For the most part HIDs like keyboards and mice are = reliable, but data transfers from mass storage devices can sometimes, = though not reproducibly, cause the xHCI controller to reset. For me keyboard/mouse sometimes worked after reboot/detach<->attach, = sometimes worked not(using Original RPI4-power adaptor). As seen in = dmesg I could mount USB thumb drive. I suspect the generic_xhci driver(s) for the problems and I guess there = some =E2=80=9Aquirks=E2=80=98 have to be added there(also for ACPI)... I will test it in more detail and then publish it in the wiki if you = don't want to do it yourself in the wiki. > I have only tested it against the soldered-on xHCI chip; if anyone has = desoldered it and replaced it with a pci-pci bridge, that would be = interesting to hear about. >=20 > Before I submit this to phabricator, assuming there is interest, I = would be interested to hear others' experiences with it, or indeed any = other feedback. > _______________________________________________ > freebsd-arm@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-arm > To unsubscribe, send any mail to "freebsd-arm-unsubscribe@freebsd.org"
