Q: MacPro 3.1 USB and Bluetooth problem

i have problem on USB ports in my MacPro 3.1 in MacOS X 10.11.x

I update my Mac from 10.6.8 to 10.11.6. The problem is that when connect the USB Flash Drive (extFAT) system not see the disk. Or maybe after disconnecting and reconnecting the keyboard/mouse system not see again device.
Apple menu > About This Mac > More Info > System Report > USB | too not see USB device. And Bluetooth also doest exist.  As if the system USB ports are completely cut off: - / 10.6.8 for any problem.

MacPro 3.1 2.8 (8 core), 14 GB RAM, 8800 GT 512th (original 980W power supply) - CZ language mutation
3x 3,5" HDD (500,500,320). Without PCIe cards (USB, LAN, SAS, SATA, etc.)
Boot ROM: MP31.006C.B05
SMC: 1.25f4

Reinstall MacOS, reset NVRAM or SMC does not work :-/

I test and download "USBEHCIPCI.kext.zip" from http://www.insanelymac.com/forum/topic/306777-guide-usb-fix-el-capitan-1011/    and with the "patch" working my rear usb (max. 1MB/s) but not front USB ports.
