Razer Deathadder V2 Pro

Hello, I have bought a new Deathadder V2 Pro, I already had a Bassilisk wireless mouse with a charging station. So when I plugged in the dongle from that was included with the Deathadder the Bassilisk stopped working, if I use the dongle that came with the Basilisk the Deathadder would stop working. For both of them to work without always having to change the dongle in the loading dock I have to plug in the Deathadder dongle in a usb port and the Bassilisk dongle in the loading dock. Today I got a message saying that the Deathadder needed a firmware update, so I did the update and since then it stopped working wireless, it seems like the dongle from the Deathadder seems to be losing its connection, it makes a noise like when you remove it from the usb port and plug it back in. But I don't pull it out, it's the same with all usb ports on my computer. The only way for the Deathadder to work is to plug it in my computer with the usb cable that was connected to the loading dock. I don't know what to try, do I remove the latest firmware update and if so how do I do this? Any advice is appreciated. Thank you.
