For the people who aren't used to compile code from the command line, you could perhaps mention that the dev packages of libusb-1.0 and libudev are needed in order to compile the hidapi package (which is part of what happens when you run `pip install --user trezor_agent`)?

In my case, this was the full sequence of commands needed til install it (on Ubuntu 16.04.2 LTS, which is what you get when installing WSL on Win10):

`sudo apt update`
`sudo apt install python-pip`
`pip install --upgrade pip`
`sudo apt install libusb-1.0-0-dev`
`sudo apt install libudev-dev`

Thanks, this is the right answer so I accepted it but I can't get it to work. Also the README looks a little stale (there is no gpg-agent branch anymore). I just get `gpg: can't connect to the agent: IPC connect call failed` so I guess I will wait for the next round of dev.

(`trezor-agent` developer here...)

Please take a look at the latest `trezor-agent` version [here](https://github.com/romanz/trezor-agent).
I'd be happy to fix any issue with the documentation, and extend it with more examples to make it more helpful for first-time users :)

**EDIT**:
Make sure to install all the required packages as described here: <https://github.com/romanz/trezor-agent/blob/master/INSTALL.md>
