This is a note to let you know that I've just added the patch titled
usb: quirks: add NO_LPM quirk for Logitech Screen Share
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.

LPM on the device appears to cause xHCI host controllers to claim that there isn't enough bandwidth to support additional devices.
