Due to a protobuf requirement of a very outdated version of keepkey library which electrum has fixed already but electrum-ltc hasn't you need to install an old version of protobuf to be able to use the keepkey hardware wallet.

Due to an incompatible upgrade to trezor libraries, to be able to use the trezor hardware wallet you need to install a version of python-trezor < 0.13.10
