[Elecraft] KUSB and Logger32

[mm0gpz]

I purchased a KUSB cable and downloaded the latest driver (v2.0.4.102) from
the Prolific website, as directed on the Electraft website, for my K3. 
Although the Elecraft Utility program worked perfectly, and I found that
full rig-control worked in Logger32 but with CPU running at 100% constantly.
Obviously this was a problem as the pc slowed to a crawl. PC is 2.2 Ghz with
1.5Gb ram. Running other logging software (Wintest, HRD) was fine with no
addition CPU loading. Only Logger32 displayed this 100% CPU payload. To
further test, I installed the prolific usb-serial driver onto 2 other XP
laptops. One was brand new out the box and all 3 had different Anti Virus
packages. The exact same poor behaviour was found on both as on the original
XP Home desktop.
The resolution was to uninstall the USB-Serial driver and install an older
Prolific driver (v2.0.2.8) which resolved the issue. Link below.

I'm not sure how many are using Logger32 but this driver may be causing
issues for others?

Thought I would share this in case it helps someone.
