custom names for each slot in a multislot usb reader

custom names for each slot in a multislot usb reader

[Samuel Liddicott]

I have a multislot usb reader that gets assigned sda,sdb,sdc,sdd as the 
main block devices.

I can't work out what rules I need so that sdc becomes /dev/mmc and sdd 
becomes /dev/smartmedia etc

Now I can do rules to match the device and /dev/hda - but this will only 
work if my other usb thumbrive isn't handled first.

So I really need a rule to match on LUN.

Try:
  udevinfo -a -p /block/sda
  udevinfo -a -p /block/sdb
  ...

You will find keys here that are different for every slot, but
independent of the kernel enumeration. I have one reader that already
has names for the slot one other has numerical id's to match.

Thanks

Based on that advice, these rules work:

BUS="scsi" SYSFS{model}="Flash XL      CF" SYSFS{vendor}="Medion*" 
NAME{all_partitions}="media/compactflash"

BUS="scsi" SYSFS{model}="Flash XL      MS" SYSFS{vendor}="Medion*" 
NAME{all_partitions}="media/memorystick"

BUS="scsi" SYSFS{model}="Flash XL  MMC/SD" SYSFS{vendor}="Medion*" 
NAME{all_partitions}="media/securedigital"

BUS="scsi" SYSFS{model}="Flash XL      SM" SYSFS{vendor}="Medion*" 
NAME{all_partitions}="media/smartmedia"
