I had a look at what JMicron's driver does differently from the version included with Linux. It appears that it periodically checks for link failure and then automatically applies this workaround. I could try cleaning up the automatic workaround a bit and submitting upstream, but I doubt that it would be accepted. In short, this is faulty hardware and you know how to work around it. I think there nothing left to be done. > 'Upgrading' my laptop to Jessie felt like a definite downgrade as it > prevented me from using my computer. So I'd call this bug SERIOUS. Sorry but I do not agree. Ben. -- Ben Hutchings Once a job is fouled up, anything done to improve it makes it worse.
