Subject: Problems defining an udev rule for usb-daq board
Date: Fri, 18 Aug 2006 10:59:34 +0000 [thread overview]
Message-ID: <7713092.1155898774121.JavaMail.root@ps14> (raw)
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 choice
comedi_: usbdux_: finding a free structure for the usb-device
comedi_: usbdux: usbduxsub[0] is ready to connect to comedi.
comedi_: usbdux: ifnum=0
comedi_: 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
