2015-08-06MdeModulePkg/Usb: Adjust TPL to not block async transfer during usb enum.Feng Tian
EDKII usb stack is using a TPL_CALLBACK timer to monitor async transfer request and signal event if it's done. As usb enumeration and usb mass storage block i/o read/write runs on TPL_CALLBACK and TPL_NOTIFY level respectively, It blocks usb async transfer requests, usually usb mouse /use kb, getting time to run. Without this change, user couldn't get usb mouse/kb state in time (will show a little lag from UI view) when there is other usb transactions, such as a new usb device inserted.
