Anybody - greetings:
I have been trying to get a .rules file to work to rename my Shuttle device.
BUS=="USB", SYSFS{idProduct}=="0020", SYSFS{idVendor}=="0b33", MODE="660",
GROUP="plugdev"
works fine. Device appears in /dev/input as mouse2 but with correct plugdev
Group.
If I change the .rules file to
BUS=="USB", SYSFS{idProduct}=="0020", SYSFS{idVendor}=="0b33", MODE="660",
GROUP="plugdev", NAME="xpress"
then the line seems to be ignored as device comes as mouse2 and group is
root (as per default with no rule).
I have tried lots of different positions in the line for NAME= - everything
seems to make the line be invalid (ignored).
(a) It it illegal to name a USB device like this?
(b) Where might I expect to find the error logged (if anywhere)?
I can get away with the long name from the driver in /proc/bus/input/devices
as I currently only have one device (a lathe would be good with two - one
day)

I get that far but will have to do more work on my (very basic) Python
skills to get it all running in context of EMC so I can see the events.
As a really crude approach I have tried some "print"s in the hal_input
update() method. Early tests suggest that the kernel driver (thinking
device is a mouse) is giving funny events. But it needs some more testing
(and research on what the kernel usb drivers do) :=)
