I get some of these messages every time I run this for a few hours:https://github.com/markfirmware/bluetooth-dev/releases
Code: Select all
[ERROR] USB: Device 3: SMSC95XX: Failed interrupt request (Status = USB_STATUS_HARDWARE_ERROR)
They might occur within the time frame of a dhcp refresh, but I am not sure.
They don't seem to have any negative effect on the intended operation of the kernel.
The interrupt endpoint is used for the link status detection which was added recently, like all interrupt endpoints it is polled (by resubmitting the request) multiple times per second and it is possible that the hardware will occasionally reject a packet.
The design allows for a failed interrupt request and simply logs the error and resubmits the request, we have noticed a similar thing happen very occasionally with certain mice and keyboards. We'll keep a note of this one to make sure it isn't a symptom of another issue.
