I assumed there's no work being done on this atm, so I wrote a small 
patch that adds a driver blacklist to usb autosuspend. Tried to stick 
with the sh syntax, but I only have bash, so I couldn't test if it's 
truly sh compatible. It uses the readlink utility to read the "driver" 
symlink, but I guess readlink should be present on any linux system. I 
tested it on my system and it seems to work fine so far.

greetings...
