So this is weird. I tried it with _my_ random USB mouse, and it works 
fine. It's my custom HID device that breaks it. Joystick also seemed to 
work fine. I wonder if it's somehow related to devices which only show 
up as hidraw devices (ie: they don't also show up as /dev/js or /dev/mouse.)

I re-configured my programmable USB device (PIC32 USB Starter Board) to 
be a mouse, and it works fine. When I configure it to be my custom HID 
device, I get the problems.
