This may be a duplicate message. If so, sorry ,mozilla crashed on
me.
I just installed 2.3.99-pre2 (unpatched), and my usb-cdrom drive stopped
working. With 2.3.99-pre1 (unpatched), the drive worked fine (though I had
to be careful to install modules in the right order). I used the same
configuration options for both kernels, and haven't changed anything else.
The usb-uhci module appears to work ok (I get the normal screenworth of
text when I plug the cdrom in, and the /proc/bus/usb/devices for both kernels
looks very similar), so I am assuming the problem is either with the usb-storage
or scsi modules. 'modprobe usb-storage' gives no messages (debug is turned
on) with the pre2 kernel (I got a message identifying the drive with the pre1
kernel), and /proc/scsi/scsi shows no devices. I have included all of the
information I could think of for both the pre1 and pre2 kernels below.
