 samsung android usb driver, unknow device, usb device disconnect constantly

MTU usb driver, not installed properly.


Samsung OEM micro usb cable is the ultimate cause,  when you move or touch the cable around, it get disconnected, device manger constantly refreshing, constantly scan for hardware change.

Replace Samsung  OEM micro usb cable with any other brand will fix all problem.


==========================================================

For my HP Desktop.


1) repeat press F10 when power on, get into BIOS configure.

2) on top menu - advanced  - device option - USB 3.0 support (enable it), default is disabled.




3) sometime device manager refresh scan for hardware change, then unknow device,

this is because windows install driver from windows update, should disable it, should let windows install driver from samsung driver folder only,

Disable Searching Windows Update for Device Drivers

1. Click Start, right-click Computer, and then click Properties.
2. In the Tasks list, click Advanced System Settings.
3. On the System Properties dialog box, click the Hardware tab, and then click Windows Update Driver Settings.
4. Select Never check for drivers when I connect a device.
5. Click OK twice, and then close the System dialog box.

I believe this is the real cause for all trouble, such as MTU usb driver not installed properly, samsung android device not recognized by PC,  android usb device constantly disconnect and reconnect and failed to recognized. etc.....





--------------------------

if you use android simulator, must enable bios vt-x visualation technology from bios

bios - security - system security - visualation technology - enable.










below are try may not be the cause.

=====================================================



try:

1) remove previously installed blue tooth usb device. (or SD card), they may be the problem.


2) remove google androic studio ( maybe problem )

3) unplug internet. ( I see samsung continuing removed add, remove add, not sure if computer keep removing hardware)

This fixed ALL my USB 3.0 issues. Not mentioned anywhere else!

Its a BIOS ISSUE. Hopefully your computer has this option.

Go into your BIOS and TURN OFF "Legacy USB Support".

If you want even more speed, (there is a catch), Switch from "quick remove" to Buffering. BUT YOU HAVE TO DISCONNECT THE DRIVE WITH THE REMOVE USB DEVICE OR POWER DOWN THE COMPUTER FIRST.
