lspci | grep -i [device]

The command lspci | grep -i [device] is used in Linux to filter and display specific PCI (Peripheral Component Interconnect) hardware components attached to your system's motherboard. The lspci utility lists all PCI devices. We then pipe(|) the list to grep and parse it looking for the given string [device]. When using a simple, single word expression, wrapping it in quotes isn't required. More complex expressions would be though. We always wrap them in quotes, for consistency. So, I guess, the quotes are up to you. Here are a few commonly useful variations:

If your search does not provide enough details, you can expand the results with these flags:

Advanced Hardware Inspection Flags

• lspci -v (Verbose): Displays detailed driver configuration and memory allocation information.
• lspci -nn (Show IDs): Displays both the textual hardware name and its corresponding vendor/device ID numbers.
• lspci -vnn | grep -i -A5 "vga" (combination search): We tell it that we want; verbose output, to show IDs, and to show the next 5 lines (-A5) as well as/ after the one our search matched.
• sudo lspci -v (SU Verbose): Sudo (SuperUserDo) runs the command as the administrator. Displays detailed driver configuration and memory allocation information including hardware regardless of owner.

For more info, a little tldr;, visit our lspci Manpage. lspci is part of the pciutils package. You can use lsusb to get similar information on USB devices.
