I have an USB3 device which I'm using through libusb (so usbfs) pulling
relatively large amounts of isochronous data (uncompressed 720p60 video,
so a bit under a gigabit per second) down to my X240 laptop. I submit four
isochronous requests of about ~2MB each, which seems to be enough to keep
10 matches
