There’s a known issue with a recent update causing issues with the white USB port not functioning. I’m still investigating this. Unfortunately I could not introduce a fix in time for the November update. The issue was introduced in August.
You could wait (I don’t have a solid ETA but it’s high priority); or install the 2020.11-1 version (based on Kodi v18.9) which will use an older kernel and not exhibit this issue.
Cheers
