MetaMask Wallet with Trezor One // no confirmation query is showing on the Trezor // can't move funds

Hi there,

I secured my MetaMask Wallet (chrome extension latest version) with my Trezor One (latest Firmware Version). When I try to send funds out of the Trezor Account of the MM Wallet the confirmation query doesn’t appear. So there is no possibility to confirm the transaction on the Trezor.
Any ideas with that kind of issue ?

Is it possible to recover the Trezor secured MetaMask Account on a different Computer by connecting the hardware wallet with a newly installed MetaMask extension or is this overwriting any private key already stored in the Trezor device ?

Hence I was able to process some transactions a few days ago, I can asure that I know my password etc.

Any suggestions would be very appreciated!
