Hm, wait.  I mean use your sysfs patch, _and_ my patch.  Previously you
had said your sysfs patch had only moved the oops elsewhere.  I found
that true myself, hence my patch.  With both patches, things work for
me, how about you?

Oh, about all of that debugging output, just enable debugging in the
usbserial core, not the usb serial driver.  That makes it much more
managable :)
