I have a Nuvi 2455 that worked great for years. My Windows 11 computer will not recognize the Nuvi 2455. Basecamp & Garmin express work fine. It shows that I need updates for the GPS but it can't be viewed on the computer.
The following updates were installed on the computer:

I have used Windows 11 with no issues for years and sometime between Dec 025 & March 2026 something changed & windows will not recognize garmin devices. I have tried all fixes I could find; check for system errors, power settings, different cables, different computers, but none will now see the device. I can't update maps or system updates.
Looking for any suggestions to make system usable so I can upload maps to my devices
