simple udev rule not working

simple udev rule not working

[Mark Eaton]

I am trying to get a simple udev rule to work with no luck. Could somebody shed some light on what I am doing wrong. I am using 2.6.1 with udev 014.

I have the rule

LABEL, BUS="usb", SYSFS_serial="NA0120307040254530 ", NAME="epson915"

if I do a hexdump on the serial it has a space at the end, but I have tried the rule with and without the space and it makes no difference.

The following is the sysfs tree of relevance to the device

.

|   |-- bInterfaceNumber

|   |-- detach_state
|   |-- iInterface
|   `-- power
|       `-- state
|-- 2-1
|   |-- 2-1:1.0 /*
/* Other usb port */
|-- 2-2
|   |-- 2-2.1
|   |   |-- 2-2.1:1.0
|   |   |   |-- bAlternateSetting

Ok I realised that this is now in the 015 release of udev where the 
interesting details are in the parent directories of sysfs. so please ignore 
the last post.

Please use version 015, it should fix this problem.

If not, please run udevinfo the device you are trying to name:
	udevinfo -a /sys/whatever_trying_to_name

thanks,
