600mA is really high. And it surprised me. It was like that for about 30 minutes. And then dropped to 24mA. It's 24mA now. It was odd to me that the board drew so much current when I first plugged it in. It worried me when the StereoCodecControlSoftware.exe software wasn't connecting.
I was following your instructions online
https://www.nxp.com/docs/en/user-guide/KTSGTL5000UG.pdf
Which appeared to require the driver to be a FT2232C Channel A and FT2232C Channel B, which it was not, it was coming up as a com port. So I thought I was doing something wrong.
I downloaded the latest FTDI D2xx drivers, and followed your instructions but when it got to what driver was installed, I let it show up as a com port, and continued and it did work. They show up as 2 com ports, not the channel a and b, but the StereoCodecControlSoftware.exe software is now working and connecting.
Thanks.
