------- Comment #2 from armagon_ca at yahoo.ca  2006-12-15 23:19 -------
This bug that I wrote up appears to be a duplicate, but it does offer more
detail and a work-around, so I am pasting it here.

Bug: ohci-hcd module is not automatically probed on Akita

SUMMARY
-------

By default, the lsusb command shows nothing on a Sharp Zaurus SL-C1000 (Akita)
with Angstrom 20061214 installed.  I finally realised that this was because the
ohci-hcd module had not been probed.

STEPS
-----

I flashed the Angstrom test build from
http://www.angstrom-distribution.org/unstable/images/20061214/akita/ onto my
Akita.

After logging in as root, I tried the 'lsusb' command.  It showed nothing.  

I plugged in a USB keyboard, and it was not detected; furthermore, none of its
LEDs lit up.

WORKAROUND
----------

The results of 'lsmod' are:

irda                  113128  3 pxaficp_ir,ircomm_tty,ircomm

noteable in their absence are modules such as ohci_hid and usbcore.

I decided to try a 'modprobe ohci-hcd'   Text appeared on the screen and my USB
keyboard was detected.

[Wow!  It worked better than ever.  None of the keys appeared dead.  It even
recognized me pressing Num-Lock and Scroll-Lock, and noticed when I pushed the
special 'Power' button on my keyboard!]

DESIRED RESULTS
---------------

A user should not have to modprobe ohci-hcd manually.  On the Akita, and other
devices that support USB, this should happen automatically.
