Hi Sir,
TUSB9261 and Vl813 are shared in our project WIDI HOST,
Some products found that the device can not enter the USB 3.0 mode, but only USB 2.0.
Because our design is TUSB9261 to enter the USB3.0 mode when the power on, but it's fail now.
However, after the vl813 is powered on, the device can access USB 3.0 with a delay of about 0.5s.
Without this delay, some devices can only access USB 2.0.
The proportion of this phenomenon is about 58 / 271.
This is a project that has been mass produced.
This has not happened before, but now it has happened.
I bought these devices from Mouser.
Can you help me to analyse what is the reason?
I can send you schematic via email if you need.
Thanks.
