External usb drives and Win 7 discovery/connection issues

[trinaz]

I have three external usb drives - 2 are actual drives and the third is stick. I also have 4 usb 2 ports on my MB - and an additional 4 port USB 3 add-on card. I find that if the 3 externals are plugged into the USB2 machine ports...they show up in bios boot screens...but...if I use them in the USB3 ports on the card...they may or may not be discovered in the bios startup read out ?

From a difference of 1) performance...and 2) Windows ability to find them all the time at startup...is there a way to use them with the add-on usb card (USB 3) rather than the MB's iUSB2 internal ports ?

Thanks...TiminAz

Tim mate had a similar problem not that long ago and it turned out to b a faulty card but on the replacement card I still could not get any connection so I took the card out of the small slot that I had it in and put it in one of the spare PCI slots and it worked.

The other thing is I suppose any software required was installed if any and that the power was hooked up ok? Plus any drivers required for the board slots?
