VEMS Bluetooth adapter. Ongoing issue ............ I have twobluetooth adapters and both do the same!! Previous error reports back in 2013 never resolved the comms issue ( not of concern here) with the first adapter so I bought another. When the adapter is powered on for the first time after long period of power off ( a couple of hours at least), the bluetooth adapter will not come to life! (No LED). Unplug and re plug, the adapter comes to life and works perfectly with repeated power on and off until left powered off for a few hours...... We start all over again. I can recreate this time and time again, either with Dsub Pin 9 power, or external USB power. External power is by top quality USB cable and tested on Dell PC USB port, 2amp mains power adapter or 1amp Car type USB charger, same issue with all.
