Hi,

First of all check if your schematic complies with these guidelines: processors.wiki.ti.com/.../AM335x_Schematic_Checklist If possible post the USB section of your schematic.

What is this hub? Is it an external device?

Please describe what exactly the hub does not operate normally.

Please also test the latest Processor SDK on BBB to see if the issue still exist.

MBF-H04 is the usb hub.

If USB stick is plugged into hub and connected to BBB, usb stick is not recognized.

If you connect the USB stick directly to the BBB, will it work? (without the hub)

yes
