Got a new DeathAdder V4 Pro today which works when connected directly to my PC but not through the wireless dongle. When the mouse is turned on and the dongle is connected to the PC, the LEDs on the dongle remain off and the mouse’s LED flashes twice when it is moved. I cannot get the LEDs on the dongle to turn on at all. I have tried:
- Fully charging the mouse
- Connecting to another PC. Same issue occurs
- Updating firmware of the mouse and dongle to 1.20.00. No change
- Pairing the dongle using the mouse pairing utility. It recognizes when the mouse and dongle are connected and says pairing is successful however it still doesn’t work
- Removing and reinstalling drivers using the device detection troubleshoot tool. This did not change anything
- Uninstalling/reinstalling Synapse 4. This also did not change anything. Synapse can configure the mouse when it is directly connected to the PC, however when the dongle is connected and the mouse is turned on wirelessly, Synapse says the device is switched off. The situation is the same when synapse is not installed.

Seeing as both the mouse and dongle are separately detected I’m not sure if I’m doing something wrong? Has anyone else had this problem?
