Software Installation
2.3 Windows 8.1 and Windows 10 USB Selective Suspend Setting
The Windows 8.1 and Windows 10 operating systems issue a suspend command to a connected
USB device if there is no activity on its USB bus. This may happen to the BLE Pioneer Kit/BLE Don-
gle if the driver installation is not complete or the driver is not found. In this situation, as a response
to the suspend command from the operating system, the KitProg will shut down the onboard LDO to
remain within the USB suspend current requirement. Due to this, the BLE Pioneer Kit will not be
powered and will not be functional.
To prevent this, do either of the following:
Install the kit software on the Windows 8.1 or Windows 10 operating system before using the BLE
Pioneer Kit.
Disable the USB selective suspend setting for the BLE Pioneer Kit from Power Options on Win-
dows 8.1, by following these steps:
a. From Control Panel, go to Power Options.
b. Click Change Plan Settings corresponding to your power plan.
c. Click Change Advanced Power Settings.
d. Under Advanced settings, expand USB Settings > USB selective suspend setting.
e. Select the Disabled option for Plugged in and On battery operation.
f. Click OK.
