Some time ago I have upgraded my linux distribution to include USB support,
with kernel 2.2.16 from the Red Hat 7.0 distribution. Then I bought a USB
Iomega Zip Drive, 100 Mb, that I planned to use on my Toshiba Tecra 720 CDT
laptop. Later on I was told that in order to use the usb-storage module I
needed to upgrade to kernel 2.4.x, so I compiled 2.4.2 with kgcc and making
sure that all the packages needed were up to date.
Despite the support received from several newsgroups, I have had little
success, as I am still unable to mount my zip drives.
The main problem is that, approximately 70% of the times, my laptop would
not boot at all, freezing when loading the usb-ohci module (I have a NEC
Corporation USB controller, rev 01) or, if that step is passed, it
freezes when mounting the USB filesystem, or later, when checking for new
hardware. Some times I have to try booting my laptop 6 times and more before
I can start working. If the machine boots, I can work happily but loading
the relevant modules and mounting the drive has no effect.
I have decided that, on a temporary basis, before I manage to dedicate some
time to study what is needed to sort out al these problems, I should let my
laptop boot smoothly, thus I would like to remove USB support completely at
start-up. I am sure there is a way out, but I have invested so much time to
date that is time now to meet the deadlines for the work that I have got to
I don't know whether this has to be done by Kudzu, by chkconfig or what.
Could anyone please help by telling me how to control hardware support at
Thanks in advance
