yes, it appears as /dev/sda*

I have working udev rules and eg one key shows up as 
/dev/pny* just fine and in /etc/mtab as /dev/pny*, which is 
what I want (usb harddrives appear as /dev/backup* etc). 
However in /proc/partitions or /proc/diskstats it's 
/dev/sda*. I'm logging disk read/writes etc through 
/proc/diskstates, so I want to know which usb drive is
plugged in, rather than the arbitary sd[a..z]* device.

While dmesg is fine for watching the device being plugged 
in, it doesn't help in 2hrs when a script is trying to 
figure out which external devices are doing what disk 
activity.

lsusb doesn't tell me anything about the scsi device 
(/dev/pny* or /dev/sda*)

systool doesn't help either (AFAICT)


Thanks Joe
