Thank you for the details. The problem is fixed: xaionaro-go@17c90e8

If the device is not initialized:

$ ./gocryptfs -trezorkey -init /tmp/1
Choose a password for protecting your files.
Cannot reset the Trezor device. Error: The wallet device is not initialized.

If the device is initialized:

$ ./gocryptfs -trezorkey -init /tmp/1
Choose a password for protecting your files.
PIN: 
Passphrase: 
The gocryptfs filesystem has been created successfully.
You can now mount it using: gocryptfs /tmp/1 MOUNTPOINT
