"So the device is x1190 ...... but the lsusb does not mention x1190"
Thank you for the response.
I think in this case there is a member of series X11xx. Both in the Live CD and the installed and updated PCLinuxos the lsusb show the same lines:
Bus 002 Device 009: ID 043d:007c Lexmark International, Inc. Lexmark X1110/X1130/X1140/X1150/X1170/X1180/X1185
Bus 002 Device 010: ID 043d:007b Lexmark International, Inc. InkJet Color Printer
"Does lsusb give the same output on the liveCD?
When using the liveCD is it set up as x1190?
Does the x1190 appear in the list in the setup within PCC?"
3. no. First the scanner list is empty and ask me to setup the scanner manually. After selecting the Lexmark X1185 (this is the highest number) and save it, ask me that USB scanner is found.
I think it would be better return to libsane 1.0.21 instead of the actually libsane 1.0.22 version or to wait for the next version.
