thanks for the reply... unable to check any thing as error reports can't find usb device. However the usb3.0 drives show up and just continue to load and unload ( in a loop) . Also in the devices a find a "SATA BRIDGE" APPEARING DURING THE OPERATION. When I disconnect, the BRIDGE device closes and disappears.
During error test I receive the report " MASS STORAGE DEVICE HAS A DRIVER PROBLEM "
Running A hp h 1212 ONE YEAR OLD. This unit has a Texas inst. usb 3.0 ext. host controller. I have updated driver no change.
USB 2.0 running very well so I'll just leave it be for now , before I really screw something up !! THANKS AGAIN
