4.18-stable review patch. If anyone has any objections, please let me know. ------------------ From: Maxence Duprès <xpros64@xxxxxxxxxx> commit 9b83a1c301ad6d24988a128c69b42cbaaf537d82 upstream. 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.
