That slightly reminds, back earlier I had the board in a different case where 
the fron port showed some other (better but also not  useful) weirdness, 
propably something to do with the pinout chart. I don't remember exactly.

Also, it appears that you are using 1MB capable usb flash on front, 40MB/s at 
the rear port? That brings me to the idea, do you have legacy usb enabled in 
bios or not? Cause, when I disable, I get other head power values than with 
legacy enabled.

Legacy disabled:
Timecounters tick every 1.000 msec
usbus0: 12Mbps Full Speed USB v1.0
(hw power) control head <= 0x3ed8000
(hw power) control head => 0x3ed8000
usbus1: 12Mbps Full Speed USB v1.0
(hw power) control head <= 0x3f28000
(hw power) control head => 0x3f28000
usbus2: 12Mbps Full Speed USB v1.0
(hw power) control head <= 0x3f84000
(hw power) control head => 0x3f84000
usbus3: 12Mbps Full Speed USB v1.0
(hw power) control head <= 0x3fc3000
(hw power) control head => 0x3fc3000
usbus4: 12Mbps Full Speed USB v1.0
(hw power) control head <= 0x2e02000
(hw power) control head => 0x2e02000

Legacy enabled was:
