v.0.6.10 problems connecting

[ELM4Ever]

Just updated my python-trezor library from 0.6.6 to 0.6.10 - then started to have communication problem using Electrum (version 2.5.4).

File "/Library/Python/2.7/site-packages/trezor-0.6.10-py2.7.egg/trezorlib/transport_hid.py", line 54, in enumerate
raise Exception("Unknown USB interface number: %d" % interface_number)
Exception: Unknown USB interface number: -1

Same error comes up when using the example code in the repository Readme file. Therefore, problem is not with Electrum.

Reverted back to v.0.6.6 and it worked again.

Fucking OS X. Fixed in 915cf00 and released as 0.6.11

Thanks. It works now.

BTW: v0.6.11 is not compatible with protobuf v3.0.0. I understand that the latest stable version is 2.6.1, but if left unspecified in a setup.py file, protobuf will update to 3.0.0 (which is the case for Electrum). I have asked Electrum to force the download to 2.6.1, but you may also want to have a look at the issue with 3.0.0.

Just to let you know. python-Trezor 0.6.11 works with Electrum 2.5.4, but not version 2.6 (latest github head). They are looking at this issue.

python-trezor never worked with protobuf 3.x and I don't have plan to change this (because it would require changing the protobuf version used in the device itself).

There is a requirement on version 'protobuf==2.6.1' in setup.py of python-trezor: https://github.com/trezor/python-trezor/blob/master/setup.py#L32

Latest changes made to Electrum 2.6, combined to python-trezor 0.6.11 now work well (OSX).

Thanks.
