Very strange - but my 940 is no longer recognised as a USB device by my PC. The light on the TT turns green for a split second , then red and the PC reports an unrecognised USB device . I have tried other USB ports on the same machine and the TT cradle on another PC - all with the same results. As far as I can tell the TT charges from the cradle in the car .
The only thing I can think of is I've damaged the pins on the cradle when cleaning it - but I can't see any damage.
Any ideas ?

Have you tried resetting the unit and trying again? Not sure whether your model has a dedicated reset hole or if you need to hold the power button about 10 seconds till the drum sound is heard.

You beat me to it! Rolling Eyes

This happens sometimes when I connect my 720 to the PC, and I've always found that a pin in the reset hole sorts it out.

Problem solved ... sorry
I tried removing the micro SD card , shut down , reboot , shut down , insert , place in cradle , reboot. The first time I did this - no change. But the second time - the PC recognised the TT. The light is still red however - does this mean its not charging .
Grrrr................ TT software again .................

Red DOES mean it's charging....

Green means it's charged.

If you have problems again, try the steps in the THIRD section here.
