: IFC-PCIE2U3 USB 3.0 card not recognized on my ESC P4M900T-M motherboard in the PCI Express slot
: fredq March 06, 2011, 07:11:27 PM

I purchased a Buffalo IFC-PCIE2U3 USB 3.0 card.  It is properly inserted into my ESC P4M900T-M REV 1.0 motherboard.  I connected the power cable to the new card, it boots up fine, but Device Manager does not recognize it.

It is inserted into the small/short PCI Express slot.

I have Windows XP.

Do I need to change any settings in my CMOS?

Upgrade my BIOS?

Any help would be appreciated.

I would upgrade my bios. If it is not seen then I would try another PC. If that does not work then I would replace it.

I had a similar issue with the IFC-PCIE2U3 USB 3.0 card when I installed it.  It appears that card will not work under Windows XP (32) if you have 4GB of RAM installed.  I removed 1 GB of RAM and it works okay.  This issue is mentioned in the documentation on the CD some place, but is not available for prospective purchasers.

Do you have XP 32bit or 64bit?

If 32bit, how many GBs of RAM is installed?

I read this on page one of the manual:

    "Not all peripheral devices support Windows Server operating
    systems. Buffalo supports use in Server environments when using
    supported Buffalo products. If 4 GB of memory or more are
    installed on 32-bit versions of Windows Server operating systems,
    the card may not function properly."

And I figured that was the reason my WinXP(32) OS was not recognizing
the newly installed USB-3 card.

Subsequently, I removed one GB of RAM, and cleaned the PCIx slot gold
fingers with a camel's hair brush and compressed air, then rebooted,
and it functioned nominally. 

After receiving a tech-support  response, implicit in which was the notion that
the amount of RAM shouldn't be a factor, I reinstalled the 1GB DDR3
RAM module, bringing the total back to 4GB, and booted the system. 

All seems fully functional now.  I am able to access the drives
attached to the IFC-PCIE2U3, and writing 2.4GB takes about 30 seconds!

I guess the true cause of my issue was the dirt that may have
accumulated on the PCI express connector gold fingers over the three
years it was open to dust in the environment.  ?
