Indi on RPi 4 and QHY9S-M camera was created by David Allmon

I just switched to a Rapsberry Pi 4 from a Mac Mini and something strange happened. I couldn't keep the camera responding, so I turned on debug and I saw something like:
[2020-07-02T16:29:25.658 MST DEBG ][           org.kde.kstars.indi] - QHY CCD QHY9S-M-140803X : "[DEBUG] Filter current position: 1 "
[2020-07-02T16:29:26.087 MST DEBG ][           org.kde.kstars.indi] - INDI Server:  "2020-07-02T23:29:26: Driver indi_qhy_ccd: QHYCCD|DOWNLOAD_FX2.CPP|fx2_load_vendax|Info: Downloading Vend_ax hex into FX2 RAM"

I didn't think you could update the QHY9S, but it ent something. Now any sequence hangs on "Changing filter" and logs this every second:

2020-07-02T04:56:53: Driver indi_qhy_ccd: QHYCCD|QHYOLDBASE.CPP|GetCFWStatus|GetCFWStatus
2020-07-02T04:56:53: Driver indi_qhy_ccd: QHYCCD|QHYOLDBASE.CPP|GetCFWStatus|cfw status(range 0-n) / number:0

2020-07-02T04:56:53: Driver indi_qhy_ccd: QHYCCD|QHY9S.CPP|GetChipCoolTemp|Begin
2020-07-02T04:56:53: Driver indi_qhy_ccd: QHYCCD|QHY9S.CPP|GetChipCoolPWM|currentPWM = -100
2020-07-02T04:56:53: Driver indi_qhy_ccd: 
2020-07-02T04:56:53: Driver indi_qhy_ccd: QHYCCD|QHY9S.CPP|GetChipCoolPWM|lastPWM = -100
2020-07-02T04:56:53: Driver indi_qhy_ccd:

The driver is waiting on the filter to change from 0 to 1. The QHY9S can't read a filter wheel - it is a one-way, one-wire interface.

Can anyone help me make sense of this?

Problem solved. I reprogrammed my filter wheel to look like a QHY CFW1, installed that Indi driver, and told it to quit using the built-in filter wheel. Now it no longer hangs on the filter wheel. The camera is still wrong, but it doesn't matter.
