Strange problem

[Brett Chance]

My quad stick is having erratic movement  and input.  The lights facing me keeps cycling between the first light (purple) and the second and fourth light (red).

That would be a problem with the USB connection.   2 & 4 indicate the USB just finished making a new connection.

There are an infinite number of possible causes.   Cables, connectors, power supplies, software problems with the host, if a USB converter is involved, it could be something with that.

Thanks for the tip!

I replaced the USB B to A cable. Same thing. I had another Quadstick, but it had the same issue. I've tried multiple ports with no success. All other USB devices work fine. It worked fine for 2 days, but started this in the middle of the day. I was installing several programs at the time, but never opened them. I threw in the towel and hooked my old computer up, and its working fine now. The constant appearance of red lights 2 and 4 are gone.

On a side note, I don't think the pre-owned Quadstick I bought was "unused" as claimed. There's no RAM mount. I think he just took the old one off the mount and forgot to give it the other one. Other than the mouthpiece what else should I sterilize? As to why he sold it, I can't get softs to trigger on the side tube.

There is no separate "soft" sensor.   Each hole has one pressure sensor for sip/puff/hard/soft/short/long.  Everything else is software.  When a soft input is not being used, it does not make any sound in the soft range.

It sounds like your new PC is either aggressively trying to save power by suspending the quadstick's flash drive, or some software is scanning the flash drive.  Both can be addressed by disabling the flash drive.

Try using Mouse2 no flash, which will disable the flash drive while it is being used.  If that stops the problem, you can modify your game configurations to also turn off the flash.

Finally, there is a long standing problem with the Intel DSA service that affects some computers:  https://groups.google.com/g/quadstick/c/jAsvUQUMVn4/m/rncP3v3pAAAJ
