TUSB4041I: TUSB4041IPAPR - Keyboard detection issue

Part Number: TUSB4041I

Tool/software:

Dear TI Support Team,

We have built the schematic and the layout based on the reference design for TUSB4041IPAPR and everything works fine with it. We are able to detect the mouse as well but somehow we are not able to detect the keyboard. We have tried keyboards from 3 different companies but non of them are recognised for us.

If we can get an email address we can share the schematic file as well. We cannot share it on the open forum.

We are interfacing this IC with the Raspberry PI Zero

Please advice
