Re: issues getting I/O device to work with udev....

Thanks.  I changed 10-edredaq.rules and z-edredaq.rules to both be

SUBSYSTEM="edredaq", SYSFS{edredaq_nodename}="device*", NAME="edredaq/device%m"

Now 'udevtest edredaq/device0' has just this error message left:

main: unable to open 'edredaq/device0'


Here is 'udevinfo -a -p /sys/class/edredaq/device0' output if
useful...

==========
udevinfo starts with the device the node belongs to and then walks up the
device chain, to print for every device found, all possibly useful attributes
in the udev key format.
Only attributes within one device section may be used together in one rule,
to match the device for which the node will be created.
