E: (OPTIONAL) Configure USB Driver
Buffer control
The USB Driver Buffer control allows
optimization of the low level USB stream. This
control is found on the Setup/General/Options
form as seen below. Note that PowerSDR
must be in standby in order to change this
control. The default setting has been chosen
to allow successful startup of PowerSDR on
most machines but may not provide optimal
performance on your specific PC. More
aggressive settings reduce latency and
improve keying performance in CW. More
conservative settings will allow lower
performing USB controllers and/or CPUs to
function smoothly. Choose the most
aggressive setting that provides stable
operation without popping or distortion of the
received signal.
