Woody,
This appears to be a consolidated opinion among several posters. Still
I can confirm again my experience (as I did in previous posts) as well
as the following excerpt from the manual "KeyspanUSAforXv20.pdf" of the
USA-28X Keyspan adapter. Though Bluetooth transfers require less work
and Ethernet ones are faster, sometime I still use either Newten or NCU
according to the need.

Hope that helps.
