@phessler is there something I should see in a dmesg that says this is a broken-now-hopefully-fixed webcam so I can compare before/after?
@ed1conf sadly, nothing you can compare in dmesg. All of the devices attached, but anything attempting to use isoc mode on xhci would have errored.
@phessler Feels like some pretty big strides in OpenBSD the last few years.
@phessler This is huge. You rock! 😃
@phessler
A few other things like printers, scanners and smartphones 
Can't wait being back from work to test it 
@julianaito @phessler I believe mtpfs, printers, and scanners use bulk transfers rather than isoch transfers and should already have worked beforehand.
Isochtransfers are only used for real-time streaming of data where periodic refresh is more important than occasional data loss, i.e. video and audio streaming applications.
Things might have improved for you due to other fixes which were committed to the xhci driver over the last few days, before isoch transfers got enabled.
