Failed to connect to the chosen device

[ibrokemypie]

Describe the bug
Trying to use zmk studio to configure my sofle keyboard on linux but whether I use the appimage or chromium I just get the same non-descriptive error when attempting to connect to my keyboard.

To Reproduce
Steps to reproduce the behavior:

1. Compile and flash firmware with cmake-args: -DCONFIG_ZMK_STUDIO=y -DCONFIG_ZMK_STUDIO_LOCKING=n
2. Connect keyboard over usb
3. Hit the &out USB bind
4. Open zmk studio
5. Pick keyboard

Expected behavior
It works

Screenshots

Environment (please complete the following information):

• OS: nixos
• Browser or App: either
• Version: 0.3.1
• Device: choc sofle

Additional context
I also have the groups uucp, plugdev and dialout, and a udev rule to give access to the usb device in an attempt to get this working, but it made no difference:
SUBSYSTEM=="usb", ATTR{idVendor}=="1d50", ATTR{idProduct}=="615e", MODE="0666", GROUP="plugdev", TAG+="uaccess"

Also having this same issue on Fedora and Arch linux. Same deal, checked all groups, tried taking ownership of /dev/ttyACM*, same non-descript error on both appimage and browser

so my issue, with the Eyelash Corne, ended up being a firmware configuration issue. I've forked the Eyelash Corne and made some changes to fix it and am now able to use it. https://github.com/safwyls/zmk-eyelash_corne

It's also worth noting, when connected I see two serial devices, ttyACM0 and ttyACM1 and only the second one will work with studio. The first appears to be reserved for usb serial logging.

Make sure your user account is a member of the dialout group, permission denied usually means you aren't

thanks @JeromeTDev launching zmk-studio from terminal with sudo, fixed the issue!
