Hi!

I didn't know USB storage was also 'seen' as SCSI, I know that sdx and 
stx are SCSI units (or SATA units on my other box). But this 
continuously logging of the checking for media isn't really normal 
behaviour is it? I had a system with SCSI CD reader and a SCSI writer 
and I never saw this kind of logging or console messages. Can I turn 
this logging off?
Besides that, where are the 'sda' lines coming from then?

Kind regards, Angelo
