Hi Johan,
Johan Hovold 於 2018/1/10 下午 04:49 寫道:
Normally, the communication with F81534 ep0 will take less than 1 sec
(even only some milliseconds), but It maybe take much long time with
huge loading with UART functional.
We had tested it on BurnInTest, 4 ports with 921600bps + MSR status

Hi Johan,
In this code, I'm only read/write 3 registers of 0x2ae8, 0x2a90, 0x2a80,
but some register will read/write more than once. Should I change the
code from port_probe() to attach() and re-write it as:
1: read the 3 register
2: change them will 12 pin desire value
