I want to reactivate the USB device

Bonjour, Hi ,
J'ai un Macbook pro sur OS X 10.9.4, processeur 2,5 GHz, intel core 5. Mon port USB a été désactivé en me disant que l'appareil que j'avais connecté ( un I-phone) prenait trop d'énergie. Comment puis-je le réactiver?
How to reactivate the USB device?

USB is used by the display for brightness and other functions, in addition to being a hub. The USB circuitry is part of the main board, and is not upgradable. Connect a USB 2.0 hub to the computer if you need more USB 2.0 ports.

Hi there, can anyone tell me how to make make Garageband ignore HDMI as an audio output-device on a 2013 Mac Mini? Now it keeps on prompting me: Do you want want to use the HDMI device (monitor without audio) for audio output? Thanks in advance, Grtz T.

Hi there,
Can anyone tell me how to make make Garageband ignore HDMI as an audio output-device on a 2013 Mac mini i7 using an Apogee jam as an input for bass and a Behringer USB DAC with RCA audio output? Now it keeps on prompting me: Do you want want to use the HDMI device (monitor without audio) for audio output? I'm also suffering massive audio lag issues with the Apogee jam after waking the mini from sleepmode, wich pretty much renders it useless.
Thanks in advance,
Grtz T.

I think the easiest way to do this is to have the EyeTV app running in one user account and sent via HDMI to the TV, and use a separate user account for Screen Sharing. Both logins can be active at the same time and with Lion you can connect via screen sharing to which ever login you need.
With regards to the Mac video resolution changing, when it is not the current input on your AV receiver. This is 'normal', if the Mac sees no signal it drops down the a lower level. What you need is to buy a HDMI Detective Plus which tricks the Mac in to always seeing a signal and hence it will not drop down the resolution. See http://www.gefen.com/kvm/dproduct.jsp?prod_id=8005
The Mac mini does have an IR receiver. This can be used with the EyeTV app, iTunes, and similar. Yes I believe EyeTV would run for prolonged periods quite happily, it is has been around for a long time and had most of the rough edges polished off. However one issue you will have to deal with is that it does not automatically update its program guide data. For this you might have to write or modify an AppleScript. Elgato support or their user forums will be a lot of help.
You can set EyeTV to convert recordings to an iTunes (Apple TV) compatible format and then delete them from EyeTV.
The HDMI Detective should solve your handshaking problems.

HT4101 What does it mean when it says that the USB device requires too much power?

What does it mean when it says that the USB device requires too much power, when using the ipad lightening pin camera connection kit?

Just that. The iPad allocates a certain amount of power to that port. If the device you're trying to plug in wants more than the iPad is willing to give, it'll trigger that warning.
If it's something that you just must hook up you can try using a powered USB hub, but results are mixed at best.
What are you trying to hook to your iPad?

IPod Nano: Error Message "The USB device has malfunctioned and Windows does not recognise it"

Hi everyone, I just received 2 brand new iPod Nanos for my kids for Christmas, thought I'd be smart and sync them both now before wrapping them so I don't have to be messing around with them on the day. One synced without a problem, then using the same cable, same computer, same USB port, the 2nd one came up with "The USB device has malfunctioned and Windows does not recognise it" I've tried restarting my computer, unplugging and reinserting the USB. Is there anthing else I can try before returning it? Thanking you for any help.

I have solved my problem, I ended up ringing Apple and got an awesome lady who told me to reset it by pressing the sleep button and menu button together for about 10 seconds and once it actually turned on for the first time the computer then recognised it, so it's all good, :-) Thank you lovely lady!

The USB device Apple Internal Keyboard / Trackpad

Hello,
in the console of my rMBP 13 mid 2014 I have a lot of messages of this type:
The USB device Apple Internal Keyboard / Trackpad (Port 5 of Hub at 0x14000000) may have caused a wake by issuing a remote wakeup (1)
can please somebody give me some information what this message mean?
Thanks

There are 3 checks that can be performed initially:
- perform a NVRAM reset : About NVRAM and PRAM
- perform a SMC reset: Intel-based Macs: Resetting the System Management Controller (SMC)
- perform a Safe Boot : OS X: What is Safe Boot, Safe Mode?
- then reboot to normal
If the issue persists: run Diagnostics. Using Apple Diagnostics
and check if any codes come up : Apple Diagnostics: Reference codes

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Software needed for the USB device, "USB Interface Controller TEST2.0"

My mother recently acquired a digital camera. She acquired it from a second-hand store, which did not include an interface cable or software. The manual (and the USB port on the camera) indicates that a male-male USB cable is necessary for photos to be copied to the hard drive.
I was not successful in locating such a cable at any local electronics store (I assume such a cable is now out-of-date). I purchased one from a seller on eBay. The brand is "e circuit electronics".
Upon powering up the camera with the cable connected to it and the computer, the following message appeared:
"Software needed for the USB device "USB Interface Controller TEST2.0" is not available. Would you like to look for the software on the Internet?"
I clicked "Yes". After an approximate two-minute wait, another message appeared stating:
"Software Update is not able to connect to the Internet. Please check your configuration and try again."
I deleted, "Software Update Preferences" in the Preferences folder inside the System Folder, without solving the problem. How do I solve the issue of allowing Software Update to connect to the Internet?

Thank you for your continued assistance, BDAqua. Unfortunately, the driver you linked to does not seem to be compatible with the camera. It is a driver for the V20 model, whereas my model would correspond to be a V2755, as referenced from a list of other Vivicam models when during a search at the Open Drivers web site.
From the system requirement about the card reader you gave me, it will not work, as this system is running 9.1. I am hesistant to upgrade this computer to 9.2, as I have experienced system unstability with that version, with even the 9.2.2 update applied.
In the mean time, I have e-mailed Vivitar regarding this issue, but have as of yet received a reply.
I am not certain as to other specifics to give you, in order to solve the Software Update problem. Please elaborate.
Yes eww, the computer in question is able to fully connect to the Internet for all that I need. I am fully aware of the difference between a computer connecting to the Internet, and a computer connecting to a digital camera. I have 15 years of Macintosh experience.

Hi,
I have this printer HP Laser M1522nf.It was working fine till today.Suddenly it has started giveng this error
"HP Laser M1522NF the USB device attached to this computer is not recognised and has Malfunctioned"
This error is not on printer but on my computer when I connect the printer USB cable.I have 3 laptops all have winxp installed on them.I have tried connecting the printer with all laptops and they all give the same error with reference to connecting usb printer cable and Malfunctioning.
Appreciate your gracious advice and guidance in this regard,

Is this at an office and you are logged in not as an administrator?
If that's not the case, then the message maybe true, that it did malfunction, and need to be serviced. (assuming you already tried power cycle the printer, making sure doors/trays are all properly put in.

"USB Device Not Recognized. One of the USB devices has malfunctioned..."

I'm running Windows XP with external hard drive. When hard drive is connected, iPod will not sync and I get message stating "USB Device Not Recognized. One of the USB devices has malfunctioned..."
When disconnect the external drive, he iPod appears in My Computer. However, iTunes is on external drive; therefore music is not syncing onto iPod. I've attempted the 5 R's as well as searching for iPod in Device Mananger. When iPod is conncected, it is listed in Devce Manage as "Unknown Device."
I've changed drive letters on boh iPod and external drive and get the same message. Please help.

QRe: Zen MX Causes "USB Hardware has Malfunctioned" Msg from Windows XpyUhh, Yes.
I used to same cable to attach my Motorola Razr and the computer correctly found it and identified it as such.
I also tried another cable (brand new) same thing.
I went to recovery mode and did a "CLEAN UP" but no dice.
I also got my I.S. tech guy to look into it and on the USB page it say "UNKNOWN DEVICE"? when he tried to delete it it did not help, it just reappears as "UDVC"? Also in looking into it it seems to have no drivers.
He came to this site and tried to do somethinm through here but it did'nt work.
Now in listening to it last night it began to 'skip' or what I call 'HICCUP" terribly. Where a song starts and stops, during the middle of it. ? It's always done it a little but it has been getting more and more common and now? It's WAY worse about it.
It has never been dropped, or nishandled in any way. I bought the clear hard case to protect it. And only has about 300 songs on it. Never used for anything else. No vids no pics, nothing.

Try putting it into "Disk Mode" http://docs.info.apple.com/article.html?artnum=93651
Then with it in this mode connect it to the PC and try to run the latest iPod updater to do a restore and update software if you have the option. the latest iPod updater is 2006-03-23 and can be downloaded here http://www.apple.com/ipod/download/

My computer (PC) will not recognize my ipod touch anymore. When I plug it in, it says the USB device attached to this computer has malfunctioned and windows does not recognize it.
