Hi all,

I'm using U3 Cruzer USB 1GB flash drive.
As many people may know upon plugging-in it provides both regular
storage device and cdrom functionality.

Before the latest system update I could use and mount both devices
without any problem. Now I've noticed that cdrom device disappeared.

I've checked this issue running the system from both Archlinux 0.8 and
Archlinux 2007.08.1 cds.

The following are the dmesg output after I plugged-in U3 Cruzer USB
flash drive.

Archlinux 0.8:

So something is changed.
Could somebody explain this please?
And is there a way to enable the old behavior?

Cheers,
Sergey
