I can't confirm performance with a SDR, but although not cheap by any means the Gefen USB 2.0 extender is rock solid. The max distance I have used these is probably around 150ft with cat6.

...is the only one I've used that worth anything. Another version without the metal case but a plastic one, and almost identical internals is sold by black box. Both are actually/probably made by Icron. These units are the few that actually support USB 2.0 specs and require a dedicated CAT5e between them (yes, it's technically Ethernet, but the spec is a little different and you can't plug a switch in between, they have to be connected direct)

...has also worked pretty good for me, but not all USB2.0 devices seem to work with it. Also you have to manually reconnect it every once in awhile, and there was no way to set it with a static IP on the network (other than DHCP reservation) which I found pretty annoying.
