+comments:
+ryan: 04/01: bit0 could disable lpdn dma, which is good at debugging while async_fifo have problem,    we could disable this and check the fifo_rcv_size to see if we have correct at fifo or not
+LP - lo priotiry; MP - middle priority; HP - High priority;

+
+# 0x110 ZM_SOC_USB_MAX_AGGREGATE_OFFSET
+    set stream mode packet buffer critirea
+    0x0 = disable stream mode or 1 packet. So 0x9 is 10 packets?
+# 0x114 ZM_SOC_USB_TIME_CTRL_OFFSET
+    set stream mode timeout critirea. the unit is 32 USB (30Mhz) clock cycles.
