I am trying to run Kinect v2 on Ubuntu 14.04 (kernel 3.16)
When I run Protonect I got the -4 libusb error (LIBUSB_ERROR_NO_DEVICE).
The output of the program is

Protonect is using the patched version of libusb:

Any ideas to solve this problem?

Take a look to this issue #164. Maybe that helps for your problem as well.

I reduced the MAX_ISO_BUFFER_LENGTH to 49152, but it did not help. I tried also the solution of #174, but still does not work. It is frustrating because any time I use the Protonect program all the usb ports stop to work and I have to restart the PC.
In the meanwhile, I am trying the same thing on a Intel NUC and at least the RGB works, but the depth and ir windows are black. I noted that this is a common problem. As far as I understood, I have several options to solve this problem: upgrade OpenGL (the NUC has OpenGL 3.0), or compile with the CpuPacketPipeline (how can I do that?) or use OpenCL. What is the best option?

Since you have not mentioned it, I have to ask: have you checked the USB autosuspend settings? Ubuntu 14.04 has power saving config by default.

The OpenGL processor is basically using GPU but with overhead of abstraction several layers removed from the hardware. You should be able to do just fine with cmake .. -DENABLE_OPENGL:BOOL=OFF.

I have a JPEG decoding acceleration patch PR #210 for Intel. You might also want to try it out.

I tried the autosuspend as you suggest in #174, but it did not work.

On the NUC I tried with OpenCL and disabling the OpenGL and it works. I will try the JPEG decoding patch you suggest. Thank you!

I think this is a kernel level issue. As you can see

[  509.238571] xhci_hcd 0000:03:00.0: xHCI host not responding to stop endpoint command.
[  509.238580] xhci_hcd 0000:03:00.0: Assuming host is dying, halting host.

LIBUSB_ERROR_NO_DEVICE came from here.

It is frustrating because any time I use the Protonect program all the usb ports stop to work and I have to restart the PC.

This is something between the ASMedia USB3 controller and its kernel driver. I don't know what more can be done within libusb or here. You can still try different versions of kernel, from 3.12 to 4.0. Further than that, I guess you have to assume this ASMedia controller is not supported.

The same issue is me. I tried many combinations, e.g., disabling opencl, disabling opengl and none of them works.

@xlz to reset the usb port, you can use the following command (usb3.0 port only)

for i in $(ls /sys/bus/pci/drivers/xhci_hcd/|grep :)
 do echo $i >/sys/bus/pci/drivers/xhci_hcd/unbind
 echo $i >/sys/bus/pci/drivers/xhci_hcd/bind
done

I am getting the same LIBUSB_ERROR_NO_DEVICE error on Ubuntu 15.04 with kernel 3.19.0-21-generic.

dmesg starts to show following errors right after protonect is started. After a while,device gets disconnected and program stops. Even tough I am not sure about the duration, I think,approx. after a hour, device gets disconnected.

AFAICT this controller hasn't yet been tested, this seems to be a pretty new one. The only ones we can confirm as working are those listed in the README; for any other controller, it may or may not work. Trying a different USB controller (either on a different machine or on an add-on card) will help to narrow it down.

@xlz I have found the problem that my usb 3.0 controller in the mother board is Asmedia, which is obviously in non-compatible list of the Kinect 2.0. After switch to one suggested in the Kinect 2.0 support site, it works with no problem.

@rastaxe @zhangtemplar @bellekci

"ERROR Transfer event TRB DMA ptr not part of current TD" is the place the bug happens. What immediately follows is "HC is busted, give up!" and the rest is the fallout.

This may have something to do with the XHCI_SPURIOUS_SUCCESS quirk. What is the hci version from your dmesg | grep 'hci version'? If it's 0x96 or less, the XHCI_SPURIOUS_SUCCESS quirk is not added. If so you can try to boot the kernel (at least 3.14) with parameter xhci_hcd.quirks=0x10 to see if it is this issue. The result may be interesting.

@xlz sorry for late return, somehow slipped from my attention.

dmesg | grep 'hci version' returns unfortunately nothing. I am running 3.19.0.22-generic.
I have tested many kernels up to 4.2 but usb-freeze problem was still there. I will try to boot with xhci_hcd.quirks=0x10 now.

I booted with kernel 4.3 and no additional quirk parameter and this is what get for dmesg | grep 'hci version'

[ 0.625109] xhci_hcd 0000:00:14.0: hcc params 0x200077c1 hci version 0x100 quirks 0x00009810

Thus, XHCI_SPURIOUS_SUCCESS quirk is added and I do not know if I still have the no-device problem as it takes some time until device gets disconnected. I will let you know.

Yes, the problem is still there even with the XHCI_SPURIOUS_SUCCESS quirk.

Before disconnection, dmesg issues following warnings:

[ 378.038245] perf interrupt took too long (2524 > 2500), lowering kernel.perf_event_max_sample_rate to 50000

[ 479.772372] perf interrupt took too long (5070 > 5000), lowering kernel.perf_event_max_sample_rate to 25000

[ 996.839996] perf interrupt took too long (10123 > 10000), lowering kernel.perf_event_max_sample_rate to 12500

I also got this error:

[ 14.513302] [drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!

@bellekci Thanks for testing. I guess kernel's USB 3.0 maintenance has really gone down hill since Sarah Sharp.
