Tablet hangs after waking up from Sleep

Hi Team,

I am trying to test Windows 8/8.1 Connected Standby feature using one of  my custom USB HID device and samsung windows 8 tablet. I am able to get the Sleep notification on the USB since the bus is suspended. However, when I try to wake up the tablet the screen is hanged. I cant access any controls. 

One thing I know for sure is my device is drawing much higher current even when suspended (> 2.5mA as mentioned in spec). Will the Win 8 host disable USB port on over current condition?

Also, as per below link transitioning out of standby is responsibility of device and not host? My device does not support remote wake up. In that case when host is out of Sleep it should still start communicating with my device, right?

Please provide some inputs

Hi,

Regarding the remote wake-up feature,it depends on the hardware.

I suggest you contact Samsung support to confirm this feature.

If the hardware supports this feature, I suggest that you check the event viewer to see if some error log appeared when the occurred.I suggset you contact Samsung support for helps.
