Usb Vid 1f3a&pid Efe8&rev 02 3 Driver May 2026

If you have successfully resolved this error, your device will typically enumerate as multiple child devices: a modem, an AT serial port, a GPS port, and a network adapter. Once those appear, your 4G/5G connectivity is ready for action. Have a different PID or REV code? The same logic applies: check the Vendor ID (VID) first. If it’s 1F3A , it’s ZTE. Search for ZTE modem drivers, not generic "USB drivers."
