Libusb application can't access device even after the raw-usb interface is connected

I assumed there’s some kind of magic occurred in snapd that makes this possible :man_shrugging:.

I can successfully access the device after running the command as root, but encountered another problem: The snap can no longer access regular files under my user directory (assumed due to the $USER is now root, which makes my home directory out of the sandbox). As this behavior is clearly inconsistent with classic applications(which root can access everything) is there any way to workaround this issue?

EDIT: No longer a problem: https://forum.snapcraft.io/t/libusb-application-cant-access-device-even-after-the-raw-usb-interface-is-connected/23069/10
