Subject: patch "usb: xhci: ASMedia ASM1042A chipset need shorts TX quirk" added to usb-linus
Date: Mon, 12 Jun 2017 16:05:36 +0200 [thread overview]
Message-ID: <149727633612830@kroah.com> (raw)
This is a note to let you know that I've just added the patch titled
usb: xhci: ASMedia ASM1042A chipset need shorts TX quirk
to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Subject: usb: xhci: ASMedia ASM1042A chipset need shorts TX quirk
When plugging an USB webcam I see the following message:
[106385.615559] xhci_hcd 0000:04:00.0: 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.
