I have two USB devices that work as serial ports: ugen2.2.0: umodem0: <Hokuyo Data Flex for USB URG-Series USB Driver, class 2/0, rev 2.00/1.00, addr 2> ugen2.3.0: uplcom0: <Prolific Technology Inc. USB-Serial Controller, class 0/0, rev 1.10/3.00, addr 3> and they appear as serial devices /dev/cuaU0 and /dev/cuaU1. But I can't find a general-purpose way to figure out which is which. It depends on which gets enumerated first. In FreeBSD 7, the USB device minor # seemed to correspond to the cuaU device number, but here they are both zero. Any ideas? -- Trevor Blackwell tlb@anybots.com 650 776 7870
