bump, same issue....
Someone told me that electrum uses an old python library for trezor in its binaries. I tried PMing thomasV to confirm but no reply.
ive temporarily moved my hot btc to nano S. Slightly more annoying to use... but it works atleast.
Did you ever hear back? I am having the same problem.
Electrum 3.0.2
Firmware 1.5.2
negative.
im just using my nano s fine. when trezor works again ill re-evaluate.
you can roll back your electrum to version 2.7x or something. It works fine
