DA V2 X hyperspeed not detected by synapse and works occasionally

tested with mouse tester, results showing left/right clicks, side buttons and dpi buttons only registering after pressing several consecutive presses, cursor moves to top left at a constant slow speed.

 

Pressing the keys used to turn on the pairing mode don’t work.

 

Using a replacement 2.4GHz dongle doesn’t get the mouse recognised by the synapse app but does get recognised by firmware update utility and 2.4GHz pairing utility.
