BIOS update cause USB issues!

Elitebook 8460p
Microsoft Windows 10 (64-bit)


I got a BIG and very irritating problem with my Elitebook 8460p wich I use for my auto workshop.
The Laptop is also encrypted wich makes it more irritating to restart the laptop everytime I need to plug in a USB device specially in front of customer or in the rush. 

This problem I believe (not sure) started after I installed the latest bios 

HP Notebook System BIOS Update F.67 Rev.A 12.4 MB 28 feb 2018 - for this laptop. Before it was F50 from 2014 I believe and everything worked fine.

I've tried a ton of things but still it doesnt want to be working.
I tried going to device manager to unistall, unplugg wait 1 minute and insert usb. Unchecked a thing in battery settings, went to check and correct things in regedit, even checked services.msc without any success. This thing is making me crazy! 

Everytime I connect a USB device, no matter what it is, same thing with the memory card reader slot wich I tested yesterday and was still the same I get explemation mark on the device in device manager. I manually install Disk drive, restart laptop and then it works. If i unplug it and re-plug the same usb again, I doesnt want to work again. There is something really wrong here, Its very time consuming and irritating. Please is there anybody that could help me with this issue? Its a pain in the a** really... Yesterday I located the BIOS IC Chip and even ordered FIVE of them just in case this happens to my collegues and to download F50 bios version and have it written to the chip and solder it to my laptop, what a project but anyway.. This is my last step but before the IC chip comes and I start to unsolder it... Has this happen to anyone else before? 

Please notice, dont give me an answer like re-install windows 10, because that I will not do. 
I need to solve this problem because soon this laptop will be on the wall thanks to that useless BIOS update made.


Thank you. 

Best regards
