lspci -k | grep -A3 -iE 'ethernet|raid|sata|sas|nvme|non-volatile'

Shows only network and storage controllers from the PCI device list, each with the following Kernel driver in use and Kernel modules lines. This reveals, for example, whether a hardware RAID controller is installed and which tool you need to monitor it. lspci without a filter lists all devices, lsusb the USB devices.

Note: If the command is missing: apt install pciutils (for lsusb the usbutils package).
