I was attempting to to use android's adb toolbut when I enable usb
debugging on my phoneit appears to repeatedly detach/reattach the device.
Anyone experience this before or have any advice on how to debug this?
Here's the output of /var/log/messages with some usb debugging enabled
and ugendebug set to 0xffff
First connecting with usb debugging disabled

Then I enabled usb debugging on the phone. It appears to set up a
second interface on device (ifaceno 1) and then detaches immediately
afterwards.

Device appears to re-attach here, add all interfaces and then detach
again. The cycle continues until I unplug my phone.
