I’ve just finished adding support for a USB3 Genicam camera using Aravis for control and capture, and have run into some lovely kernel warnings. Capture from the camera seems fine, at each of 640x480, 720p and 1080p, all running at 30fps, although every now and then I seem to lose a frame or two.
The kernel warning is as follows
tegra-xusb 3530000.xhci: WARN Event TRB for slot 1 ep 2 with no TDs queued?
I have increased the usbfs_memory_mb and disabled autosuspend, as per some other threads I found here, both to seemingly no effect. I’m not really certain whether this warning is indicating that something is going wildly wrong, or whether I can safely ignore it (I would guess not).
