Bug description:
I am currently carrying out kernel testing and debugging with Alan Stern on the mainline kernel. Alan has proposed a patch to resolve a bug in USBFS that causes USB machine vision cameras to fail on kernels that contain the following patch:
commit e951f84074b84a3f5aecbffd01da74576e0068d5
Author: Lu Baolu <baolu.lu@xxxxxxxxxxxxxxx>
Date: Tue Jun 16 09:08:26 2015 +0800
usb: core: lpm: set lpm_capable for root hub device
commit 2d2a316765d956bc5cb6bb367b2ec52ca59ab8e9 upstream.
There is an issue in this patch that impacts software that rapidly
issues claim/release calls in USBFS, and all of our customers that use
Ubuntu 14.04.4 (kernel 4.2.x) and Ubuntu 16.04 (kernel 4.4.x) are
unable to communicate with their machine vision cameras using our
software stack.
The patch for the mainline kernel is being tested, and is currently posted, along with a history of this issue, at:
https://bugzilla.kernel.org/show_bug.cgi?id=115961
Right now, all of our customers have to either use an older kernel, or
manually patch their own kernel with the fix provided by Alan if they
are required to use a newer kernel. I am raising this bug so that,
once the patch is submitted to the the mainline/linus series, it can
be included in the next "monthly" kernel update made available to the
general public, and so our customers can just run a normal "vanilla"
system without having to rely on manually patching their kernel every
time they need to update.
