Issue: Pinscape Controller prevents PC from sleeping

I can't get my VP to go into sleep mode using the standard Windows 10 setup as soon as the Pinscape Controller (ext. board + power board, TSL1410 plunger) is plugged into USB. With an USB tracer, I see 15 bytes HID packets coming in on the JS interface every 10 milliseconds, resetting Windows' idle timer, effectively preventing sleep. Is this behavior by design? Is this something that could be changed in the firmware?

Yes, the joystick updates are by design. That's just how the Windows USB joystick interface works, I'm afraid; Windows polls incoming packets, so the joystick has to send packets constantly. You can turn it off by disabling the joystick input in the config tool, but if you want plunger or accelerometer input, that's probably not an ideal solution.

You might check to see if you have any third-part software on the Windows side that might be keeping the machine awake. I talked to someone recently who ran into something similar, and it turned out it was a screen saver that was monitoring the joystick. They were able to change a setting in the screen saver to disable that.

Thanks for the quick response. I figured as much already having a quick look at the source code. I tried to kill every process/service to get to a bare minimum, but the machine still wouldn't sleep. I did find a - somewhat dirty - workaround for this problem though: I use an AutoHotKey script to monitor the "Shift" keys and call Windows' suspend (or power off) functions when no key press is detected within x minutes. I'm pasting it here in case it'll help somebody save a few of those hours I spent diagnosing this problem in the future ;-)

...and if that's not it, try a Google search for "joystick Windows sleep" - I suspect you've got something like the above going on.
