USB Question...

[Brian Chabot]

I recently got a (rather nice otherwise) sound recorder that connects 
via USB to a computer.

When I plug it in, I get this in my /var/log/messages:

...with the last two lines repeated for each block it cannot access 
(several pages)...

It mounts fine any way.  Then, as I try to copy files, something 
happens... my MP3 sound clips get mangled.  Not much... but when played, 
they go about 5 seconds, then repeat the last 3 where the next three 
should be, and so on.

Anyone have any ideas what's going on here?  Is the device not liking my 
low-speed hub?  Is the memory on the device bad?  How might I check?  FSCK?

...cound be I'm not thinking straight at almost 4:30 am... but I'm at a 
loss here.  Any help would be appreciated.

Thanks!


Brian
