Provide USB port power during Macbook Pro Sleep mode

My old Macbook used to go to sleep, with lid closed, and charge my phone via USB cable.
With my i7 2010 15" Macbook pro however, I cannot see how to configure this same feature. Basically when the lid closes, the unit goes to sleep, including the USB ports.
In order to charge my phone, I am forced to leave the computer on.
This seems like a giant step backward for a traveler like myself, one of the main reasons I made the investment in the new Macbook Pro was for the great new battery life.

I have the same problem. This was working, but it seems that after the last security update all USB ports are turned off completely, so my iPhone and iPad (both of which I leave connected to the USB ports) do not get charged. This is a big deal with my iPhone.
Is there a configuration parameter on my MBP I should check?
Thanks!

My USB port on my Macbook Pro stopped working and i tried the SMC reset and the one closest to the SD port still continues to not work. Is there anything i can do besides bringing it in?

I would do another SMC reset. If nothing changes you should take the computer in to an Apple store for a free diagnostic. You should make an appointment.

Why can I no longer use my exterior speakers connected to the USB port on my MacBook pro

QuestionWhy can I no longer use my exterior speakers connected to the USB port on my MacBook pro ?

Have you checked the Sound Preferences under the System Preferences and set it to USB speaker for the sound output? Sometimes it can change on its own or after and update of an App or the OS?

USB ports in my macbook pro stop working

For a few months now the USB ports in my Macbook Pro stop working. The mouse is unable to move the pointer, therefore, I have to use the trackpad to select things. Then, when i try to shut it down it refuses to shut down, so I have to hold the on/off button to turn it off. When I turn on the laptop, the problem goes away. It's been happening more often for the last few weeks. Is there a problem with the software or is it the fact that I never used a base to raise the laptop, until recently, to let air in below so it doesnt heat up so much?
Any help is appreciated.

HT202731 Unstable operation when 2 or more USB devices connected to usb port on a MacBook Pro running Yosemite

I have tried connecting a number of devices to my MacBook Pro but I have found if I try to connect 2 or more using either usb ports or a usb hub the computer reports 'disk not ejected properly' and sometimes it will fail to recognise the device and remove it from the desktop or it stalls operation and I have to turn the computer off at the power button.
I have tried erasing the hard drive and reinstalling the operating system.
I have done various types of reset suggested by apple support.
The computer has been to an Apple dealer who has tested the hardware but found nothing due to the intermittent nature of the problem.
I have operated the computer with only the software originally installed on it present.
Could it be possible that a virus could be present on the usb devices I am trying to connect?
My computer is a MacBook Pro (13-inch, Mid 2012)
Processor 2.5 GHz Intel Core i5
Memory 4 GB 1600 MHz DDR3
Startup Disk Macintosh HD
Graphics Intel HD Graphics 4000 1024 MB
Operating System X Yosemite 10.10.1
Devices I have connected to USB ports all USB 3.0 compatible in a variety of combinations:-
7 port superspeed USB 3.0 hub (powered).
4 port Inateck USB 3.0 portable hub (not powered).
Buffalo ultra portable 500Gb USB 3.0 hard drive.
Seagate Expansion portable 500Gb USB 3.0 hard drive.
Seagate Expansion desktop 2Tb USB 3.0 hard drive (powered).
Seagate Expansion desktop 3Tb USB 3.0 hard drive (powered).
ScanDisk Cruiser Edge 16Gb USB stick.
ScanDisk Cruiser Edge 32Gb USB stick.
Hewlett Packard 16Gb USB stick. (This causes an instant crash now.)

Why?
- Because when I'm editing/ rendering lots of HD video everyday, I don't want to share system resources between virtual machines... I want the entire system's resources devoted to what I'm doing.
- I don't want to spend anymore money than I have to in order to buy one of the faster virtual systems. Not to mention, I've had a bad experience with Parralels in the past and I'd rather not use one again.
- I really don't want to clutter up my system anymore than I have to for a project that's only going to take a few weeks.
- I don't mind swapping hard drives... it takes two minutes, and I have an empty ssd just sitting on the shelf.
So, back to my original question. Can I just swap the computer's drives, then install Ubuntu on the second drive and be good to go without any harm to my MacBook Pro or OSX on the other drive (which wouldn't be connected when Ubuntu is running)?
Thanks.

USB Ports on my MacBook Pro are not working

My MacBook Pro (Original) USB ports recently stopped working. They come up in system profiler as being there, but when I connect a device, such as a flash drive, no leds turn on, and no power is given to it. I have tried resetting the SMC and PRAM, but all to no avail. Does anyone have any suggestions? Thank you in advance for your help

I had a nearly identical issue today with a new CTO MacBook Pro...specifically, the USB ports on this new unit were unresponsive to devices being plugged to their slots. We reset SMC to no avail, unplugged all other non-essential peripherals, and still no change.
We were specifically trying to boot a previously functioning Seagate hard drive with a fully intact install of Snow Leopard. Eventually the MBP detected the drive and read the contents. We selected the externally connected drive for startup (which S/L found without issue) in System Prefs. At boot, no progress further than Apple logo (without animated gears indicating some type of load process).
Moved to an identically equipped secondary Thunderbolt MBP which presented with exact same issue. To further verify this was an issue with the USB ports on a Thunderbolt model MBP, we attempted boot of the externally connected drive to an iMac and then a MacMini. Both of these units booted the drive without issue. The Thunderbolt MBPs can see the drive, read the contents, but can't boot them.
Disk Utility verified and ran repair on the external drive and reported zero problems.
Both MBPs are being returned to Apple. Too much to risk for only having two USB ports.

One of the USB ports on my Macbook Pro isn't working. Any way I can fix this or will I have to take it into the store to get repaired?

I bought a Macbook pro this July. Everything has been normal except about a week ago I started noticing I had to plug things in a few times in order for them to connect. Today I realized that one of my USB ports has been the problem, not my devices. THey connect right away when plugged into the right USB port next to the SD slot, but not at all when plugged into the left slot by the firewire hookup. Is this a problem that has a quick fix or am I going to have to go to the mac store?

Reset the SMC and PRAM
SMC Reset:
Shut down the MacBook Pro.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
PRAM:
Shut down the MacBook Pro.
Locate the following keys on the keyboard: Command, Option, P, and R.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

USB Ports don't work after sleep mode on Windows 7 Pro 64 bit

I have been using my laptop for about a month without a problem, but over the last week or two I have had a problem where I lose access to all of my USB ports when resuming from sleep mode. If I go into hybernate or restart the computer, the ports
miraculously return. The techs at the manufacturer can't figure it out and wanted me to do a full system restore, which is a little too drastic a solution! The only real thing I can connect it to, is I had to use Virtual PC (XP) around the time this
started.

Hi Greg,
Microsoft has been fixed this problem, but it is not successful with all PC/Notebook manufacturers. So, the OEM developers itself started giving patch for this issue. I have seen the patch upto Windows Vista version. Lenovo, HP, Dell and other people
are providing this patch. Sony is providing this patch for some selective models. Go to sony support, enter or auto detect your model and check for the update. With Windows 7 SP1 your USB drives should work properly.
Anyway, check the below sony support link to understand how to wake up a USB drive after sleep in Vista, Do the equivalent modification in your Windows 7 PC registry. It will work for you.

Hope this will work for you.

Has anyone ever had a USB port on their Macbook Pro suddenly go dead?

I was just wondering whether anyone using a MAcbook Pro Retina has suddenly had one of their USB ports die on them? My one port does not seem to recongise any peripheral hardware I attach to the port and I am confused why this should have happened. Apart from the obvious reason which is probably that the USB port has died I was just wondering whether this is a common fault with these machines and if it is, whether someone else may have a few words of wisdom related to how to solve the problem. The machine is not even 6 months old so I am reluctant to simply write this off to a failed USB port which will be the first time this has ever happened to me. I would value any input.

Hi C,
You have a one year warranty and I would definitely bring this to Apple for diagnosis and repair.

One of my usb port in my macbook pro is not working.

Is there anyway i could fix this?

I have a belkin 7 adapter for additional USB slots for my Mac Pro. It was working well till just recently I am getting a message that says the usb port on the Mac Pro is shutting down due to a very high power drain. Then it shuts the usb port down.

I have a belkin 7 adapter for additional usb ports for my mac pro. It worked fine without problems till recently when the message regarding usb port drawing too much power and the computer shuts the port on the mac pro down. The strip comes with its own power supply adapter. The attachments are additional hard drives used as backups and independent data. Other than disconnecting it are there any fixes?

You're getting the message because you're exceeding the available current, probably as a result of bus-powered drives. The power sources for hubs are rather small. Try using drives with their own power supplies.

I plugged a usb in to my macbook pro and rhe computer went off and wont turn back on. the power light doesnt light. what do i do??? help!

Do you have Apple Care? Is there an Apple Store near you?
Sounds like a hardware fault...

USB problems on my Macbook Pro 15"

Hello all,
I just purchased a macbook pro 15" with an i5 processor (2.4 GHz, 4.0 GB RAM) a week ago and im trying to transfer my stuff from windows computer to this macbook.
I have 2 usbs, one is jus a regular SONY VAIO 32 GB USB 2.0 and the other one is an external hard drive that i got from my old computer - 160 GB. THe usb obviously plugs directly and the external HDD requires AC power and a usb cable.
Anways, Wen i try to connect this and start transferring files to my SONY usb, it starts and then it disconnects itself in between everytime. I use it on my windows pc and it works perfectly fine. I also safely remove the drive and not just pull it but still my macbook gives me warning saying "The disk was not ejected properly. If possible, always eject a disk before unplugging it or turning it off."
Also, wen I use my external drive, it doesnt even open and it gives me warning saying the usb drive is using too much power and ur port will be disabled until u unplug it.
I was just wondering how to deal with this problem. Is it with my USB ports on my macbook? or is it just the usb cables? it works perfectly fine on windows. And yes i've tried using both my macbook ports.
Please help
Thanks a lot
have a nice day!

I have a similar problem (MBP 15" hi-res, i7 2.8GHz). Apparently this is a timing problem, a particular USB stick (which was used a lot) fails to mount, while an exact identical second stick (less used) mounts. Both sticks mount on my late-2008 Core2 Duo MBP. Also, reading from my digital camera on the i7 MBP reports errors, while it reads correctly on the Core2 Duo MBP (both running 10.6.5).
Analyzing the log files reveal timeouts on the i7 MBP. In my opinion, the USB driver has a problem handling the USB protocol on the new, faster processors. Unfortunately I upgraded the i7 MBP immediately to 10.6.5, so I don't know if the problem is related to 10.6.5.
However, to my observation, the failure is clearly related to the USB device speed: My Toshiba USB disk works fine (fast), the less used USB stick works fine (still fast), the heavy used USB stick fails (slower due to flash reorganization), the camera fails (known slow).
Maybe someone with deeper insight into MacOS can provide a hint how to adjust the USB protocol timing.
Kind regards,
Manfred

USB ports power management settings

An All-In-One HP Printer, Scanner, Copier is connected via USB cable, directly to one of the two USB ports in the Macbook. When the Macbook is put in sleep mode, the connection between the HP and the Macbook is interruped (I presume) because in sleep mode, the power (from the computer) to the USB ports is turned OFF, instead of being kept alive, or even reduced. Upon waking up, the HP's functions are partially disabled, e.g. there is no possibility of scanning a document. Restoring all the functions requires uninstalling the HP software, when some of its components have to be trashed manually, and reinstall the software. HP technical support has been very responsive both in contents and in speed, but suggest that the problem might be caused by the power being turned OFF to the USB ports, when the Macbook goes into sleep mode. They suggest either to power OFF the AIO HP before putting the Macbook to sleep, and powering ON the AIO after the Macbook wakes up and regains complete functionality. They also suggest to change the settings of Power Management to the USB ports. I have searched the forums here, and the web in general, but have found no indication that it is possible to change or even access the settings of the power that feeds the USB ports of the Macbook. After this long introduction, for which I apologize, here come two questions. 1) Is there a way, maybe via Terminal, to change the USB power management settings, and how? 2) If there is no such way, would it be possible to work around the problem by connecting the AIO, via USB cable, to a powered USB hub (connected to the Macbook), instead of connecting it directly to the Macbook's USB port, the "rationale" being that the USB hub is always powered, and stays powered when the Macbook is put in sleeping mode. Thanks in advance.

I have solved the issue by turning OFF the printer before sleeping or turning off the computer itself.
