The UHK 60 v1 connects to the host computer via a Mini-B USB connector. (Part number: 548190519)
This connector might get loose over time in which case you can try to fix it by disassembling the right half of your UHK to access the top side of the USB connector.
Then you'll see three metal tabs on the top side of the connector. Make sure to unplug the USB cable, then bend the tabs slightly downward.
