Logitech G920 died??

[scrw.]

Was working fine at lunchtime. Just fired up the PC and it is not seen at all in devices/device manager and doesn't do the usual calibration spins, all I get is a fash flashing LED by the xbox button. All cables reseated, sockets tested, different USB port tried but nothing. Just about to test the power from the power lead but any other suggestions?

TIA

Well I am getting 23.8v from the power lead, 24v is listed on the block so expect this is okay, googling has found nothing usefull.
