Problems defining an udev rule for usb-daq board
Hi all,
I've got trouble configuring an usb-daq board with udev. I use a recent self-compiled kernel (2.6.16-2-686) on Debian testing with comedi-0.7.72 and an usb-daq board (usbdux). The daq-board runs perfect, but I can't figure out how it can be automagically configured by udev when hotplugged. After connecting the board, one had to execute the following command (as root):
/usr/local/sbin/comedi_config -i /usr/local/share/usb/usbdux_firmware. hex /dev/comedi0 usbdux
I tried the following udev-rule without success:
KERNEL="usbdux", SUSBSYSTEM="module", SYSFS{refcnt}="0", RUN+=" /usr/local/bin/config_usbdux"
where "config_usbdux" is a shell-script with the comedi_config command above.
The following output might be helpful:
# udevinfo -a -p /sys/module/usbdux/
[...]
looking at device '/module/usbdux':
KERNEL="usbdux"
SUBSYSTEM="module"
SYSFS{refcnt}="0"# udevinfo -a -p /sys/bus/usb/drivers/usbdux/
looking at device '/bus/usb/drivers/usbdux':
KERNEL="usbdux"
SUBSYSTEM="drivers"
After connecting the daq-board, dmesg shows:
usb 5-1: new high speed USB device using ehci_hcd and address 34 usb 5-1: configuration #1 chosen from 1 choicecomedi_: usbdux_: finding a free structure for the usb-devicecomedi_: usbdux: usbduxsub[0] is ready to connect to comedi.comedi_: usbdux: ifnum=0comedi_: usbdux0 has been successfully initialised.
After configuring with comedi_config dmesg shows
comedi0: usbdux: uploading 1471 bytes to addr 0, first byte=2.
comedi0: usbdux: usb-device 0 is attached to comedi.
comedi0: attached to usbdux.
Now the board is ready to use,. Any ideas? Thanks in advance, Sven

You plug into the module-load event. Are you sure that the module isn't already loaded when you connect the device? And how will the module-load event, that calls your script, find the the device?
Why don't you plug into the event for the device to upload the firmware?

The module usbdux is automatically loaded when the device is connetcted.

How? I don't know much about udev, but it worked with kernel 2.6.8. and the hotplug scripts.
Thanks, Sven

The module usbdux is automatically loaded when the device is connetcted.
But only the first time you connect a matching device and never again, except you unload it manually.

Run 'udevmonitor --env', plug-in the device, pick from the list of events the one for the device and use this.
Try the one which contains the correct DEVNAME and use that value as the device node name you upload the firmware to.
Good luck,
Kay

Hm, do you have a pointer to where you got the usbdux code from? It's not in the main kernel tree, right?

The usbdux code is part of comedi, see e.g. http://www.comedi.
org/download/comedilib-0.7.22.tar.gz, more information about the daq board is here: http://www.linux-usb-daq.co.uk/.
Thanks, Sven

Ah, ok, that fun thing :(
Try asking the authors of that code to fix it up, as it is not under the GPL, I'm not allowed to touch it, sorry.
good luck,
