I have also been using the prolific USB-serial for downloading from
volksloggers and connecting old pda's. Had no problems with it.
I wouldn't recommend the Keyspan one though. Very intermittent results.

Subject: Re: [Aus-soaring]USB to serial
A few weeks ago there was some discussion here about USB to serial
convertors and downloading loggers to PC's with USB ports only which
requires the use of USB to serial convertors.
I got a EW Model D in for calibration and I thought I'd check the
downloads on the various serial ports on the lab machine.
It is a 2.4 Ghz Celeron with serial ports on the motherboard. They were a
joke and I switched to a card with 2 serial ports which seems to work OK.
I also have a 4 way USB port expander and have a Belkin USB to serial on
on USB port(Hardly Normal's or other outlets $50 to $80), a "Prolific" USB
to serial on another(Jameco in California US$18) as well as the Com1 and
Com 2 serial ports. There is also a nother USB to serial RS485 convertor
for setting up and calibrating B400's
Results:
Worked perfectly on all 3 USB to RS232 devices.
Possible trap:
After physical connection and pushing the button and holding it down, the
Model D auto selects the port and you get "putting Model D in IO mode" on
screen. After a few seconds the changes to "awaiting connection". Release
the button at this time as otherwise it seems to stay on this message.
