From d012ab210f5f4ff4e6f5567fe80e1dcc82077c2d Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Tue, 3 Oct 2017 11:16:43 +0300 Subject: [PATCH] usb: quirks: add quirk for WORLDE MINI MIDI keyboard MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit commit 2811501e6d8f5747d08f8e25b9ecf472d0dc4c7d upstream. This keyboard doesn't implement Get String descriptors properly even though string indexes are valid. What happens is that when requesting for the String descriptor, the device disconnects and reconnects. Without this quirk, this loop will continue forever.
