XHCI host dies with LPM + webcam gadget

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello Mathias,

I'm trying to connect a webcam gadget on USB3.0 interface with xHCI host when LPM is enabled. My xHCI host is TI's TUSB7340EVM. xHCI host stops responding as soon as the webcam gadget module is inserted on the device side (The device is also running linux)

Host machine kernel version is 3.16. I have enabled quirk for LPM enable for my XHCI card.

The detailed description and a host kernel logs can be found from bugzila:
https://bugzilla.kernel.org/show_bug.cgi?id=85141

Could you please help in rectifying this bug? Please let me know if there's any more information required.

Thanks
Amit Virdi
