2.6 PCMCIA/USB question

2.6 PCMCIA/USB question

[Joerg Pommnitz]

Hello all,
I have a question that I could not figure out from other sources. I have
the following hardware: an integrated CardBus USB host adapter with a
connected USB serial device with three interfaces (normally
ttyUSB0...ttyUSB2). Now I want to use 3 of these devices (remember: they
are integrated, so I can't just plug the USB device onto the same host
adapter). I know device A is in CardBus slot 1, device B is in CardBus
slot 2 and so on. 

Now the question: How do I figure out which ttyUSBx belongs to which
device?

Thanks in advance
  Joerg

Trial and error (and hope they are always the same, which I think they
are with 2.6).

You can look in the system log.  If you want, you can actually control 
which goes where by creating a udev configuration file.
