How to add USB 3.0 port to your laptop

There are only so many slots available on a laptop and the only one which can to some degree take on the task of providing USB 3 functionality is the ExpressCard slot.

When new technologies surface and we attempt to retrofit that functionality within older form factors there will always be trade offs.

Well for those of you interested, I play around with the odd laptop and have managed to install a Mini PCI Express USB 3.0 card where my WLAN card used to be, in a Compaq CQ60 Laptop. I removed the DVD burner and replaced with a slimline SATA HDD caddy and hacked the side of the slimline case to mount the two USB 3.0 ports.

It works fine for fast USB 3.0 sticks and 2.5" cases provided you use an SSD. Mech drives don't work. I think the problem is supplying 5 volts to the USB 3.0 connectors. At first I thought I'd get the power from the mini SATA port because it supplies 3 V, 5 V and 12 V. But when I checked the voltages with a meter, they are all 0 volts. I think the BIOS only supplies power if it finds a connected device. If I could route 5 V from the motherboard then I'm certain it would work for all USB 3.0 devices.

Here is the card I shoehorned in: http://intrl.startech.com/Cards-Adapters/USB-3.0/Cards/2-Port-Mini-PCI-Express-SuperSpeed-USB-3-Card-Adapter~MPEXUSB3S2

If you have an empty Mini-PCI-E slot, you could try this: http://www.globalamericaninc.com/1507880.html

It's a Mini-PCI-E card with two USB 3.0 ports.
