Hello There,

I am working on AT91SAM9G45 MCU. I want to put the Host USB in the test mode (Test_Packet state).
After going through the data sheet I found that I can use UDPHS Test Register to do that but I am not sure about it.

I am new to USB, so if please anyone can guide me how can I put it in test mode and how can I verify that it is in test mode. Details will be much appreciated.

Thanks,

Hey,

I can't help you here but i'd also like to know if you having problems with high-speed USB by any chance?

I've got a custom G45 board and for some strange reason USB flash devices disconnect instantly when i copy a large file over Ethernet.

We had the same problem with our first revision of the board and so we had the layout/schematics cleared by Atmel engineers before the second spin, but we're still having the same issue. We initially thought it was a crosstalk issue, but appears not to be.

If anyone has had any similar problem with HS USB i'd like to hear.

Hi please_work. I was wondering if you have solved the USB issue. I also am on my second revision of a board thinking that the issue was crosstalk but am still having the same issues. Have you made any progress?

Thanks
OAC
