[Xiaomi Mi A2] UBports Installer 'ADB is scanning for devices'

[scienz]

Hello,

so I went through the installion process on the UBports Installer until it says boot to recovery. The phone does boot to the Ubuntu Touch recovery but the UBports Installer can't find the device anymore.

What am I doing now?

BTW, it is the second time I'm landing at the same point.

OK, after rebooting I had to reinstall the ADB driver in Windows.
The UBports Installer now recognized the phone and started sending files to the device. But it takes very long, already over 30 minutes.
