USB and Core22 and Snap
Metadata
Current evaluation
Closed as Invalid by maintainer mr-cal: USB device visibility on Core22 is a snapd runtime/interface problem, not a Snapcraft build bug; reporter directed to the Snapcraft forum and asked for Snapcraft error logs.
Resolution: closed not a bug
Reason: No Snapcraft code change was made or needed. Maintainer mr-cal closed the report labelled 'Type: Invalid' on 2025-04-21, stating snapd runtime issues belong on the Snapcraft forum and asking for logs from an actual Snapcraft error before a bug would be tracked; searches of the snapcraft repo found no matching commits or code references tied to this report.
