VirtualBox Harmony remote programming disconnects

Trying to program my Harmony remote from WinXP inside of VirtualBox, I kept getting disconnect errors. Poking around, I found these directions (last four paragraphs of the post) for setting up a filter in the virtual machine configuration so that it automatically connects the USB device (the problem apparently is the remote disconnects when rebooting and without the filter, the virtual machine can't find it then).

Roku N1000 and Linksys EZXS55W equals network woes

Updated 3/13/2010: I've become convince the Linksys in question was just flakey and this was nothing specific to the Roku.

I recently moved my Roku N1000 Netflix streamer from one room to another. On hooking it up I found it performed horribly. Took minutes to start streaming a movie and then it would frequently "hiccup" and have to re-buffer.

Long story short, looks like it just didn't get along with the Linksys EZXS55W 5-port switch I had there. Switch seems to work fine with everything else, so I just swapped it with another switch (different Linksys) and all was good.
