Hi, hope you guys don't mind me jumping straight in and aksing a
question.

I believe I am the leader in the evolution of USB device usage, I
recently purchsed a USB 2.0 CDROM case, and placed in it a working
DVD-DOM drive.  I say i'm the leader only to make light of my lack of
discovery of previous trouble/success reports on this particular usb
combination.

My final goal is to purchase a DVDRW to put in the case, but I though it
would be prudent to test it with a DVDROM first..  See the case details
here:

Using USB, the DVD-ROM reads CD's and single layer DVD's fine.  But it
worn't read dual-layer (DVD-9??) disks.  Well, it will, just not very
well..

dmesg shows lines like this (alot) after trying to read:
I/O error: dev 0b:00, sector 9372632 
I/O error: dev 0b:00, sector 9372640 
I/O error: dev 0b:00, sector 9372640 
I/O error: dev 0b:00, sector 9372648 
I/O error: dev 0b:00, sector 9372648 
I/O error: dev 0b:00, sector 9372656 
I/O error: dev 0b:00, sector 9372656

What could be wrong?  The DVD laser works, as when I plug this into a
windows (i know, i know, but it works..) PC, i can play the DVD.. 

What can I do to troublshoot this?  I'm at a loss..

My kernel is 2.4.22.

Cheers,

Mick
