Koutech 4-Port SuperSpeed USB 3.0 PCI Express (x1) (3x Ext + 1x Int) with 4-pin Molex Power Connector Model IO-PEU434

Pros: None

Cons: Simply NOT buy! One star because its a required field.

I have a Win 7 SP1 install on an Intel-based PC. The card was received WITHOUT the normal NewEgg paperwork - bad omen. I installed the card, including attaching a spare 4-pin Molex.

When I went to install the driver the install errored out, "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)".

I went to the driver site noted in the "User's Manual" that came with the card and downloaded and appeared to install the driver provided, dated 6/28/2013 (DL-0313102). Restarted and went into Device Manager...yellow triangle and the same error message.. Uninstalled and tried again - same result.

I then went to the Koutech site downloaded and appeared to install the only driver they had (dated 3/2012). Same problem.

I will now "gently" remove the card from the system and return it to NewEgg for refund, left to run my nice new external USB 3.0 HDD off a USB 2.0 port.

Seriously urinated!

Other Thoughts: Now who do I trust to have a card - and drivers - that work?
