I have used the two-port version of this with Linux and it "just worked,"
wondering if anyone has used this (or something similar) successfully with OpenBSD? I am
looking to manage a few switches via their console/RS232 interfaces.

Haven't used /that/ one, but have used a couple, and yes, "Just Worked"
for me as well. I have USB to eight port serial in remote
production. The one I have have been around for many years, so unlikely
you would be able to get something that is completely identical.
Here's how one of them shows up in dmesg:

One cool thing: the device enumeration is rock solid -- once you
know what device is on what port, it seems to stay that way.
One down side: once in a while, the thing locks up, where OpenBSD
can't open the serial port (iirc, all of them wedge at the same time,
but I'm not going to swear to that). I'm not sure who's at fault
(OpenBSD or the device), but a reboot does fix it, Which is good,
since I and the systems I manage with it are separated by an
international border and 400km :)
So ... I'd not suggest attaching it to an "important" system, but
rather dedicate an easily rebooted terminal server machine.
