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;

Best regards,
Yoshihiro Shimoda
