mount USB devices, sda, manually/statically assign sda?

Oxyacetylene · 12-20-2004, 01:09 PM

Is there a way to manually assign what each USB storage device will be recognized as? I have 3 different USB storage devices (USB hard drive, digital camera, USB pen drive) and whichever one I hook up first becomes sda1, second becomes sda2, etc.

I would like to have it set up so that each device always shows up the same so I can mount them in specific locations:

for example: make usb pen drive always sda3, camera sda2, usb hard drive sda1.

How do I set this up?

Take a look at this howto:

that may work, but I also might hook up two of the same vendor's usb pen drives. Is there another identifier I could use other than the vendor? Is there a serial number for these things?

Actually, there is. You can look at it in /proc/scsi/usb-storage-X, where is X is the number of the USB storage device attached (in order, I presume)

The output from mine:

Code:
