[wplug] usb storage and compact flash readers.

[John Harrold]

Sometime in September Carl Benedict assaulted the keyboard and produced:

| John,
| 
|    What does an `lsmod` yield?  I use a SanDisk ImageMate CF-SM.  I seem
| to be using 'usbcore' 'usb-uhci' 'usb-storage'. I believe those are all
| required to use USB devices.  Also 'ov511' and 'videodev' seem related. 
| I think they are part of the USB DigiCam packages.  I mount mine as a
| SCSI device (i.e. /dev/sda1, etc).  From what I remember, the
| usb-storage driver uses some type of SCSI emulation mode for block
| devices.  I seem to also remember there being some kernel requirements. 
| I am running RedHat 8, and got it working out-of-the-box.
| 
| My /proc/bus/usb/drivers shows:
| 
|          usbdevfs
|          hub
|  96-111: hiddev
|          hid
|          ov511
|          usb-storage

usbcore and usb-storage are loaded. when i try to load usb-uhci i get:

[root at home root]# modprobe usb-uhci
/lib/modules/2.4.20-8smp/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.
You may find more information in syslog or the output from dmesg
/lib/modules/2.4.20-8smp/kernel/drivers/usb/usb-uhci.o: insmod
/lib/modules/2.4.20-8smp/kernel/drivers/usb/usb-uhci.o failed
/lib/modules/2.4.20-8smp/kernel/drivers/usb/usb-uhci.o: insmod
usb-uhci failed

| Prehaps loading the 'ov511' and 'videodev' modules will get it running? 
| I would make sure 'usb-uhci' and 'usbcore' are present and loaded as
| well.  Hope this was of some help.

[root at home root]# lsmod  |grep -E "usb|ov|vid"
ov511                  83200   0  (unused)
videodev                8544   0  [ov511]
usb-storage            69884   0  (unused)
scsi_mod              110520   3  (autoclean) [usb-storage sg aic7xxx sr_mod]
usbcore                82592   1  [ov511 usb-storage hid]

my /proc/bus/usb/devices is still empty though.
