Hello,
I have configured the HX3 CYUSB3314 - 88 pin through the HX3 Blaster plus SW, and set the EMBEEDED HUB BYTE to 1, because my USB Upstream link cannot be removed by a user ( Embeeded in a product). My Hub is powered externally ( VBUS is not used) .
However, when i cut the Vbus Upstream wire to simulate a default, or a perturbation, the Hub detect it and disconnect. Is it the appropriate and expected behaviour ? What is the purpose of this setting ?
I'm currently using the ihx3_revb_b7 firmware.
Thank you for your help,

Hello,
Please let us know what is the current connection on VBUS_US pin? Does the hub enumerate when the pin is left unconnected from power-on?
Please refer to the KBA for details on the setting, it ideally shouldn't consider the VBUS on the pin for disconnect/connect.
Kindly also confirm if the modified settings have been programmed correctly onto the EEPROM by resetting the hub and reading back.
Best Regards,
Sananya
