I have a 3com 3c460B USB ethernet adapter that I'd like to trade for one of the following: 3com 3C460A 3com 3C19250 3com 3C83510P-01 The above 3 are 10Mbps only. The one I have is an autosensing 10/100. I mistakenly bought the 3c460B instead of the "A", and it won't work for what I need it for. Mine is brand new and works great. Willing to trade even up, and I'll buy a beer or two at the next beer meeting for whoever has a trade. :) I actually need 3 of the above adapters, so if someone would rather sell than trade, I'm all up for it. Thanks. Jay
