Jens,
I don't believe there is any way the software can control the power to the HOST USB C port where your GPS Dongle should be plugged into. I believe that USB power is a directly wired connection to the internal power.
The GPS functioning was one of the first things I checked on my X6100 after the patch, to verify I could get the X6100 system time to sync with GPS time. FT8 requires the system time to be within a second or two of the same time as the other stations, or FT8 won't decode the received stations.
My GPS Dongle connects to the X6100 with a USB C to USB A adapter. Both the adapter and the GPS Dongle have LED power lights on them to indicate that they are receiving power from the X6100 HOST USB C port. I just checked again, and both lights are on when I turn on the X6100. The only time the lights didn't come on was when I plug the adapter/dongle into the DEV USB C port instead of the HOST USB C port, so make sure you are using the HOST (bottom) port.
The X6100 system time syncs with my GPS dongle time, after the GPS starts sending GPS times to the X6100. I verified that by making sure the day, month, year and hours were set up to the GPS time, but changing the minutes to something other than the GPS time. After turning on the X6100 and the GPS started sending time, the system time synced with the GPS time correctly.
So on my system, at least, the GPS seems to be working correctly.
