No ADB connection to Transformer Prime TF201 on 4.1.1 ADB connection to Transformer Prime TF201 on 4.1.1

With USB Debugging disabled I can see the TF as expected.

With USB Debugging enabled I can see an entry under Device Manager for ASUS Transformer Prime ADB Interface with no warnings or errors. However when I attempt to use ADB to connect I'm not getting any devices returned.

Screenshot here:



If I plug my phone in and list devices I get a single entry returned which works as expected, SHELL etc works normally.

Any thoughts?
This was an issue with the computer I was running ADB on. I took the transformer to work and ADB worked perfectly first time.
