when the USB 2.0 do not recognize your plugin Stick, HDD,SSD, rack anymore--- from 1 restart to another, you can be sure you have rewritten inside the usbstor.sys.
to follow:
1.install again SP1, SP2, SP3
2. install main { laitest } driver from USB STORAGE for your PC -- by goin to PC driver support site , and search for your PC modell
3. after instalation of new drivers Windows/sytem32/ drivers + drivers from PC modell-----use in future this HUB ---
will recognize ALL the plugins - with no conflict after restart { reboot ]
trust me , I tested on HP compaq 6510b with Win XP {32 bits}
all other modeles from Orico - that are mixt USB2.0 with USB3.0 -- have some bugs on XP -- do not registrate corect ALLL THE USB STICKS OR SOME SSD if you are ussing OS WIN XP 32
they want us to force us to switch to WIN 7 - but is not the time-- because we love Win XP still
