like a kernel bug. Probably in the SCSI driver? Try scanimage at the command line (CRTL-ALT-F1, not an xterm). E.g. scanimage >image.pnm. Do you get messages from the kernel in this case? > When connectet to the USB, only Xsane freezes. When I dissconnect the > scanner from the powersupply, than the System freezes. That last one may be also a kernel bug. It occurs if you unplug the scanner and then try to read from or write to it. Please show us log files for the xsane freeze, e.g. SANE_DEBUG_UMAX=255 SANE_DEBUG_SANEI_USB=255 xsane 2>log And now try to get the freeze. The debug messages are in the file "log". > Where to search the error.

But as both USB and SCSI fail, tehre may be also a problem with the backend. Bye, Henning
