kernel 5.2.7 support for usb Apple Superdrive is broken

[David Walthour]

I am new to this mailing list, so please go easy on me if I'm breaking
etiquete.

Upgraded my Fedora 30 install from linux kernel 5.2.6 to 5.2.7 (and
5.2.8) and my apple usb superdrive stopped working. Booting up in 5.2.6
and it works again as expected, so it appears to be due to changes in
5.2.7.  

I am unsure of where to look to see if this is already reported and
being fixed. If not, I am willing to help out in fixing it as it seems
to be a reasonably small set of diffs between 5.2.6 and 5.2.7 that
could account for it, but I am new to patching linux, so I am unsure of
where to get started. Any help would be appreciated.

Thanks!

I would start with filing a bug in fedora's bugzilla as the developers
there can help you try to narrow things down better than we can if you
can't build your own kernel images.

And, what do you mean by "not working", are there kernel log messages?

thanks,
