Electron-Cash: "cannot pair trezor" with Electron-Cash-4.1.0-fusion

using Electron-Cash-4.1.0-fusion-1-74-g12dd3338e-x86_64.AppImage I cannot pair my trezor.

electroncash.plugins.DeviceUnpairableError: Electron Cash cannot pair with your Trezor.

Before you request bitcoins to be sent to addresses in this wallet, ensure you can pair with your device, or that you have its seed (and passphrase, if any).  Otherwise all bitcoins you receive will be unspendable.

I verified passphrase is correct by using older, non-cashfusion version (tried many times)

I’ll also do some testing with Keepkey and Ledger.

    Refactor mnemonic.py; resurrect BIP39 seed generation

I didn’t regenerate python env between steps, I hope that’s not the issue.

Edit: I hope we don’t have to keep that old mnemonic implementation around just for trezor?!?
