Is USB Vendor ID needed to sell custom USB-hub based on IC?
The TI TUSB4041I IC comes with a pre-programmed vendor/product ID, namely 0x0451 / 0x8140.

According to the data sheet:


  The value may be overwritten to indicate a customer vendor/product ID. 


My interpretation of the statement is that it's ok to leave it at the preprogrammed value.
