/*!< Definition for enabling Link Power Management(LPM) function.
LPM related handler will raise after LPM event happen.
if bcdUSB >= 0x0201, USB version is equal or higher than 2.1,
OS(Windows) will issue "get BOS descriptor" request to check the support of LPM.
Notice:
If bcdUSB >= 0x0201, where USB version is equal or higher than 2.1,
WIN8 ~ WIN10 will fail to enumerate the device if device stalls the "get BOS descriptor" request.
WIN7 can still enumerate this device even though the "get BOS descriptor" request been stalled.
