I went here and looked at a very long list of manfid descriptions, and found none referring to storage devices or drives.http://tuxmobil.org/pcmcia_linux_manfid.html
The manfid for my C3100 microdrive is shown below (from the console)
product info: "HITACHI", "microdrive"
manfid: 0x0319, 0x0000
function: 4 (fixed disk)
I also found a site that lists manfid numbers for ethernet cards only.http://tldp.org/HOWTO/Ethernet-HOWTO-4.html
I'm hoping there must be a site with most all available manfid s
The first site above shows many of these manfid, but they are for network, bluetooth, and other purpose cards, (excluding drives and storage cards)
