Cannot detect device

[patnir]

I am able to install the app on device and delete the app using the VS Code extension.

Running Quick initial device setup cases the following error (even though I did open the right application)

Traceback (most recent call last):
  File "<frozen runpy>", line 198, in _run_module_as_main

ledgerblue.commException.CommException: Exception : Invalid status 6d00 (Unexpected state of device: verify that the right application is opened?)

Running Run tests with display - on device produces the following errors:

I am using an M2 mac. I have a ledger nano S plus. I am using the Ledger VS Code extension.

I have the same problem (device not found) lauching the command:
cargo ledger build nanosplus --load
, which seems to be the docker being unable to forward the usb. While in the docker, typing ledgerctl list, or lsusb, nano is not recognized.

I tried to add permission related to usb while launching the docker:
sudo docker run --rm -ti --privileged \
--device=/dev/bus/usb:/dev/bus/usb
-v "$(pwd -P):/app"
ghcr.io/ledgerhq/ledger-app-builder/ledger-app-dev-tools:latest

But still got an error.

On Windows and MacOS, we have some issues accessing usb devices from the Docker instance. Ragger tests should be performed with speculos. To test on real devices, one way to proceed is to get the APDU sequence sent to the device (you can get it by running Ragger test with the -s option), put them in a file (test.apdu) then, after installing natively ledgercomm on your OS (pip install ledgercomm) and the app on your device:
ledgercomm-send --hid file test.apdu

Thx a lot, i didn't get that i could load the app using ledgerctl. So maybe for macOS users, the section "loading" shall be replaced by the command:

ledgerctl install app_nanosplus.json

(As it is documented in the starknet application).
