T630 on T28 and SEMC 8.4

When i plug the cable in, the phone powers up automatically .. and then if i press the power button it switches off. I cant power the phone up with the power button if the phone is connected to the cable. I must disconnect the cable and switch on, or just plug the cable in and it powers up.
I downloaded Floats Mobile Agent to check i can get a connection to the phone, and when i turn the Mobile Agent on, with phone connected, it recognises the phone correctly. Wierd :)
