I just tried all these combinations. The wallet is "detected", however it will not pair.

I noticed that when I paired the wallet to electrum, the wallet had a different name. I had renamed the trezor since pairing. I switched back to the name that the electrum wallet expected, but pairing still did not happen.

Are there debugging commands I can try to figure out the next steps? Should I contant trezor support?

Might need to try contacting Trezor support on this one... I've just tried a couple of quick tests with Electrum+Trezor ONE (I don't have a "T")... I created a 2-of-2 Multisig using the Trezor as one of the co-signers... then shut it all down and "renamed" the device in Trezor Suite... Then I disconnected everything, started Electrum and tried to open the MultiSig... Electrum still asked for the device labelled "OldName", but when I connected and unlocked the device with "NewName" it was still able to pair with the device and the wallet was available without issue.

I was even able to "restore" a copy of the multisig wallet by using the xpub+TrezorOne... and it created a wallet with the same addresses etc.

So, either this is some sort of Trezor T specific issue... or something else has happened with your setup to cause it to think that the wrong Trezor device has been attached. Do you have "passphrases" enabled on your Trezor device? If so, is there a possibility that when you first setup the MultiSig you unlocked the device using a non-blank passphrase? Huh

Anyway, I see you have also created an issue on the Electrum github issues register: https://github.com/spesmilo/electrum/issues/7314

Hopefully between them and Trezor support you can figure out what the issue is.
