Hi list, I originally posted this on libusb-devel [1], but got a friendly redirect here by Alan Stern, hope this is the right place! Let me describe my problem from a "user" standpoint before diving into the technical details: USB 3.0 does not work on my PC flat out. Sometimes USB 3.0 ports work

ERROR Transfer event for disabled endpoint or incorrect stream ring

While copying a disk with the dd command from inside a live-CD-boot-system the following single error has been printed: xhci_hcd ERROR Transfer event for disabled endpoint or incorrect stream ring @000212409100 0a00 02088001 Does anybody know what these numbers mean?

[PATCH 1/4] usb: gadget: f_midi: refactor state machine

This refactor results in a cleaner state machine code and as a result fixed a bug when packaging a MIDI-USB packet right after a non-conformant MIDI byte stream. Signed-off-by: Felipe F. Tonello --- drivers/usb/gadget/function/f_midi.c | 204

[PATCH 2/4] usb: gadget: f_midi: added spinlock on transmit function

Since f_midi_transmit is called by both ALSA and USB frameworks, it can potentially cause a race condition between both calls. This is bad because the way f_midi_transmit is implemented can't handle concurrent calls. This is due to the fact that the usb request fifo looks for the next element and

[PATCH 0/4] More improvements on MIDI gadget function

Patch 1: The main improvement is the refactor of the state machine MIDI parser. It is better to read and handles states properly, even weird ones. Patch 3: Fix a race condition. Patches 3-4: Miscelaneous fixes. Felipe F. Tonello (4): usb: gadget: f_midi: refactor state machine usb:
