trezor one device not detecting on electrum-3.0.6/3.1.0 python tool

[sharath1990]

I am using latest python-trezor v0.9.1 and electrum-3.0.6/3.1.0 wallet but that electrum wallet not able to detect trezor one device. it says AttributeError: module 'trezorlib.client' has no attribute 'types' and AttributeError: module 'trezorlib.transport_hid' has no attribute 'DEVICE_IDS'
only python electrum tool is not able to detect the device but electrum windows tool is able to detect it.
Please check with issue and resolve it as soon as possible.

python-trezor 0.9.0+ will only work with electrum 3.1.0+

Make sure python-trezor is installed for python3, and perhaps try uninstalling it "multiple times" until pip says it is not installed, and then install it again, to make sure only the version you want is installed.

If you are getting either of those errors with python-trezor 0.9.1 with electrum 3.1.0, then please provide a trace.

[SomberNight]

What do you mean by "python electrum tool"?

[sharath1990]

its means the source code language used for electrum bitcoin wallet is python.

https://electrum.org/#download
In the above link you have "Installation from Python sources": in that you have windows tab and i am using Install Electrum-3.1.0.zip

[SomberNight]

Using the same python interpreter you are experiencing the issue with, what does the following print:

python3 -m pip show trezor

[sharath1990]

[SomberNight]

Could you describe a minimal example of how to reproduce the errors?

[sharath1990]

Yep,
Just go to Electrum-3.0.6 folder path in command line and type "python electrum" click enter and gui will be opened in that click next and select "standard wallet" and click next and select "Use a hardware device" and click next that's it. error will be produced.

[SomberNight]

Just go to Electrum-3.0.6 folder path

Again, as I said:

python-trezor 0.9.0+ will only work with electrum 3.1.0+

[sharath1990]

even if i used Electrum-3.1.0 same issue i am getting.

[SomberNight]

See #3928

Please provide a stack trace for the error you are getting because I cannot reproduce.

[sharath1990]

if i use Electrum-3.1.0 i am not getting AttributeError, but device is not detecting, plz find the screen shots that i tried are electrum-3.0.6 with python-trezor v0.9.0; electrum-3.1.0 and python-trezor v0.9.1; and other combination.

[SomberNight]

Forget about electrum 3.0.6; that error is expected; only test with electrum 3.1+.
Do you have proxy settings enabled in Electrum? Please try with 3.1.1.

[sharath1990]

what do you mean by proxy setting?

[SomberNight]

I mean a networking proxy set up inside Electrum:

There is a bug related to that and hw wallets in 3.1.0;
but regardless, please try with 3.1.1

[sharath1990]

Still not works.

[SomberNight]

please try with the -v flag, and provide logs
python electrum -v

[sharath1990]

yeah done.

[SomberNight]

Just to be clear, it works with the official binary, but not when running from source?

[SomberNight]

I believe you are missing the libusb dll; that raises an exception, and all transports for trezor fail.
78a9424
If you want to use the webusb transport, you will need to make sure python can import the libusb dll.
You can e.g. manually download it and place it in the root python folder.

In any case, we should minimise the problem and not let all the transports fail.

[SomberNight]

Please try on current master. :)

[sharath1990]

I took the current master branch & installed respective packages but it still not works?

[SomberNight]

Did you run python setup.py install? As in https://github.com/spesmilo/electrum#development-version

[SomberNight]

Please follow the guide I linked above; that too is covered there.

[sharath1990]

after this step 'python setup.py install' still it not works for me.

[SomberNight]

please run with -v because without logs it is a black box, literally.

[sharath1990]

okay.

[SomberNight]

Can you confirm that it works with the official binary?

[sharath1990]

what do you mean by official binary?

[SomberNight]

I mean the exe files at https://electrum.org/#download

[SomberNight]

Ok, I can reproduce. It's still libusb somehow.

[SomberNight]

Ok, for the moment, I suggest downloading the libusb dll, and copying it to your python path (e.g. %localappdata%\Programs\Python\Python36-32\); as we do for the binaries in 78a9424.

The problem is that python-trezor 0.9.0 and 0.9.1 (but not the current master) import all the transports :/

[SomberNight]

See trezor/python-trezor#218 (comment)

[SomberNight]

Ok, it should now work on current master.

[sharath1990]

yeah, it works thanks.:)
