Thanks for the bug report, looking at the bug reports, they all
report an error of -71 which is
EPROTO, which typically means something is wrong at the USB level.
And nothing has changed for the driver in question between 3.1 and
3.2 , so I believe this regression
is caused by changes to the usb sub-system, likely changes to the
EHCI driver.
I have tested the new 3.12.0-rc1 kernel and the regression is still
present. It causes that Cheese crashes with a segmentation fault and I
get the following errors
