Bluetooth Problem IOGear Dongle

[NeptosMP]

I bought the Bluetooth 4.0 USB Micro Adapter GBU521 for my hackintosh. Now here comes the strange part: On 10.12.5 I plugged it in and it worked. Then I updated to High Sierra and now it only shows the MX Master. No other keyboard or mouse. I tried removing the on board WIfI/B. chip, a reset of the dongle, activate using Bluetooth Explorer etc. Nothing worked. Do you have any advice to fix this?

Please let me know if you need more information.

Thanks

@VioletDragon I saw in an other tread you said it's about a USB mess. I think that's maybe the answer because I have some trouble with that. If you're willing to help me please let me know if you need something.
