Keepkey and Trezor may ask the user for confirmation of their passphrase after the PIN is sent. This could cause some issues as
ButtonRequests
were not being handled bysendpin
. Additionally,TrezorClient.call
would not work because it needs access toTrezorClient.features
, which is not set for thesendpin
command. In order to resolve this,TrezorClient.call
is modified to optionally skip the firmware check that requiresTrezorClient.features
, andsendpin
usesTrezorClient.call
instead ofTrezorClient.call_raw
.Fixes #526
Fixes $539
