[Elecraft] KUSB Update

[Rajiv Dewan, N2RD]

I was having difficulty updating my K3 with the latest version of the 
DSP code.  On Greg's recommendation I updated the KUSB driver and that 
solved my problem.

I could not find the link to KUSB driver on the Elecraft site, but found 
them on www.prolific.com.tw.  The device is PL-2303.  I updated the 
driver from 2.0.0.18 to 2.0.2.8 (on WinXP SP2) and it solved the DSP 
update problem via KUSB.
