I want to thank Alan for his reply, and I thought that with this info I had
it nailed, but no. When I look down in /sys bInterfaceClass is there, but
when I do (ala the UDEV Instructions)

[EMAIL PROTECTED] reg]# udevinfo -q path -n /dev/sda
/block/sda
[EMAIL PROTECTED] reg]# udevinfo -a -p /block/sda
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.
looking at class device '/sys/block/sda':
SYSFS{dev}="8:0"
SYSFS{range}="16"
SYSFS{removable}="1"
SYSFS{size}="2015232"
SYSFS{stat}=" 6 17 184 161 0 0
0 0 0 161 161"
follow the class device's "device"
looking at the device chain at '/sys/devices/pci0000:00/0000:00:0d.2/usb1/1-5
/1-5:1.0/host7/target7:0:0/7:0:0:0':
BUS="scsi"
ID="7:0:0:0"
SYSFS{device_blocked}="0"
SYSFS{iocounterbits}="32"
SYSFS{iodone_cnt}="0x4ed"
SYSFS{ioerr_cnt}="0x2"
SYSFS{iorequest_cnt}="0x4ed"
SYSFS{max_sectors}="240"

I dont see it listed.
And from the instructions my understanding is that if I dont see it here
I cant use it (sigh).
So the obvious question, what am I doing wrong?
