Of course, I have a cool card from a desktop I'm retiring, that I'd like to be able to use from the laptop I've replaced it with.

Laptop has no docking station. Best I can replace the card for is a LOT of money, it works hand in hand with an app I'd love to retain.

I want a device to give me access to PCI via PCMCIA or usb2.0 (laptop is a few years old and doesn't have the newer slot). Separate power is OK.

I would think it would be easy to find if such a device existed. All my searches turn up a million USB port cards that plug into a PCI slot - the opposite of what I want!

Does such a converter exist? I'm aware of difficulties to this, but am not interested in the why, only if you can drop a name, or say for sure it doesn't exist. thanks!

USB 2.0 is less than half as fast as PCI - on paper. Transfer rates will be less than that. What is this "cool card?" Isnt there a USB device that does the same thing? – Keltari Sep 2 '11 at 2:40

@Keltari - It's something that doesn't require a very high bandwidth ;-) – FastAl Sep 2 '11 at 3:21

I'm still not sure what this cool card you speak of is. – Sam Sep 2 '11 at 7:00
    
@Keltari What about USB3? – Milind R Nov 20 '14 at 15:33

There's Magma 1-Slot Cardbus to Half-Length PCI Expansion Unit and Magma 1-Slot Cardbus to Full-Length PCI Expansion Unit that will connect cardbus to a PCI housing, but at about $1000 it is NOT cheap. You could get a new PC with a PCI slot for less. Magma also offers a fiber to PCI expansion chassis, but I doubt that would be much cheaper and you'd have the added cost of a PCMCIA Fiber nic

Yikes! I figured as much. I could replace my current solution for that kind of jack. I had just hoped I could pick up a usb2pci like a usb2ide ;0 wishfully perhaps. – FastAl Sep 2 '11 at 3:33

What OP wants is not a common configuration, so I would not expect mass market prices. – Sun Sep 16 '14 at 2:42

Haven't tried it myself, but perhaps you could use a pci to express card adapter, and then an express card to usb adapter. The below total approx $127 + shipping and support 2 full size card, compared to buying Magma's adapter which is $1159 + shipping, and only supports 1 card. Unfortunately the PCI adapter is not from a brand, it's just a generic adapter found on Ebay.

Sorry, but no. He needs to go in the other direction. – Jamie Hanrahan Sep 16 '14 at 1:43
    
@JamieHanrahan: Take a closer look at the products suggested. They are in the atypical direction. – Ben Voigt May 29 at 16:43
    
@BenVoigt That EC-to-USB thing doesn't give you a real ExpressCard slot. The "ExpressCard slot" made by this "ExpressCard to USB" thing has only the USB pins at the bottom. So it won't support a real ExpressCard. You see, a lot of "ExpressCard" cards are really USB devices with a funny-looking connector. The EC slot includes pins that provide a USB port to such cards. – Jamie Hanrahan May 29 at 19:27
    
btw, every "ExpressCard" flash card reader I've tried has worked this way (evidence: "show devices by connection" in device manager clearly shows the reader connected via USB). It's far cheaper and easier to build such things than to build real ExpressCards. For the user, it saves using up a regular USB port and it isn't an extra thing hanging off your laptop. But it has no speed advantage vs a USB card reader, which is what I was hoping for. Feh. – Jamie Hanrahan May 29 at 19:30
    
@Jamie: Yes, you're right about that... the ExpressCard slot has both PCI(e) and USB interfaces, and this adapter would only support the latter. These days we're playing that same game again with M.2 SSD slots, some of which have SATA only, some have both SATA and PCIe (and I suppose it would be possible to have PCIe only but I don't think that's as common). And of course the generation in-between, miniPCI slots, also had both PCI and USB busses. – Ben Voigt May 29 at 20:08
