Re: [Thinstation-developer] Re: udev PROGRAM action

[Miles Roper <mroper@xtra.co.nz>]

Hi Kay,

Thanks very much for your help so far.  Its starting to make sense :o)

I still can't get the below rule to work :o(

KERNEL="sd*", ACTION="add", BUS="usb", RUN=+"/etc/udev/scripts/usb.sh"
KERNEL="sd*", ACTION="remove", BUS="usb", RUN=+"/etc/udev/scripts/usb.sh"

neither script gets run (as they create a test file in /tmp if they run)

I can post info from syslog when the device is added if you want?

Thanks

Miles
