But probably the most expedient way would be to tail dmesg, like so: $ dmesg | tail There is a way to get tail to "loop" so it stays running while you hotplug devices,, etc, but I do not recall what the command switch is off hand. Maybe -f, I'm not sure. Anyway, here is the point. run the command above without the device plugged in. Plus the device in, then run the command again, and see what's changed. It should say something about the mrusb blah blah, then givesome information on your USB device. Another way, would be to ls in the dev directory, and look at all the tty entries. What you'll be looking for is ttyUSB, or ttyACM. Typically, what you're looking for will stand out, and if you only have one serial adapter connected, you'll only see one like it. There are other ways too, which are too complicated to get into. But sometimes you can find information about your device by looking through the /sys sysfs file structure. For this case, that should not be necessary. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
