I'm trying to set up 1-wire on my Ubuntu. It needs a usb port to be associated with a device. The instructions say to run lsusb to see your usb's. Then run dmesg to see which device the usb is attached to. The example output of dmesg says "usb 2-1: FTDI USB Serial Device converter now attached to ttyUSB0". My trouble is I'm not getting any indication what device my usb is attached to. Nowhere in the dmesg output am I seeing "...attached to..." How can I find this out?
