Intermittent USB Connection Issues with TomTom 4fl60 on macOS: Seeking Diagnostic Advice

[fsfarimani]

I'm experiencing issues with updating my TomTom 4fl60 GPS device. While I can't connect it to any of my Windows PCs (despite trying multiple cables, including the original), I can connect it to my MacBook running macOS. However, the connection drops every 20 minutes or so during updates. I want to diagnose the problem using the bash terminal on macOS. How can I monitor the USB connection stability and identify the cause of these interruptions? Any guidance on specific commands or logs to check would be greatly appreciated.

Maybe it's the mini socket on the GPS side that has a problem?
Have you tried wiggling the cable plug?
