USB Hosts Hubs Transceivers

Hi,

   

We are using CY7C65642 USB hub IC (self powered mode) in our design.We are working with i.MX6DL along with Linux and testing low power mode functionalities.

   

We observed that,current consumption is getting increased after connecting a usb device(like pendrive) even at low power mode of iMX6DL.

   

We have a couple of clarification and mentioned below

   

1.Is the increased current consumption in low power mode (after connecting pendrive ) expected behavior or not?

   

2.We would like to know whether there is any option to make the USB hub IC and ports to suspend mode

Yes, the power consumption may increase if you plug in a device even when it is in low power mode.
