No.  If you plan to connect the computer to the K3S using the internal
USB port, you need to use the optional CBL3Y cable from Elecraft to
connect the P3 as documented on page 18 of the K3S Owner's Manual.

The alternative is to use the standard E98097 cable to connect P3 to
the K3S and connect the computer to the P3 PC jack using the K3USB
or a standard serial port a shown on page 19 of the K3S Owner's Manual.
