I have one with a Prolific PL-2303 chipset:

ucom0: Prolific Technology Inc. USB-Serial Controller, rev 1.10/3.00, addr 5

It works great for standard serial communication, but not for what I
want to use it for : read 'ticks' from my geiger counter.

A 'normal' 16550A serial port chip does that just fine.
