It isn't the USB as much as the driver... I have been using a microHAM USB
interface with good luck this weekend. See
_http://www.microham.com/USB%20interfaces.html_
(http://www.microham.com/USB%20interfaces.html) . When it
first came out, the USB driver had problems (the same as you noted) the
computer
generated cw was useless... They (microHAM) created a new driver and this
weekend I have had a chance to use it in the CQ WW WPX CW contest. I have
had few if any request for repeat. It works great and sounds great (at
28wpm).
Now if only writelog would do a better job of decoding the received cw...
and yes, I have heard some very poor generated cw.
btw, I am using only the cw functions (function keys, keyboard, and decode)
within writelog. microHAM provides only the virtual COM port to the key
input on the rig. I also use the serial link to the rig (read frequency).

Your problem most likely stems from trying to use CW with a USB-to-
Serial adapter. I've had no luck with different computers and
different adapters in getting really "clean" CW. I've also been told
that driving an external keying device through the USB port would be
unlikely to solve the timing problems that are the issue.
Does that laptop have a serial port? If so, you can solve your
problem by using that for the CW interface. If it doesn't, I would
look into a different computer for your station operation.
That's my experience. As always, YMMV.
