Hello E2E,
Please help to review TUSB2046B sch as attachment.
The one port of TUSB2046B will connect to a certain module while another one will connect to USB connectot.
Beside to the sch review, there are three questions listed in below.
Q1: What is the main function of GANGED pin as pin 6?
Q2: For pin8, if customer wants to use self-powered mode, could customer pull pin8 to GND or need to through a series resistor 2.2k to GND?
Q3: regrading to VBUS, since DM0, DP0 and DM1, DP1 connect to a chip, so it doesn't need external VBUS(5V). Please advise.
