Uma maneira fácil de consultar informações sobre um dispositivo é hwinfo(8)
:
# hwinfo --help
Usage: hwinfo [options]
Probe for hardware.
--short just a short listing
--log logfile write info to logfile
--debug level set debuglevel
--version show libhd version
--dump-db n dump hardware data base, 0: external, 1: internal
--hw_item probe for hw_item
hw_item is one of:
all, bios, block, bluetooth, braille, bridge, camera, cdrom, chipcard,
cpu, disk, dsl, dvb, fingerprint, floppy, framebuffer, gfxcard, hub,
ide, isapnp, isdn, joystick, keyboard, memory, modem, monitor, mouse,
netcard, network, partition, pci, pcmcia, pcmcia-ctrl, pppoe, printer,
scanner, scsi, smp, sound, storage-ctrl, sys, tape, tv, usb, usb-ctrl,
vbe, wlan, zip
Pesquisando as saídas do cartão, algo como:
# hwinfo --netcard
