Don't mess around with your Trezor seed words - the problem is not with your Trezor. There is no need to wipe it either.
I would suggest to first ensure that you have the latest Electrum.dmg file from electrum.org
Next, open Finder, then select GO --> GO to Folder
Enter ~/.electrum in the window that appears.
Within the ./electrum directory, erase the config file. Also move (or rename) all the wallets in the wallet sub-directory. Don't worry, your private keys are in your Trezor, not on your computer. The only thing you may loose by erasing an electrum wallet file that was created for a Trezor, are the labels you gave to each transactions. If you don't want to loose that info, just rename or move the file(s) somewhere else.
Start Electrum and create a new Standard wallet, with the Hardware wallet option. If Electrum can communicate with your Trezor and create a new wallet at this step, your problem is solved and you should be good to go. If not, you have a problem with your USB cable. The cable supplied with the Trezor is notorious to be of bad quality. Spend a couple of $$ and go buy a good one and that should fix your problem.
EDIT: If the creation of the main account (m/44'/0'/0') worked, then you can proceed to create the second account of your Trezor (since it looks like you had setup two accounts on it). The second one should have the derivation of m/44'/0'/1', if you have a third account, m/44'/0'/2', etc. They now have to be different files for each account, make sure you name them accordingly, when you create each new Electrum wallet file.
I already did this, every wallet after m/44'/0'/2' is empty
