bluetooth unavailable after 10.10.4 update (and possible workaround)

After 10.10.4 update on my iMac (Late 2013), Bluetooth status icon says "Bluetooth: Not Available". Apple wireless keyboard works fine, and the trackpad works like it's a mouse -- and gets its settings from the mouse settings. Bluetooth pref pane shows both are not paired, and I'm unable to turn bluetooth on.

SMC reset didn't help. Combo updater didn't help. NVRAM/PRAM reset didn't help.

Here's what the console is saying:

Given this, I unplugged a "working fine under 10.10.3" third-party USB WiFi device and its driver from /System/Library (RT2870USBWirelessDriver.kext), and reset SMC again. No luck. Then I unplugged *all* USB devices (scanner, hub etc) and Thunderbolt devices except the external monitor, and did another SMC reset. Bluetooth is back and trackpad is working as before. I haven't yet tracked down the cause, but it seems there's an interaction between USB and Bluetooth devices.

Similar problem on my iMac (Retina 5K, 27-inch, late 2015) and Magic Mouse after updating to 10.10.4:

The symptom is that my Apple Magic Mouse will move the cursor and make right and left clicks, but gestures with either one or two fingers either vertically or horizontally no longer do anything.

I tried restarting the iMac and the Mouse together, but it did nothing.

Bluetooth System prefs shows: "Apple Magic Mouse (Not Connected)."

Bluetooth menu bar item says, "Bluetooth: Not Available" (which seems odd to me, since the mouse has *some* functionality).

The Mouse System prefs only has settings for Tracking speed, Double-Click speed, and Primary mouse button.

System Report from About this Mac under Hardware/Bluetooth reports "No information found".

Thanks for your help in resolving this.

Ok, taking a page (ahem) from Bob Page's original post above, I unplugged all of my USB devices from the computer, then did a normal restart. I figured I'd try the simplest first. It worked, no need for me to reset the SMC.

Normal restart with all USB devices unplugged restored full Bluetooth functionality. All mouse gestures are back, the menu bar item is working again, Mouse System pref pane has all the native options for the Magic Mouse, and it's back in the System report under Hardware.

Glad it worked. Once my Bluetooth came back, I plugged in all my USB and Thunderbolt devices (except the USB wifi) and rebooted - system came back up normally.

After updating from 10.7.5 to 10.11.5, the Bluetooth would not connect to the Magic Mouse. Interestingly, the Bluetooth was "on" with no "off" option available either in the menu or the Bluetooth system preferences. Restarting in the Safe Mode restored functionality to the mouse and bluetooth. I restarted the computer and reset the SMC and parameter ram with no improvement. Bluetooth did not work.

Following the instructions above, I unplugged all the USB devices including the keyboard and external USB hard drive. I restarted the computer and there was not Bluetooth option in the system preferences and the Bluetooth menu indicated "Not Available".

I restarted the computer and full functionality of the Bluetooth was restored in the System Preferences as well as the Menu Icon. I had a "off" feature and the bluetooth was able to see and connect to the magic mouse.
