Comment 2 for bug 519905

Only one model of hub has been tried (3Com OfficeConnect Dual Speed Hub 8 -- it's an 8-port 10/100Mbit hub), but we have tried with 3 of these and they all exhibit the same problem.

Boards running karmic and jaunty (and very early builds of lucid) communicate fine though these hubs, as does everything else we have connected to them. However, any imx51 board running a more recent lucid (Babbage 2.0 or 3) has the problem.

A direct cable connection to another host, or a connection to a switch does not have the problem.
