The current kernel is buggy, so USB hotplugging does not work. You need to have the stuff inserted at boot time for it to be detected.If you need hotplugging, then a hub inbetween (which is never unplugged) is a workaround. If the adapter is unplugged, then it wont be detected again, but since your adapter is detected, I do not think this is Your problem. Offered TI to fix this, but they say that a fix is in the works, but have no clue when. I use Angstrom which will provide /dev/ttyUSB0 when inserted at boot time. Which linux are you using? /ulf > Richard -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
