VN7-791G webcam not working

Hi,

My webcam isn't working any more.
I didn't use it for a while and I only found out about it yesterday.

In device manager there is no imaging devices, only one "Unknown USB device (Device descriptor Request Failed)".

I verified this is a webcam when I unplugged it and then plugged it again.

In Events there were entry about driver migration on 2016-09-14, possibly around the same time when Anniversary update was installed (I can't be sure). 

Then, there are these entries 

Device USB\VID_0000&PID_0002\6&16ad8f3&0&5 could not be migrated.

Last Device Instance Id: USB\VID_04B4&PID_00FA\5&1FEEBF0F&0&7
Class Guid: {36FC9E60-C465-11CF-8056-444553540000}

I've tried to uninstall driver, let windows install it again but it didn't help.

I also tried to install driver from acer drivers site but that is for intel and installation can't go through.

I also tried to manually install Cypress USB-Serial MFG mode, because googling for last device instance id was showing it was Cypress. Uninstalling Usb controllers also didn't help.

Basically, I've tried everything I could think and found on internet, but nothing works.

Is it simply dead or this could be some driver issue?

I forgot to mention - it displays error code 43.
