setting up android gingerbread on the bone

I'm following the steps outlined at
to install gingerbread on my beagle bone (which has a dvi cape
installed). the card created with no problems. on my ubuntu host I'm
having difficulty getting a serial console set up after connecting the
bone usb and doing the following:

$ sudo modprobe ftdi_sio vendor=0x0403 product=0xa6d0
$ minicom -D /dev/`dmesg | grep FTDI | grep "now attached to" | tail
-n 1 | awk '{ print $NF }'`

the last line gives an error /dev/ttyUSB0 Device or resource busy.

How can I tell why it's busy and what is making it busy so as to
correct the problem?



You could try

dmesg | grep ttyUSB

it should give you some clue.

or you could try more complex solution, which is described here:
