I've had my DeathAdder for about seven months now, and it's only now causing unbearable issues. The mouse will either work or not work when booting Windows, Synapse doesn't even pick up the device when re-plugging it, and when using Linux the cursor will randomly fly up in the top right corner. I can't seem to find any information about this (or a fix) and Razer support won't help because it was a gift.

Has anyone had this issue? If so, how did you go about fixing it?
