Driver for In-System USB hard drive box

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.

C:  Then what are those blue and white screens I get every day?

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

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.
