Confirmed. I sent the same patch (without the comments) to linux-kernel
three days ago.

BTW, perhaps it would be better to patch the thing the following way,

1000 and 9009, perhaps there are other devices which don't like the
workaround?

Interesting, twice the same patch, and then from nearly the same location
in the world. (Roermonder Str. 112a - distance several 100m )
