Hi, thaoth.
I think that your board cannot communicate with USB device at all. SH7727 has EXCPGCR register. Do you set this register? When I used this CPU before, I did the following setting.
STCBR3 = 0x18; SRSTR = 0x18; wait_10msec();
EXCPGCR = 0x28; wait_10msec();
SRSTR = 0x00; STCBR3 = 0x00;

Hi,
I got USB issue and here is an error message:
ERROR: CTL:TIMEOUT USB device not responding, giving up (status=20) 3 USB Device(s) found scanning bus for storage devices... 0 Storage Device(s) found
For detail, TEngine/SH7727 has one USB host controller, when I plugged USB Flash Memory there were 3 devices. And No unplugged USB device, they said 2 devices.
