[Elecraft] KUSB Universal Serial Bus Adapter?

[Dave G4AON]

You pay your money and you take your chances! I don't need one for my K3 
as I use the shack computer with 8 real serial ports. For portable use 
(with other gear), I have a couple of USB to serial adapters on a 
Toshiba laptop that work well, they were about the equivalent of $30 US. 
I bought two of the same brand as it drives me mad trying to cope with 
Windoze trying to install drivers all the time when you plug an adapter 
into a different USB port to the one it was set-up to use initially.

The "other gear" mentioned above is a Nokia 3210i phone used as a GPRS 
modem and a TS-480, for our UK readers the USB to serial adapters were 
from Maplin.
