USB PC Card not recognized

I just bought a USB 2.0 Card Bus Adapter, a PCI Card with usb hubs on the end, because my built in USB Ports no longer work. But when I plug in the PCI card nothing happens. Are these devices supposed to auto mount? How can I go about trobleshooting/fixing this problem?

It depends on your distro and kernel. At a minimum it should show up in lspci if it's a known device. And you'll likely need kernel modules to use it (lsmod). usbcore, ohci-hcd OR uhci-hcd and ehci-hcd for usb 2.0. I don't know if there's anything other than that needed for the pci as opposed to integrated.

$ lspci | grep -i "usb"
(should show that it's there)

$ lspci -v | more
(should show some info on whether it's OHCI or UHCI)

$ lsmod | more
(should list usb supporting modules, IF they were compiled as modules)
(otherwise there should be something in /dev/ or /proc/ identifying them)

$ lsusb
(works a lot like lspci, but shows what's connected to usb)

$ usbview
(a little more humanized / gui-ish)

I tried these commands but I am not sure what I am looking at or for. I am very new to linux and not yet used to doing things like this but I am trying to learn. I installed usbview and when I started it i got a message saying

Can not open the file /proc/bus/usb/devices
Verify that you have USB compiled into your kernel, have the USB core modules loaded, and have the usbdevfs filesystem mounted.

I am not sure what all this means. My USB ports have gone out and I am trying to use this PC Card as a USB substitute. I got one that has 2 USB ports on the end but I can't seem to find tutorials on how to make them work with Ubuntu. Any ideas?
