Hi !
So I'm toying a bit with the gadget subsystem, writing an UDC driver
for the Aspeed BMC SoC.
One thing this HW does (which I'm not yet enabling) is that it can
show as a virtual hub with up to 5 devices underneath.
The hub and each device has independent EP0's, and there's a pool
of 15 "gen

When plugging an USB webcam I see the following message:
[106385.615559] xhci_hcd :04:00.0: WARN Successful completion on short TX:
needs XHCI_TRUST_TX_LENGTH quirk?
[106390.583860] handle_tx_event: 913 callbacks suppressed
With this patch applied, I get no more printing of this message.

The kernel parameter pci=nomsi on boot fix everything.
Thank you very much to all.

Hello.
lspci -vvv show irq 11 for the device but cat/proc/interrupts show
interrupts 16 and 17 for xhci_hcd but my pc only has interrupts 0 to
15
Can that be the mistake?
cat /proc/interrupts
