This is unnecessary and has nothing to do with sending from Coinbase to Trezor. You should only do this step IF the token name doesn’t show up automatically AFTER you successfully send it to the Trezor.

You are copy/pasting the entire address, correct? This should absolutely work, and again, has nothing at all to do with Trezor. You are simply sending your coins to an address, and CoinBase has no way of knowing if that address is associated with a Trezor or not.
