Unable to connect device for Firmware tools #4

Closed reikrom closed 1 year ago

reikrom commented 1 year ago 
Uni v4
Chrome Version 109.0.5414.119 (Official Build) (64-bit)
Running on Fedora 37
Firmware works after using builder tool
Device shows up

image When I try to connect I get NotAllowedError: Failed to open the device. Screenshot from 2023-02-11 00-27-19

I went to chrome privacy settings and made sure HID, USB, and port permissions are not blocked as per google FAQ. Chrome dev console doesn't have any other errors.

Works on mac os, Closing as it's a Fedora issue

Solved. open chrome://device-log/ found [11:37:51] Failed to open '/dev/hidraw2': FILE_ERROR_ACCESS_DENIED ran sudo chmod 777 /dev/hidraw2

Great! You can also set up a udev rule like:

SUBSYSTEM=="hidraw", ATTRS{idVendor}=="9000", ATTRS{idProduct}=="400d", MODE="0666"

And it'll have the correct permissions even after disconnecting/reconnecting or when rebooting.
