[vikashkumar]

Hello ,

I'm working on KDS1.3 USB Host stack with HUB.Stack is working fine with 1 usb(without hub) but, when i connect hub,then i'm getting  1TR Timeout error in khci.c file.

Any idea on what could be happening?

Thanks,

Hi vikash kuamr

I highly recommend you to use our latest USB stack, it is included with the SDK 2.x package.

Please check the following post:

Kinetis Design Studio USB "3TR Timeout!" in khci.c 

It recommends to disable MPU on the main startup.

Hope this could help you.

Best Regards
