Other Parts Discussed in Thread: TUSB4041I
Hi,
We have designed a carrier board for Nvidia AGX Xavier. In that, we used TI TUSB20406I USB 2.0 Hub.
the hub has been enumerated as USB 2.0(480M) in the AGX system. But the problem is that the devices connected to the hub are always enumerated as full-speed devices (12M) instead of USB 2.0(480M).
I have attached schematics of the USB Section. Pls review it and let us know if we did anything wrong.
Note:
initially, we have designed without pullup/pulldown on data lines. After reviewing the datasheet , We have added a 1.5K pullup on the D+ line of the upstream port.
And 15K pulldown in both lines of the downstream port. this is not captured in the attached schematics design.
Thanks in advance!
