OSX 10.11.3 and USB PROBLEMS

[Eduardot]

Since upgrading to El Capitan, I started having problems with my USB Bose speakers, disconnecting randomly. Hoping the issue would be dealt with I continued upgrading to the current version 10.11.3, and now I have a malfunctioning USB monitoring Video Camera.
When Are these USB problems going to get handled appropriately?

Now i cannot listen to music and also have video problems, cannot monitor through a video camera conected via usb to my iMac. I have read of sound problems, printer problems, music decoding, video, all tied to the usb bus. So what's next?

I'm on 10.11.2 and my three DAC (Tascam, MOTU UltraLite and AudioEngine D1) work perfectly through a hub on the USB 3 bus. My external HD work perfectly as long as connected directly to my Mini i7's USB ports. If connected to a hub they suffer random dropouts.

Thanks for the heads up. I'll stick with 10.11.2 and avoid 10.11.3!

Amazing, what brought me into Apple the user friendly interface, and the ease of communications between all Apple hardware, may just be what will bring me out of Apple. Still not able to listen to my music and to handle all my usb hardware due to some brilliant reprogramming of the USB ports. I am seriously considering going back to windows. That would necessarily carry all, Desktop, laptop, tablet and phone also. Apple fix this or you risk a lot of people abandoning the " user friendliness ". There is still time. Make it SO!

Maybe it's time to go to Windows if Apple persist with these problems. It's sad how Apple doesn't fix problems like this.

What is the difference between USA and USB ??

One connects to all your devices and accesses your data

The other is a hardware standard.

Does the hardware you use require custom USB drivers? I haven't got a single report of any issues of USB malfunction so far, and we use a lot of USB recording equipment.

Well, Windows isn't exactly free of USB compatibility issues and general flakiness. I hear the screams of woe daily from my Windows using friends in the office next door.

I'm still using 10.11.2 and and my three DAC and drives work perfectly as long as I don't plug the drives into a hub. One thing that changed when I went from 10.9.5 to 10.11x is my Mac no longer automatically switches to a DAC I just powered up. I actually have to go to the sound panel in system preferences and manually select input and output devices or it defaults to my Cinema Display sound. Also have to do the same in Adobe Premiere, Bias Peak and iTunes. Maybe the OP needs to select his output device at both system and app levels?

The Speakers are Bose Companion 5, Bose says no updates in drivers. I had them connected to a hub in Yosemite and worked perfectly. Now in El capitan even if I connect them directly to the iMac, the problems persists.
I have a monitoring usb camera with EyeTv software through the hub also that initially was ok but now is freezing the video feed randomly.

My wife has those speakers. She is on 10.10.5, not 10.11.X. She has ALWAYS had issues with the Bose disconnecting and the speakers in the LED Apple 27" monitor taking over... until I replaced the monitor and plugged the Bose directly into her computer. Since then she has had no issues.

I have always had a problem with USB hubs. Devices will keep "refreshing" (for lack of better words). For example an iPhone will charge to 100% then disconnect, the "bzzt bzzt" as it reconnects, charge, disconnect, etc etc. Or a external disc drive light will keep flashing as if I was plugging it in and unplugging it over and over.

In use the devices will work fine however the behavior they exhibit when not in use isn't correct and incredibly annoying...to the point that I can't use a USB hub.

I've tried powered and non powered hubs. Fresh installs of El Capitan, various cords, devices etc.

Same hubs work perfectly fine on a friends Windows 10 machine which is frustrating because he has access to 8 USB ports "built in" meanwhile with an iMac I have to rely on a hub that I can't get to function properly.

Maybe if anyone has run into this they can chime in.

 

[Gochugogi]

I've only found two hubs that work well with my Mini under 10.11: the hub built into my Cinema Display and an Inateck combo USB 3.0 Hub and Hard Drive Disk Enclosure. Everything else randomly dropped the connection. I have five useless USB 3 hubs from cheap to expensive collecting dust.

I'm considering adding another external SSD partially so I can buy another Inateck combo...

Not sure if my issue is connected to the OP but I've now got dropouts and stutters when outputting audio on any app through my Roland Quad capture on my late 2013 i7 iMac. Also occasional pops and clicks when recording in Logic. All started since 10.11.3. I've had to reinstall a 10.11 on a partition temporarily where everything sounds fine.

The usb frezzing my camera feed and my bose speakers persists. What are we to do Apple?. Somehow I cannot see me going back to windows. Help Apple......... HELP.........!!!!!!!!!

 

[xgman]

They have been messing around with something to do with the USB bus from the 10.11.2 betas onward, although most of the issues seem to be clipped back once the .2 and .3 release hit, but it was clear at various points of the beta testing that they were up to something. Just not sure what...

Apple implemented new, aggressive power management in OS X 10.11+:

From:
https://www.apple.com/osx/all-features/pdf/osx_elcapitan_core_technologies_overview.pdf

USB Power Management Traditionally, USB device power management is done manually, with a function driver making explicit suspend or resume calls on a USB device service. This is error-prone and results in overly complex driver code to manage power state. USB in OS X El Capitan has been completely implemented to benefit from the same USB architecture and aggressive power management policy adopted by iOS. Each endpoint in a device can be given an idle timeout in milliseconds, and an endpoint is considered idle if an active transfer hasn’t completed within that timeout. The device has an idle state as well, which is a logical AND of the idle state for the endpoints associated with the device. Only when the device idle timeout expires does the OS pause I/O on the bus and electrically suspend the device at the port. The idling system is an important advance because drivers don’t need to actively participate in power state transitions.

The firmware of older devices is probably incompatible with this new power management. I have no USB problems with newer USB 3.0 or USB 2.0 devices.

Then Mr. Retrofire, could you recommend usb speakers as good as Bose and a video handling solution as good as El Gato so my problems can be solved?

This is absolutely the root of current OSX USB compatibility problems.

I think Apple will not be putting this back the way it was, so it is going to be up to the peripheral manufacturers to update or fix their devices.

@Eduardot:
You can try this in a Terminal window:

sudo pmset -a autopoweroff 0
