FC2 How is usb (device,bus) mapped to /dev ?

I have a FC2 machine with several scsi drives. I find that if a usb zip drive is plugged into the same usb port on the machine then rebooting the machine (with various other configurations of usb stuff plugged-in, such as thumb drives) changes the /dev associated with that port. So sometimes it must be mounted as /dev/sdg4 and sometimes as /dev/sdf4.

Is there a way to look at the output of /sbin/lsusb and tell from the (device number,bus number) pair which /dev the the listed item (such as iomega zip) will be associated with? What is the fastest way to figure out which /dev I need to use in the mount command?

Use the the command ' fdisk -l '. From that you should be able to see which sd* it is using by looking at media size. You can specify which sd* a drive will use but its been a while since I worked with that. This means you can always define your zip drive as /dev/sdh* or whatever. There should be some help over at www.linuxquestions.org
