"**Failed to find a TREZOR device.**" #282

Closed gatineauio closed 6 years ago

gatineauio commented 6 years ago

Trying to run trezorctl on Raspberry PI 3 and I get "Failed to find a TREZOR device."

I've added UDEV rules to be safe. I'm running as the commands using sudo and have all the latest packages installed. I've tested the device on another machine and it works just fine.

Unsure how to proceed.

please post output of trezorctl -v list

Is this a Trezor One or Trezor T? If it's model One, you need hidapi libs, maybe you don't have these?

gatineauio commented 6 years ago

It is the original model One.

I get an error when running the command trezorctl -v list: "Failed to import module hid: No module name 'hid'.

sudo pip3 install hidapi?

gatineauio commented 6 years ago

installing hidapi seemed to have resolved -- oddly it took over 20 minutes to install.

Thanks much. Does it make sense to make the error more verbose?

Again, thanks very much. Awesome response time.

Right now, only Trezor One needs the hidapi libs, and only on systems that don't have Trezor Bridge installed. And we expect to release a webusb upgrade to the T1 soon, so it won't need hidapi at all. (that is why hidapi is now optional, and that is probably why you didn't have it)

It might make sense to put an explanatory line if no device is found and hid libraries are missing, but it's low priority.
