Hello,
I have a PCIe card with ASM2142 USB Host Controllers on them. I have
attached a SuperSpeed UVC camera to it. This camera works on other host
controllers, but with the ASM2142 the transfer stops after a frame or
so. Dmesg shows me the following error:
> Transfer event TRB DMA ptr not part of current TD ep_index 6 comp_code 13
I have tried different XHCI quirks but did not have success with any.
The full log with xhci_hcd debugging enabled is as follows:

Do you have any idea what might cause this, or any suggestions how I can
debug this further?
Thank you in advance!

Hello,
I tried to debug this a bit.
It seems that the XHCI ring has two segments. For me, the first has DMA
address 0x00000000fffb9000 and the second has 00000000fffb8000.
The TRBs on the first segment are used successfully up to address
00000000fffb9fd0 (which seems to be 253 TRBs?).
After that, the DMA address in "handle_tx_event" in "xhci-ring.c" points
to the first TRB in the second segment, but "deq_seg" of the ring still
points to the first segment. This obviously will cause the error I see.
Now the real question is why it still points to the old segment. I guess
this should be handeled by a link TRB? Then it seems that it is either
missing or handeled wrongly?
I'm still a bit confused about if this is a host controller or driver
problem.
Thank you in advance and best regards,
Ole

Hello,
ok, skimming over the xhci spec helped me to understand a bit more.
The problem is the following:
The xhci driver enqueues TRBs for transfers on the transfer ring. When
it comes to the end of the segment, the cycle bit of the link TRB at the
end of the segment is toggled in "prepare_ring" and we continue to
enqueue TRBs on the next segment. So far, so good.
The controller reads the TRBs and processes them. But I assume that this
happens asyncronously. The driver receives the corresponding events on
the event ring from the host controller a bit later.
But once the cycle bit of the link TRB is toggled the host controller
just reports the address of the first TRB in the next segment on the
event ring. It forgets about all outstanding TRBs on the first ring
before the link TRB.
I assume that this is a HC firmware bug. I can successfully work around
it by toggeling the cycle bit of the link TRB not in "prepare_ring" but
in "handle_tx_event" after receiving the event for the TRB right before
the link TRB.
I'm not sure if that is the best way to work around the problem though.
Do you have any ideas how to best fix this?
Best regards,
Ole
