...one of these:

Unfortunately...it doesn't given any power usage data, though a quick check of the user reviews had one saying it runs worm.

I believe some people have done this with mixed results (performance.) The fact is that the Ethernet on the RPI is tied in to USB as well, so the you most like will not “gain” that much. The limiting factor being the USB.

I wouldn't expect to gain anything...at least on a Model B. I'm thinking of the effect on a Model A.

It would permit headless operation with wired network, or a full system with use of a hub on the Model A when those arrive.

I have a USB to Ethernet Adaptor lsusb shows as a Davicom Semiconductor DM960, the datasheet is here:

I have plugged into my Pi with a 5V 1A PSU and appears no adverse effects on keyboard/mouse

I have a similar adapter and I just tried it on one of my Pi's. It seems about about twice as fast as the built in ethernet. It works direct into a USB port on a Rev 2 board. Dmesg reports it as a "ZT6688 USB NIC"
Don't judge Linux by the Pi.......

I have one from Sabrent that did "not" mention Linux, but uses asix module automatically. sudo lsusb -v reports MaxPower 200 mA.

The only caveat is that it is USB 2.0 only, so if you need to use dwc_otg.speed=1 in /boot/cmdline.txt to force USB 1.1 for an errant keyboard that drops/repeats characters, it will not work.

I checked sudo lsusb -v and the Davicom states 2mA
