If you're using full-blown devfs and usbdevfs, then USB serial ports should appear as /dev/usb/tts/0, /dev/usb/tts/1 and so on. Otherwise you'd need to have device nodes for them. I think Redhat by default still doesn't use devfs (not sure why not though, I tend to regard it as the best thing since sliced bread, the only thing it seems to break is kudzu, which it renders largely un-necessary) so instead you would probably have a series of possibly-usable device nodes already sitting around named "/dev/usb/ttyUSB0" and so on. Without devfs there is no simple way to tell which (if any) of these device nodes correspond to actual devices, but probably if you just have one single-port USB serial adaptor it would be ttyUSB0.I have similiar problem. I bought a usb to serial adpter. How do I find it out which device it is? I am trying to get minicom to use this connection.
If you're sure that USB support is working, but you don't find any (working) device nodes for your serial adaptors, this probably means that you're using unsupported adaptors (may be worth looking for new drivers and/or downloading a new kernel). I personally use "IO Gear" brand, but this is mainly because I could get them quickly, cheaply and in quantity. I was however quite impressed by the fact that the very first time I plugged one of them into a machine (which was on at the time, running Redhat 7.1 with devfs and usbdevfs) the adaptor was detected and working within about 1.5 seconds. This suggests that hotplug really does work ;)
