This item works fine in the second install, but had problems in the intended board. Possible driver issues. Good pricing.

This review is from: Syba I/O Crest PCI-Express 4 Ports USB 2.0 Controller Card MCS9990 Chipset (Personal Computers)

I recently bought 2 of these and noticed one of the ports did not recognize any USB device. After ruling out the cables and the device, I took a look at main IC on the board under a scope and could see a few of the pins (4 of them) were not soldered to the board. After a quick re-solder I was able to get it working but most probably don't have a lab and would just return it at that point. Besides that, installation was pretty easy, just snaps in to the PCI slot, no driver or disk needed.

This card is great. I was running out of USB slots and this card solved the problem. I now have plenty of places to plug in all my devices. Works perfectly!
