HOWTO: Find Out if Linux Recognizes my PCI Device.
This is an almost verbatim copy of the post on how to determine whether your GNU/Linux box recognizes your USB device.
First understand that ‘recognize’ is different from ’supports’. Your GNU/Linux box may recognize your PCI device, but that doesn’t mean it has the drivers to run it.
But don’t despair, recognizing a device is the first step to determining whether you can use said device.
Plug the device in and then in a terminal window, type:
lspci
The terminal window should respond with a list of all detected PCI devices. When I do this on my laptop I see:
0000:00:00.0 Host bridge: Silicon Integrated Systems [SiS] 650/M650 Host (rev 80)
0000:00:01.0 PCI bridge: Silicon Integrated Systems [SiS] Virtual PCI-to-PCI bridge (AGP)
0000:00:02.0 ISA bridge: Silicon Integrated Systems [SiS] SiS962 [MuTIOL Media IO] (rev 25)
0000:00:02.1 SMBus: Silicon Integrated Systems [SiS] SiS961/2 SMBus Controller
0000:00:02.5 IDE interface: Silicon Integrated Systems [SiS] 5513 [IDE]
0000:00:02.6 Modem: Silicon Integrated Systems [SiS] AC’97 Modem Controller (rev a0)
0000:00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS] Sound Controller (rev a0)
0000:00:03.0 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 Controller (rev 0f)
0000:00:03.1 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 Controller (rev 0f)
0000:00:03.2 USB Controller: Silicon Integrated Systems [SiS] USB 2.0 Controller
0000:00:04.0 Ethernet controller: Silicon Integrated Systems [SiS] SiS900 PCI Fast Ethernet (rev 91)
0000:00:0a.0 CardBus bridge: Texas Instruments PCI1510 PC card Cardbus Controller
0000:01:00.0 VGA compatible controller: Silicon Integrated Systems [SiS] 65x/M650/740 PCI/AGP VGA Display Adapter
Most of this stuff is built into your computer and there’s not a lot you can do about it (especially since this is the list from my laptop). But look at the second last line. Knowing that it recognizes my PCMCIA Wifi card is useful in case I start having trouble with it.

[...] If your goal is to see if a PCI or USB piece of hardware has been detected, you may be able to use lspci or lsusb while the machine is running. [...]
