Seems to work when testing with Electrum, although I haven't tried actually doing anything apart from confirming that the device is recognized. As noted by maintainer, trezorctl fails because of missing python3-construct. Installing that from COPR fixes it, so it should work when the new version gets uploaded. Thanks for updating this package!
Unfortunately this seems to not be installable because of missing dependencies:
Error: Problem: conflicting requests - nothing provides python3.7dist(pyblake2) >= 0.9.3 needed by python3-trezor-0.11.4-2.fc30.noarch - nothing provides python3.7dist(shamir-mnemonic) >= 0.1.0 needed by python3-trezor-0.11.4-2.fc30.noarch
The newer version supports OpenSSL 1.1. Changing the BuildRequires should be enough to make it use the new version.
Thanks so much for updating this!
