Hi Xenia,
I tried these 3 patches and ... I will rather leave it up to you to decide
if everything went right. Attached is a diff of dmesg from unpatched and patched
3.10.9 kernel. USB3 devices were connected before cold bootup, sadly in latter test
the ordering changed a bit so that added to the length of the diff. Can't say
what those Prolific-related messages mean. Just in case you need more info
I attach "lsub -v" as well.
