I recommend you to load your BIOS defaults and update the BIOS via F7 method. If the problem continues please contact your local warranty support to get assistance on replacing your motherboard.
Thanks for your suggestion! it worked-kinda.
After re-flashing BIOS 61 with the default CMOS setting, both ports in the dual port internal USB3.0 connector work with the Front Panel 3-1/2" Bay dual USB3.0 module that is supplied with the MoBo.
However, the single A-style USB thumb drive port on the Silverstone FP37 3-1/2" Front Bay module has yet to work with a USB drive. The memory card reader ports work but the USB thumb drive port does not.
The only change with the FB37 is the drive light on the USB3.0 thumb drive does flash once but a drive folder does not open in explorer.
FB37 is a USB3.0 hub on one of the internal connector ports for the 5 front panel card reader slots (5 drive Icons show in Explorer - 1 for each of the 5 card reader slots), however the other internal port should be connected directly to the A style USB3.0 connector on the front panel as a simple pass-through cable according to Silverstone support.
If the FB37 and the Intel Front Panel 3-1/2" Bay dual USB3.0 module are installed together neither of the A-style ports on the Intel module work but the FB37 card reader drives are still showing in Explorer. Disconnecting the FB37 will allow the Intel module to work after the USB Surge Errors (known issue) are cleared.
From that, I must assume the FB37 HUB/card reader firmware is incompatable with the Intel USB3.0 driver and prevents the other ports on the internal USB3.0 headers from functioning correctly.
All 4 of the rear panel UPS3.0 ports work with the FB37 installed.
Any other selection?
