https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=258057 --- Comment #26 from Dan Kotowski <firstname.lastname@example.org> --- I believe that Bjoern and I have earlier revisions of the boards, while Mark has a more recent one. And I know Solid-Run had to fix at least 1 USB erata (flipped TX/RX on 1 port) so I can imagine there may be others. Of note, jnettlet has mentioned the following: """ I have [usb powersaving] turned off on all my boards. Synopsis did have a bug with powersave and hubs in their IP which we have the errata workaround enabled for...but even then some devices are just flaky a patch is merged in [Linux]. the feature is called parkmode I am setting that in UEFI though. Unless maybe BSD is re-enabling it """ If it helps, this is the raw DSDT ASL for the USB parts of the firmware: https://github.com/SolidRun/edk2-platforms/blob/24698f90b79facfbbfc4067b39a4ddf8c7fdfa88/Silicon/NXP/LX2160A/AcpiTables/Dsdt/Usb.asl You can easily see it setting `snps,dis_rxdet_inp3_quirk` - perhaps we ignore or unset this? https://github.com/torvalds/linux/blob/835d31d319d9c8c4eb6cac074643360ba0ecab10/drivers/usb/dwc3/core.h#L1065 * @dis_rxdet_inp3_quirk: set if we disable Rx.Detect in P3 -- You are receiving this mail because: You are the assignee for the bug.
