Instead of cascading a 34 switch, get a 33 switch. 34 is DP, the 33 Switch is DPP and doesn't need the power inserterGood point Bobby.. I've had 2 of my 211's burn up the power supply after adding usb powered EHD to them..I thought about that possibly burning up the 222k..I think I'll get the DPP44 with the inserter and try cascading the DP34 off of it and the 2 cable's to the 222k..
