Forum Post: RE: [AM335x] USB host mode, DRVVBUS issue

It sure looks like OC...especially since there is significant droop on SYS_5V and you mention that the TPS starts falling first.

What OS is this example running?

What is the capacitance of USB1_VBUS?

If the 830us is correct, it doesn't appear to be AM335x HW behavior.
