From 04b8c8143d46453a443ac32bfcd76ec952605765 Mon Sep 17 00:00:00 2001 From: Daniel Drake Date: Thu, 21 May 2015 08:23:50 -0600 Subject: [PATCH] Bluetooth: btusb: fix Realtek suspend/resume Realtek btusb devices don't currently work after suspend/resume because the updated firmware is quietly lost - the USB hub doesn't notice any status change upon resume, but some kind of reset has definitely happened as the LMP subversion has reverted to its original value. Set the reset_resume flag to trigger probe and upload the new firmware again. Like the vendor code, I assume this is not needed when the device is selected as a wakeup source and hence will retain power during suspend. On the 2 products I have to hand, when trying this configuration the hardware seems unable to keep the device powered up during suspend. The USB hub then detects a status change on resume and does a reset, so we do not end up in broken state. Signed-off-by: Daniel Drake Signed-off-by: Marcel Holtmann --- Reading git-format-patch failed
