The 16kB maximum for transfers was removed from the kernel in 3.3. Devio has since supported arbitrary transfer sizes through scatter gather. See the following kernel patches for context: "USB: change the memory limits in usbfs URB submission" "usbdevfs: Use scatter-gather lists for large bulk transfers" Bug: 67683483 Test: Run usb_async_test app with USB3 : 38MB/s -> 300MB/s Change-Id: Ia52440cb725561b0f1db1a75aa1b8ab952585826 |
