ACK!

I agree with both points too (same here, lots of uplcom, some uftdi, all
working).

For the easy recommendation: try to get the cheapest possible, most likely
it will be a uplcom and work. If possible, arrange for a chance to return,
if you should happen to run into a uark.

For most pieces it will be impossible to know the chipset variant
before unpacking and pluging into your NetBSD machine.

If the connector is not recognized at all, post usbdevs output, maybe it
can be just added to the proper table and trivialy made to work.
