This is a note to let you know that I've just added the patch titled

USB: add quirk for WORLDE Controller KS49 or Prodipe MIDI 49C USB

to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

If you have any questions about this process, please let me know.

WORLDE Controller KS49 or Prodipe MIDI 49C USB controller cause a -EPROTO error, a communication restart and loop again.

This issue has already been fixed for KS25. https://lore.kernel.org/patchwork/patch/753077/

I just add device 201 for KS49 in quirks.c to get it works.
