Other Parts Discussed in Thread: TUSB1002A, , TUSB8044AEVM
Often while operating in our instrument, the USB 3 HUB (PN: TUSB8043AIRGCR) drops out of Windows as shown in the attached file.
The USB 2 section of the hub is working fine and does not drop out.
We do have some noise on the VBUS line as shown. However, as I understand it the USB HUB has debouncing logic on the VBUS line. Why does just the USB 3 section of the hub drop out?
Does TI have any recommendations to improve the robustness of the attached design?
