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
