Driver for In-System USB hard drive box

Driver for In-System USB hard drive box

[Richard G. Holst]

All,

I am a bit confused and need some help.

I am trying to get my external USB hard drive manufactured by In-Systems
Design  to connect to my RedHat 7.0 running a 2.4.2 Kernel. The hardware is
an Asus P5A motherboard with 128 MB of ram and a K6-3-450 Processor.

I checked and made sure the HotPlug was turned on and all the USB stuff in
the kernel was set to module. I can manually load the usb-ochi and the
usb-storage modules. When I load the storage module, I can see the LED on
the USB drive blink four different times. I checked the
/proc/sys/kernel/hotplug file and it does contain the path to /sbin/hotplug.
I put a echo statement in the /sbin/hotplug file as a test, and the file
does execute every time I plug the USB drive in and every time I unplug it.
Further investigation found that the /var/log/messages file was having the
following lines added when I plugged the drive in:

	kernel:  hub.c  USB new device connected on bus1/1, assigned device number
5

	/sbin/hotplug: ... no driver for USB product 5ab/31/100

I though that the usb-storage.o file was the drive of USB storage devices?

Does the USB hard drive require a special driver in addition to the modules
I have already loaded?

I checked the WEB site of In-Systems and there is no Linux drive posted. I
emailed their tech support and the claim that I should not need a driver for
Linux that it is already built into Linux.

Could someone please explain?  Does every USB device I want to connect to
Linux need an additional driver or are some drivers already present? How do
I know which drivers to use?

Thanks in advance,

Dick Holst

Check the latest usb-storage code out of the CVS repository wiht

cvs -d cvs.linux-usb.sourceforge.net:/cvsroot/linux-usb co storage

And try with that code.  The In-System driver is relatively new.

Cut/pasted from some email of yesterday is the way to find out
what's really going on ... try with the latest scripts.

- Dave

So the problem is only to find out why the usb.agent script doesn't
handle it.  I have my guess below ... but you can debug such things
yourself pretty easily.

You can snapshot the environment variables given to the hotplug
script, or an agent, by adding a line line "env > /tmp/variables"
to the script.  Then turn those into a script that just assigns and
exports (!) the variables listed up at the front ... use it to call
"sh -x usb.agent" (or "pci.agent" or whatever) to see exactly
what it's doing.  With that kind of debug output, it's easy to find
and fix problems.
