https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=271012 Bug ID: 271012 Summary: FreeBSD kernel does not detect USB3.2 storage media on Windows Dev Kit 2023 USB-C ports (for example?) Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: email@example.com Note: the UEFI/ACPI stage and the FreeBSD loader.efi activity (that uses UEFI I/O services) have no problems finding and using the media. It is the FreeBSD kernel that has the problem below. Context: Windows Dev Kit 2003 is the known example. Context: main [so: 14] on/after Apr-18's 21d56b796634 The loader.efi based on such must be used. The earlier Jan-18's 896f556205c8 (kernel) is needed. Also: Need use of hw.pac.enable=0 in loader.conf . Context: USB3.2 media examples were Samsung PSSD T7 Touch's (2 GiByte and 1 GiByte) with cables for both USB-A and USB-C use. USB3.0 media examples were OWC Envoy Pro mini's (256 MiByte) USB-A connector. Context: It is not clear if this is aarch64 specific or not. I've no other test context for it. In testing the 2 types of USB3.* media that I've access to, The USB3.2 media are not detected by the FreeBSD kernel when connected to the USB-C ports (but are detected when connected to the USB-A ports): USB3.2 in USB-C port (no "umass0" or no "umass1" or . . .) USB3.2 in USB-A port (works) USB3.0 in USB-A port (works) Unfortunately, I do not have a way to form a USB3.0/USB-C combination. The fact that UEFI handles all the combinations leads to USB3.2 in USB-C as root media ending up with the kernel unable to mount the root file system, for example. But, if the boot does not need the media, it is just as if it had not been plugged in, no boot -v messages about the media at all. (May be the Windows Dev Kit 2003 makes for a good context to use in the effort to modernize the USB support in FreeBSD?) Side note: https://learn.microsoft.com/en-us/windows/arm/dev-kit/ reports: QUOTE When connecting an external keyboard or mouse, use the USB-A ports, not USB-C. Using USB-C to connect a keyboard or mouse will only work intermittently. END QUOTE That is not what this report is about. (Also: It is unclear if that note is about UEFI vs. Windows vs. it being more general.) -- You are receiving this mail because: You are the assignee for the bug.
