I think I found a work around for the library scan crash issue. When I copy files to the AK and try to scan immediately, it would often require more than one attempt to get it right - crashing one or two times. However, if I turn it off and restart, the scan runs perfectly the first time. This has worked two consecutive times now. Fingers crossed.
In any case, if you have had trouble with scans, you might want to try turning it off and then back on before running a scan.
I suspect that there might be a driver conflict or memory issue from using the usb connection.
I hope this works for you guys. Let me know if it does or not. We can determine how effective this is in addressing this problem.
