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

No, I originally wanted to understand the differences of the firmware
loading mechanism as I assumed a patch migrating away from the unified
firmware interface would not be accepted anyway.

Unfortunately, I never found time to do this.

Thanks for bringing this up again.

Given I have two different affected devices, I am more than happy to
test any new versions of this patch.

Cheers,
