Failed to run bf_sde by Error: Unable to open CP2112 devices

[hiroki2]

We use Wedge100BF-32X as Intel Tofino(1) switch.

I setup this swith by SONIC that download from https://sonic.software/ 's master branch image.

Then, I build bf-sde-9.13.0, install bfnsdk_1.0.0_amd64.deb and bfnplatform_1.0.0_amd64.deb, tried to run switchd.

But an error occured.

```

```

Using Accton Diag(https://support.edge-core.com/hc/en-us/articles/900000750703), I successfully run switchd as testing switch device, on SONIC with bf-sde-9.13.0, I got an error.

How can I solve this problem and run switchd?

Hello, thank you very much.

I'm still in trouble about this error.

Then, to contact to barefoot team, I tried to join Intel® Connectivity Research Program (Private).

https://community.intel.com/t5/Intel-Connectivity-Research/cmp-p/grouphub:connectivity-research-program

This group has a lot of knowledge about Tofino and barefoot team was joined.

But my request to join this group is not approved yet and it displays "Your request to join was sent August 23, 2023
You will receive a notification if your request is approved.".

How can I join to this group?

I'm waiting for your great support. Thank you.
