Reason for a detection status failure:
none (1)
dcp (2) - Positive DC supply connected at the port
hicap (3) - High Capacitance at the port
rlow (4) - Low Resistance at the port
detok (5) - detection ok
rhigh (6) - High resistance at the port
open (7) - open circuit
dcn (8) - Low impedence to Vee at the port
tstart (9) - Startup failure at the port
icv (10) - Current limit disconnect timeout at the port
tcut (11) - Overcurrent and current limit violation at the port
dis (12) - DC load disconnect
sup (13) - Supply fault at the PSE device
pdeny (14) - Power Denied
