I'm using xubuntu and in my laptop hp 6730b I have a 56k modem but I don't know brand or manufacturer. Looks like it doesn't run in linux but would like to see more info about the device.

Any sugestions?

Already used:

lspci -Vvv | grep -i modem

You could try lspci without the grep just in case it is not recognised as a modem (which is likely). Alternatively:

  1. ScanModem is specifically designed to detect modems under Linux and help you configure them. See here for more information.

  2. hwinfo

    hwinfo is used to probe for the hardware present in the system. It can be used to generate a system overview log which can be later used for support.

    sudo apt-get install hwinfo
  3. lshw and/or lshw-gtk (GUI)

    lshw is a small tool to extract detailed information on the hardware configuration of the machine. It can report exact memory configuration, firmware version, mainboard configura‐ tion, CPU version and speed, cache configuration, bus speed, etc. on DMI-capable x86 or IA-64 systems and on some PowerPC machines (PowerMac G4 is known to work).

    sudo apt-get install lshw lshw-gtk 
  4. The wealth of information available over at linmodems.

  • I would suggest: Look at the device. Open it, look for chip names. Google those.. --- Which of the commands detected the modem? Mar 19, 2013 at 2:28

The HP6730B I've seen had LSI (nee Agere nee Lucent) HDA winmodem inside.

so try lspci | egrep -i '(lsi|agere)'

  • That only gave me the firewire information. lspci | egrep -i '(lsi|agere)' 86:02.0 FireWire (IEEE 1394): LSI Corporation FW322/323 (rev 70) Mar 19, 2013 at 1:10
