raw mode firmware HID interface?
HID interface is also able for raw mode firmware, and all address is same as xvsm mode(W/R xvsm regs will do nothing). But for now, we have not do some test for control LEDs.
I had a try to control the LED, and the 8 channel recording device stopped working (win 10). I have to re-plugin the mic array.

if the 8 channel is stopped working after sending LED control commands, it might be caused by setting data operation. I will check it soon, thanks for your feedback.
put the mic array on your desk and make sure the USB is face to you. the central mic is 0th, the letf top one is 1th，then, anti-clockwise are others.
@foldl @Fuhua-Chen There are 8 output channels which outnumber the 7 physical microphones. What is the extra one suppose to be?
0-7 channel are physical microphones, the eighth channel is average of both 0-7 channel. XMOS official program uses channel 0 for average. 7 channels microphone data and 1 channel average can use for some simple application. eg: auto gain control.
