Make sure that you tell nqc (or MacNQC) that you are using a Scout. You
can do this by adding -Tscout to the command line (NQC) or selecting the
appropriate target in the preferences dialog for MacNQC.
The USB tower and Scout seem to be very sensitive to distance when
downloading a program. I found that about 18" works well. Closer or
farther than that tends to get a lot of errors. I'm not sure why this
happens, although I'd speculate that the USB tower is transmitting much
brighter than the serial one, and that the Scout transmits fairly
weakly. This mismatch means that too close and the USB tower overpowers
the Scout's receive cicruitry, but too far away and the tower can't hear
the Scout. When I get a chance I'll look to see if there's a way to
lower the transmit power of the USB tower (which would then perhaps make
close range communication more reliable).

I was looking through the NQC source code for using the USB tower and noticed that the Mac OS X version of NQC supports an options -Susb:short which will use the USB tower in short (...)
