Are there perhaps diagnostic tools or an error log that can be enabled
so I can see if maybe there is some sort of error occuring with the USB
transmissions that might be causing this problem, or perhaps what part
of the driver code it is getting locked up on?.
Has anyone else experienced problems such as this with USB disks? If
more information on my hardware is needed i will post dmesg output.
Any help is appreciated.
