Other Parts Discussed in Thread: TPS2044
I have the first development on TUSB2077A. I designed the circuit from datasheet Rev. F on page 16.
when I connect the hub to my host PC, my PC can't detect the usb hub.
On the hub, it show only PORTDIS light on. I have checked UP_DM and UP_DP they are connected to the chip pin with 28 ohm and DP0PUR connected to UP_DP with 1.5 ohm.
Now I don't know what to check next?
Please tell me what I must to check next.
Thanks.
