I was using two pl2303 usb rs232 adapters with mythtv as channel-changers and it required some udev rules to ensure that I could get consistent names for each one. Otherwise they are indistinguishable and the kernel doesn't really care how they end up getting named. (I ended up mapping them to physical ports and assigning symlinks accordingly). This sort of thing isn't uncommon with usb. For many users you can definitely get by without udev, but honestly I don't see why you'd want to. It is really nice to be able to use disks based on labels, uuids, and so on. Udev adds a lot of convenience features beyond just giving me a /dev/sda or whatever. Rich
