[Elecraft] Problems with erratic USB/serial connection

[Dennis McAlpine]

I have been using the KUSB USB/serial converter between my K3 and PC for
both DXLab and n1mm.  Lately, I have been having trouble with erratic
frequency readings, mainly on n1mm but sometimes on DXLab.  On n1mm, this
seems to happen mainly when I change bands or after the radio has been in
standby without transmitting for a while.  I also have to run the USB at
19200 rather than 38400.  I updated the Prolific driver with no effect.
Anyone got a solution to this problem?  Barring that, what are people using
for a USB/serial converter now days since I have used the old KUSB for many
years now? Thanks.
