Part Number: TUSB2046B

Hello ,

I am using "TUSB2046BIRHBR" USB-HUB,

Actually i have connected 2 down streams to my USB-HUB  remaining 2 ports unsed.

When i see logs of USB-HUB i can able to read only 1st Down strem port  device,where as in logs 2nd port device is not showing.

So how can i solve this 2nd down stream port issue.


i have verified differential pair signals of 2nd down stream port,VCC power,and all neccessary connections but still its not showing in logs.

EVEN at DP (D+) signals of down stream  i can measure high  (3.3v).

but still 2nd device not showing in logs.
