That’s right @Jay . I found the same on my device as well. I can see the ‘channel\_config’ file updated, when I ran the command.

`echo -n 1,2,-1,0,0,1,2,0,0,0,0,max6675 > /sys/devices/7c00000.hsic_host/usb1/1-1/1-1.1/1-1.1:1.0/channel_config`

I was going through @dfrey comments from another post [SPI access on Raspberry Pi Connector](https://mangoh.discourse.group/t/spi-access-on-raspberry-pi-connector/875/4). Probably intended for WP85. But, one thing - I am also using spiService to get the app talking to the SPI interface. So,

1. Will @dfrey’s comments (on the other blog post) hold good for me as well?
2. How will I reference the SPIdevice from the app? spidev1.1 (if chip select CS1 used)? If so, how to get this one instantiated from spiService? Does spiService need a rebuild with some modifications?
