In general go to
http://www.usbgear.com
and click on USB serial. They've got a lot of form factors (cable
end, octopus, desktop boxes, surface mount boxes, rack mount boxes,
and I believe some DIN rail mount models), and they generally list the
chipset used.
The particular one I'm using is

I've had it in limited use for about a year, but I've only completely
populated it and gone into full production mode in the past few
months, connected to a bunch of APC UPS units, some switch consoles,
and some SPARC server console ports. No problems so far.
I've also got one of these:

It's probably 10 years old at this point, still going strong. The
ports seem to have a unique ID, although I only have one of these
boxes so I can't really say for sure. The nice thing about this one
is that it works with Solaris.
Those are all server room applications interfacing to UPS units,
serial consoles, etc. On my temporary balloon chase mobile rig, I use
one of these:

It's from FTDI, works great. This particular chip has 4 RS232 ports on
a single IC. (My 16 port rack mount is 4 of these things in one box.)
I just wish they'd provide an enclosure with it.
