My M4600 Can not use USB & RS232 Port on Pro2X Docking Station. This is new to me and in 100% mint condition as it had never been used and only turned on about 3 times.
I can use both DVI monitors attached to station, but can not see any of the USB or RS232 ports on my docking station. My old M6600 can see them all just fine.
If the M4600 can not utilize the docking station ports, it is bye bye to the M4600.
