This is a followup for this bug https://bugzilla.kernel.org/show_bug.cgi?id=103631 The problem still happens with kernel 5.2.0-rc4 and bluez-5.50-6.fc30.x86_64 When I unset CONFIG_HID_BATTERY_STRENGTH the problem no longer happens. But as a consequence, there's no information at all about the mouse's battery strength. So I'd say the original patch is suboptimal. https://bugzilla.kernel.org/attachment.cgi?id=203881&action=diff But still better than random disconnects all day long. Any suggestions on how to collect more information on the device for a better fix? Chris Murphy
