Title:
simple-scan does not communicate with scanner, also it is found with
"lsusb" and "scanimage -L"
Status in simple-scan package in Ubuntu:
Invalid
Bug description:
It seems simple-scan can no longer communicate with my scanner,
although it was able to scan with the same hardware before. The
hardware is found, but simple-scan reports communication errors. The
hardware itself works.
