I cannot understand why Dell continue to not doing something? Just see image attached and check this forum. Avast have free antivirus with some file "ASWKBD.sys" which may reference with the bug. https://forum.avast.com/index.php?topic=153516.0 Dell engineering sleeping instead some how block Avast at least. Dell you need to make drivers for Win 10 x64 due to this fiasco from Avast.

Finally I find solution. Seek for registry "EnhancedPowerManagementEnabled" and set it to zero (0) in "Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB"

"Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceMigration\Devices\USB"

 

For example:

"Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_046D&PID_C52B&MI_00\6&14ae97d5&1&0000\Device Parameters\EnhancedPowerManagementEnabled" Just search for usb vid number and disable EnhancedPowerManagementEnabled. Then restart PC and everything should be fine.
