HI Brian 

The TUSB1210BRHB ULPI  IC using we facing the issue PIn 17 CPEN pin not getting High, so the VBUS not getting 5V  , Please help me here When CPEN will get high ?

• ULPI input CLOCK  this is fine ?

Hi

  It''s hub issue or TUSB1210 issue.

  For TUSB1210,  refclk ,looks ok. How did you control RESET signal?

  Did you configure TUSB1210 as host with firmware? for host,  ID is <1k, but not 0 ohm.

Regards

Brian

Thanks Brian, 

 The device tree wrongly configured USB0 instead of USB1 now the enable pin issue solved 

 We are just making reset pin high from processors 

Yes TUSB1210 configured host , also change ID pull down <1k

But TUSB8041 hub not detecting continously .some time not detecting after numer of turn on power after detecting hub.

Why hub behave like this ?

Hi Venkatesan:

  Is this the same ticket as this one?

TUSB8041: TUSB8041IRGCR USB 3.0 and USB 2.0 - Interface forum - Interface - TI E2E support forums

   So  FPGA  doesn't have DP/DM pin so you have to use  TUSB1210 to connect hub DP/DM?

Brian

Yes Brain same query only,

Yes fpga doesn't have direct dp/dm pin we added TUSB1210 IC

Ok, Let's discuss the issue together  during the call.

Hi Ben,

It seems the issue persists. We've isolated the USB Hub TUSB8041IRGCR and connected the USB connector with the pen drive using the TUSB1210BRHB ULPI IC, but the pen drive is still not being detected.

so the issue is TUSB1210 not configured correctly?
