TUSB1310A use for 2.0 OTG device mode

Other Parts Discussed in Thread: TUSB1310A

Hello all,

I have a FPGA board with TUSB1310a on it.

And I have alreay test it with normal USB2.0 device IP with this FPGA board, and it works fine.

Now I am trying to use this FPGA board to test my USB 2.0 OTG IP, and I fix my USB OTG to "device mode".

but it looks like the reset handshake did not pass, my PC can not detect my OTG device, and my OTG IP shows that the reset handshake did not been detect.

But the TUSB1310a output a ulpi clock with 60MHz, and I have found out that the ulpi data are transfer on the ulpi bus.

So I am wondering can TUSB1310a can support USB OTG device mode?

And I have a question for it, will TUSB1310a report the ID value in it "RX CMD byte"? and what value is it?

Thank you for your reading

Regards
