Hi,
I'm using electrum 2.9.3 on macOS sierra with a ledger nano s.
I can't import my wallet, after selecting the wallet derivation "Cannot read xpub from device" error appears.

I have the same Problem
Same problem. Electrum 3.0.0 / macOS Sierra
Update the Nano to firmware 1.3.1 and the Bitcoin app to 1.1.10 and try again. Might just be old versions on the Nano S that don't play well with Electrum.
Thanks for the help, however I already have 1.3.1 and 1.1.10
Same here, already updated to 1.3.1 and 1.1.10
