reading mouse mode from unopen file descriptor hangs mouse driver
I'm writing a program to control the mouse. I ran it with the mouse daemon still running; it output -1 for the file descriptor and nonsense for the protocol. I stopped moused and tried again. Same result, except a slightly different nonsense protocol number. I ran moused again and it refused to start.
Version is v18.104.22.1684.g7bf41-DEVELOPMENT. Mouse hardware is PS2, with a scrollwheel, which I'm trying to get to work.
