In the worst case, check the board:
In general, USB connection stability / reliability issues is likely caused by one of these on FW 11th gen boards:
- USB voltage
- EMI shield
- Cable quality
- Melted chip
- Driver
- Heat
I don’t think there’s any reports of the melting situation on 12th gen nor 13th gen boards. So it seems like it’s a 11th gen board behaviour (i.e. design changed since 12th gen to address it), or the melted ICs are from a batch with higher than expected failure rate. It’s also not clear if the melted IC sutiation is bad luck or a matter of eventuality or in combination with poor cable / compatibility / 3rd device…
