Hi ， I'm using the 4*A53 with DWC3 USB controller, my hardware to work
like a USB camera and so make use of the USB 3.0 UVC gadget driver。
usb3.0 isoc transfer with  missisoc -18，larger maxburst is set, the
more -18 appears。
but from trace info, the trb has been put in advance。

test setting:
dwc3 driver version：5.12
PC： potplayer

maxpacket : 3072
maxburst : 15
interval : 1
UVC_NUM_REQUESTS: 8

dmesg info：

What exactly is the problem you are having here?

What is not working how you expect it to?

You mean kernel version?

sorry, you're running 4.14.74 kernel. That's far too old for this forum
to help you. Try reproducing with the latest v5.13-rc kernel.

thanks for your reply.

my kernel is 4.14, but usb and uvc related driver has been update to
5.12.0 linux main line.
The problem mentioned above is after the update.

right, many other things happen in the framework. You could bisect and
try to find the offending commit, but this forum can't do much to help,
sorry.

That will not work, you have to update the whole kernel at once, drivers
can not be picked and choosen from different kernel trees and expect to
work at all, sorry.

Please try 5.12 or as Felipe said, the latest 5.13-rc release and let us
know if that works or not.

thanks,

previous 4.14 was problematic, so we updated it to 5.12.
after the update:
usb2.0 isoc\bulk\ all is well.
usb3.0 isoc with many -18 error...  bulk is normal
