I have a Trimble Acutime Gold GPS[1] and I got some problems installing that
device in both FreeBSD and Linux. That GPS has an USB Interface with FTDI
support.
FreeBSD configuration:
1) kldload uftdi
2) dmesg:
ucom0: FTDI Dual RS232, class 0/0, rev 2.00/5.00, addr 2 on uhub3
ucom1: FTDI Dual

First, USB serial devices generally have a *lot* of jitter on them.
Second, have you seen:

Hi Pedro,
You will be in good shape with USB serial if you can find some other way
to get a PPS signal into your box.

Yes, I have seen the support page about Trimble/Palisade but I could
not find any thing to justify the reported problems.
