Just got a new PCIe card, how do I tell if it is working?

Hello all,

I just built my own desktop, with the specific purpose of using it to run audio software. Everything is working like a dream, all of my hardware is working, CPU and RAM are great etc.

Before, I'd been using an express card on my laptop to read my firewire device. It's a high-end express card, so I figured I would like to use it on my desktop. I bought a PCIe card capable of reading express cards and installed it. It is, however, not reading my interface. Or my software isn't reading my interface etc. Before I go into troubleshooting for my interface, I would like to make sure that my PCIe device is not the issue. Where can I tell if my mobo is reading my PCIe device? I'm having trouble figuring out what it would be in Device Manager (running windows 7).

Thanks all

Make and model?

Also, those Express Cards such as you see at often require their own drivers so no, it's rarely automatic. Always check the maker of the card reader and the card to find drivers.

The instruction manual said that drivers are not required

Keep in mind that

This still means your machine's drivers may have to be proper. That is, it's never a sure thing that the chipset driver is native to Windows or that Microsoft supplied the right one. And again, you have the cards to check as well.

PS. Think of this card as a cable.

No drivers are needed for cables but what you plug in, often requires a driver. Or the OS requires a driver for the motherboard.

What kind of drivers?

I mean, I've installed all my mobo drivers, chipset drivers etc. And I have other PCI devices (video card) working just fine on this machine. So what else could it be?

It could be defective, incompatible.

Best to try it back in the old or other machine to sniff out where the issue is.

Yes But

Where would it show up in device manager?

Cables don't show up there.

Since Express cards are just a re-work or re-wiring of the PCIe bus, it is very possible there would be no entry in the device manager until there is a card there. But to solve this and nail does what it is, another PC for testing.

I didn't mention this earlier so let's get these out of the way.

1. The card is in a dead slot or not fully seated. Move it and make sure it's fully seated.
2. A few of the older PC-Card adapters I used had a power supply connection. I didn't find a full manual on this card so I leave this research to you.

It looks like this is some machine someone built. If so, take to the builder about trying this card in one of their other PCs.
