Hey,
I have a similar issue with the QHY5III 462 color cam. I can't connect it in kstars.
When using lsusb I get the following output:
Bus 005 Device 006: ID 1618:0462 Cypress WestBridge
So the camera is visible. However running the test /usr/bin/qhy_ccd_test gives:

No QHYCCD camera found, please check USB or power.

The SDK is (sudo ldd /usr/bin/indi_qhy_ccd |grep libqhy*):
libqhyccd.so.22 => /lib/aarch64-linux-gnu/libqhyccd.so.22 (0x0000ffff94e18000)

I built kstars and indi including indi 3rdparty drivers from source just 2 days ago.
I tried running sudo apt-get update && sudo apt-get -y dist-upgrade but I still got the same error when running /usr/bin/qhy_ccd_test. Trying different USB cables and both USB3.0 and USB2.0 also didn't work, so they don't seem to be the source of the issue. At this point I don't know how to find/solve the issue..
My ToupCam IMX571 color CCD and EQMod mount run perfectly in kstars.

If "lsusb" shows "Cypress" and not "QHYCCD" then that probably means the firmware wasn't loaded. Unfortunately, the fxload utility that's packaged is out of date. You must download and build one that supports newer USB3 cameras from

sourceforge.net/projects/fx3load/

After you build it, copy it to /sbin/fxload, and either unplug/replug the camera, or reboot

That is correct, however it is the OS that has the wrong FXLoad in the distribution (most ubuntu 20.04 have the USB2 versions) The Beta GITHUB INDI 3rdparty distribution has the correct FXLOAD (FX3) now. The next update to the standard INDI driver should have the correct FXLoad.

But yes, he is quite correct, you can build and install FX3 version on his link.

I downloaded the fx3load package, however I was not able to build it due to my limited linux knowledge. So I decided to just download the SDK library directly from qhy and follow their instructions: www.qhyccd.com/html/prepub/log_en.html#!log_en.md . I ran the "sudo bash distclean.sh" to get rid of the old one and then installed the new one with "sudo bash install.sh".
Now when running "lsusb" the camera was detected correctly: Bus 006 Device 002: ID 1618:0463 QHYCCD QHY5III462-211011.
However when running the test script "/usr/bin/qhy_ccd_test" I got the error: "libqhyccd.so.22: cannot open shared object file: No such file or directory".
So I just copied the missing file from the one which I still had from the build directory: "sudo cp ~/Projects/build/indi-3rdparty-libs/libqhy/libqhyccd.so.22 /lib/aarch64-linux-gnu/"
Now the camera works perfectly in kstars.

Thank you guys for helping me out here.

This issue has appeared again. After a recent update my QHY5iii462C shows up as 'Cypress Westbridge', suggesting that the firmware is not loading.

Did the newest version of INDI 3rdparty lose the correct FXLOAD recently?

Might be, I had the same issue and had to re-compile FX3LOAD for my platform X64 on Ubuntu.

How to compile fxload please ?
No issue with V3.6.2 beta.

It's already included with StellarMate. no need to compile there.

I was hoping it would be as easy as following Kevin Ross' lead and replacing fxload in /sbin I can now see the QHY5iii462C in lsusb and it is successful with QHY's LiveFrameMode test program, but in KStars the QHY driver crashes immediately.

Running $indiserver indi_qhy_ccd fails due to missing libqhyccd.so.22 (as per Simon's post above)

Can I get libqhyccd.so.22 somewhere without building INDI-3rdParty from source?

[edit]: Going backwards. I installed nightly and rebooted - and now I'm back to "Cypress WestBridge" in lsusb. Copied the fxload from fx3load over to /sbin again but still not seeing the camera, jusy Cypress WestBridge

The issue doesn't exist with V3.6.2 beta, only with V3.6.3. One tells me to install libusb-dev and compile fxload. Wih no success. I am unable to connect my QHY camera, 294C and 224C. So I can't image the comet ZTF !
