I purchased a "Genesyslogic" usb/ieee1394 hard drive which I started
fiddling with yesterday. While I was able to get everything working just
fine with the ieee1394 and the sbp2 driver, I was unsuccessful with the usb
support. (I did test the drive on a Win2K computer, and with the help of
explore2fs, it worked quite nicely, so I know the drive is functional.)
While the sd_mod module does identify it as sda, I can do nothing with it.
Does anyone have and suggestions?
I am using RedHat7.3 (kernel 2.4.18) on a PentiumIII/800
Here is the run-down:

After plugging in the drive, RedHat7.3 autodetects the mass storage device
and loads the usb-storage device. I manually loaded the sd_mod driver...
here is the syslog:
