Error: Extended public key export cancelled by user

[SebastienGllmt]

I'm trying to run the following command on my Trezor device on the latest version of cardano-hw-cli and latest Trezor firmware

cardano-hw-cli node key-gen \
 --path 1853H/1815H/0H/0H \
--hw-signing-file ./cold.hwsfile \
--cold-verification-key-file ./cold.vkey \
--operational-certificate-issue-counter-file ./cold.counter

The device then prompts me to enter my Trezor passphrase, but after I enter it and accept I get Error: Extended public key export cancelled by user which seems to come from this code

Any idea what the issue could be? Cardano-hw-cli swallows the original error message, so it's hard for me to know what is going wrong

Hi, I think this is caused by the fact that Trezor doesn't support 1853' path derivation (as well as signing pool registration transactions as operator), as noted here.
