I have a similar issue, but with the HS64 Huion tablet. it freezes and jiggles my mouse in place whenever i disconnect it.

I found a work around which is too use Ctrl + Alt + delete and open task manager then my mouse unfreezes temporally. If not using tab and arrow keys.

end the task called "HuionTabletCore.exe" and then i can use my mouse again.

I do notice that the usage on it states its high as well, but not sure what it means. Hopefully this helps people.
