[Verse 1] Boot up your system, time to explore What hardware lives behind each port and door lspci command will show you the way Every device connected today Graphics cards, network chips in a row Audio controllers, storage to know Vendor ID, device ID side by side Your hardware map, nothing to hide [Chorus] List PCI, List USB too Kernel docs will guide you through Match the driver to the chip Hardware detection, what a trip lspci, lsusb, documentation Perfect driver combination Find the code that makes it go That's how system engineers know [Verse 2] USB devices need their turn lsusb shows what we can learn Bus and device numbers clear Every gadget plugged in here Mice and keyboards, cameras bright Storage drives and wireless might Class and subclass tell the tale Of which driver will not fail [Chorus] List PCI, List USB too Kernel docs will guide you through Match the driver to the chip Hardware detection, what a trip lspci, lsusb, documentation Perfect driver combination Find the code that makes it go That's how system engineers know [Bridge] When the hardware speaks unclear Kernel documentation's here Module loading, one by one Match the driver, get it done Check the logs for what went wrong Debug with your hardware song [Verse 3] Dig through docs in kernel source Find the driver, stay on course Compatibility tables show Which hardware versions go Load the module, test the link Everything connected in sync Full stack knowledge, top to ground Hardware drivers safe and sound [Chorus] List PCI, List USB too Kernel docs will guide you through Match the driver to the chip Hardware detection, what a trip lspci, lsusb, documentation Perfect driver combination Find the code that makes it go That's how system engineers know [Outro] From silicon to software stack Hardware detection, that's the track Every chip needs its perfect mate Driver selection, don't be late
