Failed to start:Invalid argument
If I click on the scan button a second time after I close the error dialog, then the scan is performed. This happens in Xsane and Xscanimage. Simple Scan just fails to scan and Gimp fails to scan with the xsane plugin.

I tried putting myself into the lp group as per a posting online, but no change.
Scanner is set up directly under USB and the latest Brother drivers are installed.
the following is /var/log/messages when I run Xsane
