 |
|
Hi !
I have installed a Gentoo ( version 4.4.6 ) on a Zotac Magnus EN970 and use it to do some stuff with a Primesense Sensor.
The Zotac contains 2 x USB 3 in front face and 2 x USB 3 + 2 xUSB 2 in back face.
The Primesense is plugged on a USB 2 port.
When I used lspci -k I see 2 USB controllers (the first on xHCI for USB 3 and second on EHCI for USB 2)
| Code: |
00:14.0 USB controller: Intel Corporation Wildcat Point-LP USB xHCI Controller (rev 03)
Subsystem: ZOTAC International (MCO) Ltd. Wildcat Point-LP USB xHCI Controller
00:1d.0 USB controller: Intel Corporation Wildcat Point-LP USB EHCI Controller (rev 03)
Subsystem: ZOTAC International (MCO) Ltd. Wildcat Point-LP USB EHCI Controller

When I list my USB devices everytimes I plug any devices on a USB 2 port I see that he it used by the xHCI USB Controller :

I really do not understand if I have kernel configuration issue or if its a hardware issue..

In Fact it's not a big problem because I can still used the primesense, but sometimes the Primesense do strange stuff, so I need to reset the USB port.
To do this, I play with /sys/bus/pci/drivers/xhci_hcd/(bind/unbind) and frequently when I do this, my USB controller can't initialize the Primesense :
dmesg

And when I have this message I have to unplug and plug the Primesense manually to restart it.
I think that is an xHCI issue because with an other computer which attached the Primesense correctly on the eHCI controller I have no error when I play with /sys/bus/pci/drivers/ehci_hcd/(bind/unbind).
I really hope that I have clearly explain my issue, and thanks in advance for any answers/explications. |
