Recommend a USB to RS-232 serial port adapter?

[Mawrob]

Can anyone recommend a current USB to RS-232 serial port adapter that works with the SheevaPlug Ubuntu distribution that I can order online?

Thanks for your help.

I've been told this one works, although I do not own one nor have I tried it.  (If anyone can confirm, I'd appreciate it, because with luck I'll also be needing to hang a couple serial ports off my Sheevaplug eventually.)

I own this one:

And it works well in Windows, Mac and Linux. Haven't tried it yet on the plug, but I believe the chipset is supported.
