Issue

  • I am trying to locate the device ID on my network cards but I cannot  find that specific information, I need that information to upgrade my  drivers.
  • How to findout the Device ID of Network Card ?

Resolution

The command lspci will show you the Device ID of your Network Card or any other pci device . Depending on your system you may be able to run this command without having to be root first.
Try  -nvv options with the lspci commad to get the Device ID of network card.

lspci -nvv

This options  will display lspci output in verbose mode with the numbers without performing a lookup in the device id list.

For example:

lspci shows the following nic card on my system:

09:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5752 Gigabit Ethernet PCI Express (rev 02)

lspci -nvv shows

                           +------- vendor id (Broadcom)
                           |       +--- device id
                          V      V
