Perhaps you can use 'sdparm' to determine what's going on? I have a problem with USB 2.0 devices on my HP laptop, with Debian, and one suggestion made was to disable STANDBY mode with sdparm.

I do not recall, nor can I find, the web page referencing this. But the problem was described as a disk that went into standby mode would not wake up correctly. The fix was to disable this mode.

I'll continue searching and see if I can find the reference, but I figured others might know about it and post quicker than I can.
