USB connection fails until watch is switched off/on

This issue occurs with a beta version 27.05 and I posted it on the beta forum. However I'd like to know if this is seen with 26.08 and earlier as well. Is this familiar to anyone?

I have a number of Garmin devices that are used with a Linux system to transfer files from them. Never any problems until 27.05 on the Forerunner 955, it keeps disconnecting. Changed cable, port, rebooted laptop, nothing worked until I switch the Forerunner off and on. This happened twice on different days. The restart is a workable solution but less than ideal. Fenix 5 and 6 work normally with the same laptop. 
There are no dumps or errorlogs on the Forerunner that list anything that might be related.
