Windows 7: USB ports problem - seeing unidentified devices, disconnecting mouse

USB ports problem - seeing unidentified devices, disconnecting mouse

I have Logitech Performance MX mouse. It used to work fine until somebody installed other mouse on my computer. Since then mouse was randomly disconnectign and reconnecting every minute.

I managed to fix that now mouse is stabile but even though all drivers are installed it is seen as HID mouse and not my Performance mouse - so i cannot for example see its level of batter load.

The other problem is there is loads of extra identified USB controlers and mouses even tho i have just connected 1 mouse, 1 keyboard by other USB port + 1 external HDD. Thats just 3 USB slots total.

If i put pendrive into computer, then mouse keeps disconnecting again.
If i turn on 'shield scannign devices' then after puttign USB into drive i have 3 seconds to click 'not scan it' if i do that, it wont be disconnecting. Yet turning off scanning makes mouse disconnecting on putting extra pendrives.

Here is what i tried so far:
@ USB Driver - General Fix for Problems [after reboot everything comes back gryed out, again 10s of mouses]
@ Turning off windows shell scan [to not auto scan devices].
@ Chaning ports, upgrading bios etc.
@ RUnning windows 7 USB problem fixer. It is turning off upper and lower shell that sometimes seem to help but after reboot all gets back to original state.

Here is screens of my drivers/devices:

All drivers are updated.

This is very annoying.

1 morei nterestign thing:
if i put USB pendrive to any usb port mouse will disconnect and be 'unknown device' but if i put pendrive to USB 3.0 port [port where i never installed anything] it will work.

is there any way to fully reset all USB port setups and make them clear? i have jusm ouse keyboard and hdd. and it seems some reg file stored corrupted data and it cannot be uninstalled in device manager.
