Claim 9:
10. The method of claim 9, wherein calibrating Rrx_h or Rrx_d during the third calibration process comprises:
when Rtx_h and Rrx_d are calibrated during the first and second calibration processes,
adjusting a resistance of the Rrx_h over a small range having multiple resistance values including the preset value for Rrx_h;
measuring, at the multiple resistance values, a peak amplitude of a signal received at the device receiver that is transmitted by the host transmitter; and
determining a calibrated Rrx_h as the resistance value among the multiple resistance values that yields a maximum peak amplitude of the signal received at the device receiver,

when Rtx_d and Rrx_h are calibrated during the first and second calibration processes,
adjusting a resistance of the Rrx_d over a small range having multiple fine resistance values including the preset value for Rrx_d;
measuring, at the multiple resistance values, a peak amplitude of a signal received at the host receiver that is transmitted by the device transmitter; and
determining a calibrated Rrx_d as the resistance value among the multiple resistance values that yields a maximum peak amplitude of the signal received at the host receiver.
