6 months ago Hey sorry for not responding sooner. I get so many notification from github this one got lost in the noise.
I will need to have a look at the docs again for the MCP2221 device, its been a while since I looked at this code.

Next build 2.0.0 will resolve this problem.
I have also upgraded the runtime as net app 3.1 is no longer supported by MS
Hi, This is perhaps more a question than an issue, as I might have misunderstood the usage of the library.
I'm trying to use the smbus commands (read-byte-command and read-int-command) towards a PMBUS-device on address 0x53. I try to read the 'CAPABILITY' register (0x20) but I always get "Unexpected response code".
Am I doing this wrong?
