Hello NXP

Is the usb pause mode available when connected to an Android phone/tablet?

I have implemented the USB suspend function on our device and it works fine

my usb devices can be suspended/resume when connected to the host PC

but when I connect to the Android phone, the usb device is always running, and will not enter the USB suspend state

How to configure the usb library to support usb suspend on Android devices? Or is this problem based on the Android configuration?

 

Thanks

Robin

Hi Robin,

We do not have specific configuration for Android devices in our USB stack, therefore, I think the problem could be on the Android side, maybe there is a some driver missing.

Best regards,

Felipe
