Mine is B570 1068 Intel Pentium B950 / 2.1 GHz.

Mfg Date 12/05/2010 , Not USB 3.0
Factory ID : KS
All external USB 2.0 Data lines Dead (disabled USB for all internal devices like camera , fingerprint) . BoardView files calls for USB 3.0 on board which is not the case for mine, .brd on here does not match my model.
I found an USB1 port with around 12 ohm on D- to ground, all other USB D lines ports seems high impedance to ground and Vcc. All USB ports provide +5Vdc supply and are able to charge pluggeed devices.
Not able to find Advanced Bios keys combination if any? And not too much information on how to Disable just one port , in this case the USB1 on failure.
My Bios : Phoenix SecureCore Tiano Setup
Product Name Lenovo B570
Bios Version 44CN43WW
KBC Version 44EC29WW
LENOVO SN WB06302846
UUID Number B32FBA20-9B23-11E1-895E-F60026E159F6
Tried hardwired a 4 pots USB hub on the Wifi WLAN Mini-card and there is not USB activity either on Pin 36 and 38.
Tried to install a MiniPCie card USB 3.0 4 ports on the WLAN and WWAN Mini-Card ports and it was not detected at all.
Laptop is fully operational on Windows 7 and all drivers are installed successfully (including the Intel PCH Cougar Point ) , CD-ROM is the only available external media which is working. The Bios is only able to disable-enable USB Legacy which makes not difference to Not boot from USB in any OS (Linux, MacOS or Windows I have them all on usb).
I am looking for Advanced sequence to Bios or some Bios that have the Advanced features. I will appreciate any help
