Active POE is mostly active from the power supply side. It first checks for specific resistance and then ramps up the current.

yes, that will work. Either USB<>RS232<null-modem-cable>RS232<>USB or get cheap TTL UART modules and connect them together (they are like $1, connect RX to TX on the other one and vice versa).

r00t

You can use any common USB to TTL (or RS232) serial adapter and then spawn console on this port to get console.
Almost all chipsets work (FTDI,Prolific,SiLabs) but from my experience Prolific chips tends to freeze, FTDI seems to be much more reliable.
