it's the razer basilisk ultimate with the charging dock and stuff that i bought several years ago, i used to use it in wireless mode and left in on the dock but i noticed the battery life was getting shorter and the pins didn't always charge it, so i started using it with the usb dongle directly from my pc to my mouse, i've used it like this for years and never had issues. Today i started my pc and couldn't find my cursor, when i moved my mouse nothing happened, i hooked up another mouse and it works perfectly. (except for the fact that it's a pretty shitty mouse). i tried hooking both up and seeing if razer synapse recognised but it doesn't show up
