Jakob, were you able to forward the patch upstream? I'm including
Johan and linux-usb list in this reply now.

Johan, fo context, it is about an older bug reported in Debian as
https://bugs.debian.org/833035 with users of the Keyspan USB serial
adapter USA-49WLC faling to load firmware.

There was a patch used, in
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=833035#68 tough
which hs no commit message or Signed-off-by's . Original patch is from
Ben in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=833035#24 .

Regards,
Salvatore
