This board probably won't be found on USR's site because of the way these companies merged and split. I had the same issue trying to track down drivers for another USR/3Com combo product many years ago (and never could find anything). Megahertz was purchased (or merged with, depending on whom you ask) by US Robotics in 1995. US Robotics was then acquired by 3Com in 1997. In 2000, NatSteel and Accton formed a joint company, resurrected the US Robotics brand and took over 3Com's modem business. Solectron bought NatSteel in 2001 and in 2004 sold their stake in US Robotics to USR's management. In 2010, HP (sadly) bought what was left of 3Com. Modem-only devices went with the "new" US Robotics company in 2000, but combo NIC devices went with 3Com (now HP). The drivers you need would have been on ftp.3com.com [ftp://ftp.3com.com/pub/nic/XJEM3288/XJEM3288.EXE], which appears to have been shut down after the HP acquisition. This is why none of these searches turn up anything: http://www.google.com/search?q=site%3Ausr.com+XJEM3288 http://www.google.com/search?q=site%3A3com.com+XJEM3288 http://www.google.com/search?q=site%3Ahp.com+XJEM3288 Looks like the driver you need can still be found here though: http://mirrors.muleslow.net/ftp.3com.com/pub/nic/xjem3288/ If someone has any contacts at HP, this might be another thing to point out and see about getting them to fix. The 3Com ftp files are almost certainly still available internally at HP, but they do not appear to be available via any of HP's public ftp servers. I ran into this with some of the Compaq stuff in the past, too.
