Hello. I tried your solution first.
Did everything step-by-step because I wanted to use my DS3 in bluetooth mode.
When I entered Shibari I tried to connect my DS3 through USB, tried to add it as a bluetooth device on Windows (10) but it wasn't getting recognized. So after reading again your steps it was told that Fireshock could't exist with PSNow Drivers.
I suggest you to warn about this before someone tries to follow the first step...
So I uninstalled everything: Vigem, Fireshock, BthPS3... now even PSNow and it's drivers. Rebooted my PC.
I tried again to install for the second time the BthPS3... and again it didn't work.
So I gave up and uninstalled everything. I even tried to follow the tutorial that "Nukes Vigem", but the Powershell commands partially worked. And I deleted the .SYS. Rebooted again.
Then I tried to install again PSNow and it's drivers. Then I rebooted and when testing my controller over Big Picture on Steam, it wasn't getting recognized at all! And at the Device Manager it told me the "Wireless blablabla PS3" was there through USB obviously.
So I uninstalled everything again. And I even uninstalled from the Device Manager the "Wireless... PS3"...
I rebooted my pc again and when I plugged my DS3 Windows told me it was preparing things up...
So magicaly (my Steam was opened) and for my surprise a toast notification told me it was recognized and loaded my profile, for a second.
When I tried to open the BIG PICTURE my control wasn't working at all.. I checked the configuration if "PS3 mode" was checked and it was. And below that this time my DS3 was recognized but as I told, it is not working.
So I had hope and installed PSNow one more time and it installed it's drivers.
"Wireless blablabla PS3" appeared again in Device Manager, I loaded Steam, entered BIG PICTURE...
Again my controller didn't respond or work at all... and it wasn't recognized there.
So I'm helpless. I searched all over internet and I do not know how to make things work again.
Please, help. I do not want to reinstall my Windows and I don't have time (I work from this same pc).
I'm very tired. =/
