I have a Deathadder V2 Pro and Deathstalker V2 Pro TKL. The dongle of the latter doesn't work anymore. When I plug it: it's connected, then disconnected, connected, disconnected and so forth. I already used other USB-ports, but the same thing happens repeatedly.
I can use the DA dongle for both mouse and keyboard, but I can't update the firmware of the DS without the original dongle working properly. Can you please help me with this issue.
