Using a USB Keyboard and Barcode Scanner on a Mini .. not working.

I have tried multiple keyboards, and Im using a Zebra DS22 hand scanner. Whenever I connect both these devices to a Clover Mini, the android soft keyboard always appears. The mini is not tethered to a station it's in standalone mode.
Here's what I've tried so far.
If I disconnect the scanner the usb keyboard will work fine.
I have 2 Clover Stations, and the problem does not occur with these, I also have a Station 2018 and both devices work simultaneously with this device also.
It doesn't matter which USB ports I connect to, nor does the order in which I connect them.
I've rebooted several times, at various stages of the above attempts to get this working.
If I have the Android Settings > Language & input settings, without the scanner attached I can select USB keyboard. If I then connect the scanner, the option to select/deselect the keyboard remains available, however as soon as I close this option screen, and go back into it, I can no longer select USB keyboard.
Any ideas?

BTW even though the soft keyboard always appears, I CAN still use the USB keyboard. So neither device is disabled by having them both connected, but the soft keyboard appears anytime there is an input field, so of course has to be closed.

I don't know if the Zebra DS22 is a supported Clover scanner. It's not listed but sometimes it's a submodel of something that is. I can't tell for sure until you give me the USB vendor, product ID.

I was able to reproduce I think what you see. I connected a hard keyboard and this will prevent the soft keyboard. I then connected a supported scanner (IDTECH) and the soft keyboard is no longer suppressed. Worse it looks like connecting the scanner causes the settings for the hard keyboard to not be accessible.

I'll file an internal issue to fix this. I can't give an ETA though.
