Что это за ошибка?

[Klesk]

временно сделал ярлык "sudo xsane"
выдавало предупреждение об опвсности сканирования под рутом, но работало, и сегодня перестало
с консоли работает

вот в этой статье http://linux-admin.net.ru/arhiv/iron/scaner.htm сказано, что можно для всех доступ прописать:
"chmod 777 /dev/sga"
но это для scsi сканера, а если сканер usb что прописать?
или как правильно ярлык чтоб под рутом запускалось?

Когда воткнешь сканер, посмотри в dmesg | tail, каким устройством он определился.
И вытягивать ошибки лучше пытаться через
strace xsane
