Thanks for replying but I really don't know why you bothered with a
whole *2-line* answer.
If you haven't got the time to write anything useful, it would be better
if you didn't write anything at all. God knows which section of the FAQ
you might be trying to point me towards.
OK I'll accept that maybe my earlier message didn't contain enough
information to be able to diagnose the problem but it might have been more
helpful to suggest what information might be important.
If the fact that the device is logged as being disconnected and
re-connected is not evidence of hot-plugging then I don't know what is.
Anyway, in the hope that there is someone on this list who may be able
to help me get USB storage working; I don't believe the problem is with
hot-plugging per se but the fact that my Compact Flash reader does not
appear as a SCSI device in /proc/scsi/scsi.
Here's some more information that was missing from my earlier post. I'm
running SuSE 7.3 with kernel 2.4.16
This is what happened when I switched the reader from one USB port to the
other port and back again. (excerpt of results from 'dmesg | grep usb')

This is the error message I get when I attempt to
do a 'modprobe usb-uhci'
============================================================
> # modprobe usb-uhci
/lib/modules/2.4.16-4GB/kernel/drivers/usb/usb-uhci.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including
invalid IO or IRQ parameters

failed
/lib/modules/2.4.16-4GB/kernel/drivers/usb/usb-uhci.o: insmod usb-uhci failed
============================================================
Obviously this is indication of trouble but what is the likely cause ?
Does the output from the 'dmesg' command above indicate that usb-uhci
support is installed and working correctly already ? Am I trying to load
the wrong module here ? Does this error mean the module already loaded ?
Here are excerpts from my /var/log/boot.msg file showing the
relevant USB stuff:

I hope I've included all the necessary information this time. If not,
please let me know what's missing.
Any useful advice would be very gratefully appreciated. TIA
