usb hotplug problems with 2.6.10

[howarth@bromo.msbb.uc.edu (Jack Howarth)]

Alan,
   I had mentioned a couple weeks back that with kernel 2.6.10, 
the ability to hotplug usb keys in Fedora Core 2 and 3 has been broken.
There is actually a bugzilla report on this with some useful information
on manifestation of the problem....

https://bugzilla.redhat.com/beta/show_bug.cgi?id=119140

The problem can be hacked around for the moment in hotplug by
repeatedly calling updfstab until the device appears in both
/proc/scsi/scsi and /sys/bus/usb/drivers/usb-storage but it 
would be nice is this could be fixed in the kernel. Hasn't any
distributions other than Fedora run into this yet?
                     Jack
The hack recommended by Jason Tibbitts that works around this problem
is...

 }

...its ugly of course but at least hotplugging usb keys work again
under 2.6.10.
