That is the only relevant information I see in the proc system and 
syslog. I will be happy to send you more diagnostic info if you could 
suggest what to look for where? I think it is just a question of 
relatively poor auto-hardware detection in RHEL. Market is full of 
portable USB drives (disk as well as flash based), RHEL particularly 
lacks support for many. I am wondering if users can modify USB drivers 
to narrow the gap.
