Hello again, The forthcoming upgrade of Electrum to 4.x will require python-trezor0.12 to maintain trezor compatibility. Is there someone that can upload that update? I tried contacting Richard Ulrich and Tristan Seligmann but haven’t been able to make contact. The primary roadblock to 0.12 was python-libusb1, which is now upgraded to 1.8 and should be compatible. Any help you can provide would be greatly appreciated Mike
