Hello,
I’m trying to connect via USB my FP3 to my pc (Windows 10 OS), but the system says me “unrecognized usb device”.
I already activate debug USB option form developer menu and changed the USB transfer option to PTP.
First, make sure you use a data cable, there are USB cables out there only for charging, and they will not work for data.
Second, I guess most people would want to connect via MTP to see their files.
When I had trouble with MTP on Windows 10, I did the following to get old phone or MTP stuff in the system out of the way …
Disconnected the phone from the computer.
In Control Panel - Programs and Features:
Uninstalled everything with “MTP” or “ADB” in its name.
Rebooted Windows.
In Control Panel - Device Manager:
Enabled View - Show hidden devices, and then uninstalled every possible ADB, MTP and smartphone device, hidden or not.
Rebooted Windows.
Connected the phone again, Windows then needed a moment to set up MTP again automatically and prompted a success message afterwards.
