[tlug] Mythbuntu 9.04 rejecting Android USB connection

[Dave M G <dave@example.com>]

TLUG,

My Android phone connects via USB to two of my three computers without 
any problems.

However, on one computer, when it attempts to connect, it immediately 
disconnects again. Further, after I make an attempt to connect on this 
one computer, that sours the Android for making connections on the other 
computers. I have to reset the Android phone's USB* in order to get it 
to play again.

Because two out of the three computers are doing okay, I'm assuming that 
the problem is on the one machine. It is running Mythbuntu 9.04.

Here is the output of dmesg when I attempt to mount the Android device:

[113089.959053] sd 3:0:0:0: [sdb] Device not ready: Sense Key : Not 
Ready [current]
[113089.959060] sd 3:0:0:0: [sdb] Device not ready: Add. Sense: Medium 
not present
[113089.959066] end_request: I/O error, dev sdb, sector 0
[113089.959086]  unable to read partition table

What might the computer be doing that is not only rejecting a 
connection, but also sending a signal to the Android that leaves it 
slightly malfunctioning?

Any advice greatly appreciated.


*Android USB connection fix: Settings->Applications->Development. 
Checking and/or unchecking the USB debugging box seems to rest the USB 
connection.
