My further tests discovered one substantial drawback of using the
scsi driver for both - emulating the CD drive and mounting USB
storage.

Evidently I have to plug in all USB devices I want to use *before*
I load the modules for the CD burner. When the CD drive is recognized
at scsi0, scsi1, etc. the USB support will not recognize any new
USB devices plugged in later. It only recognizes those which have
been plugged in an recognized at the addresses below the CD drive.

Can anybody tell why? Is there a way to emulate the CD- IDE drive at
a higher address and win some place for other USB devices?

Probably hotplug would work but the kernel would be larger and I have no idea how to use it. I can try to compile a kernel with hotplug and kmod, and then there is some hotplug.tgz package that I never looked at. Read about this first and let me know what modules would need to be added.

I always put in my USB storage device before loading the modules.
I think I can then take it out and put it in again and have it found.
Experiment some more or read online.
