Hi everyone.

LPC-Link2 is favorite tool for me.

I'm using LPC-Link2 as a CMSIS-DAP debugger on MacOS X.
But I have faced a problem that Macbook air *often* does not recognise LPC-Link2(HID device).
# NG case is about 8/10. (Plug USB cable out and in.)

In the NO issue case, I can get the "LPC-Link-II" from system_profiler and LPC-Link2 works all right.
# system_profiler SPUSBDataType | grep LPC
            LPC-Link-II CMSIS-DAP:

- Macbook air : 2011 late, version 10.10(yosemite)
  # When I use mavericks, also this issue occurs.

- LPC-Link2 CMSIS-DAP F/W : v1.11_1 2013-12-05

When I use this LPC-Link2 and same USB cable on "Windows 8.1 update",
it always works fine as a CMSIS-DAP.

Anyone use LPC-Link2 on Mac OS environments?

Thanks,

Outcomes
