About this tag
USB-C diagnostics in Windows 11 focus on ensuring that the operating system can reliably detect and report issues with USB Type-C connections. Microsoft is urging PC manufacturers to implement proper platform-level hooks, including accurate ACPI descriptors and UCSI/UcmCx firmware and driver paths, so that Windows can deliver clear notifications about problems such as slow charging or display failures.
