Comment # 15 on bug 1092839 from Simon Lees

This is really a duplicate of https://bugzilla.suse.com/show_bug.cgi?id=1093378
i'm not sure if just fixing it for ftdi chips is enough there maybe other
devices that also have the issue, I have one or two here that have had issues
with tumbleed in the past but I don't remember if they were ftdi based, i'll
try and dig them out tomorrow and test.
