so i got the blackwidow v4 pro and kraken v4 pro. noticed headset not showing in synapse v3 and updated to v4. after uninstalling v3 and installing v4 with the installer it had me restart my pc. after getting back into windows 10 none of my usb devices are working, including non razer devices. i had to track down and order a ps/2 mouse to do anything on my pc to try to fix this.
uninstalling and reinstalling synapse did nothing. uninstalling the now broken code 19 usb devices and allowing them to reinstall didn’t help as well. tried running system file checker with no luck either.
any help to fix this would be greatly appreciated.
