Corrigir Problemas de Conexão USB
Solucione problemas comuns de USB incluindo dispositivo não reconhecido, transferências lentas e desconexões intermitentes.
1
Try a different USB port
Test with a USB port directly on your computer, not through a hub. Try both USB 2.0 (black) and 3.0 (blue) ports.
2
Check the USB cable
Swap cables if possible. Damaged or low-quality cables are the most common cause of USB issues.
3
Update USB drivers
Windows: Device Manager > Universal Serial Bus controllers > Update driver for each entry.
4
Disable USB selective suspend
Power Options > Change plan settings > Advanced > USB settings > Disable selective suspend.
5
Check Disk Management
If a USB drive doesn't show in Explorer, open Disk Management (diskmgmt.msc) to assign a drive letter.
6
Test on another computer
If the device works elsewhere, the issue is likely drivers or USB controller on your computer.
