Dear All,


I'm using iMX6Q for development product.


Problem Status:

1, We use Host 3 to connect USB HUB(SMSC USB4604), And HUB of USB4604 have a HW reset pin.

2, When I force USB4604 over HW reset pin, USB Host 3 will hang on 4 minutes.


That hang on 4 minute look like define by code.

We want to decrease USB hang on 4 minutes period,

Does any one know where can modify that 4 minutes value?
