When I plug in an USB stick, my MacBook Air disables all USB devices
When I plug in an USB device, my MacBook Air disables all USB devices and the keyboard. It looks like it would freeze, but all applications still work. It just does not respond to neither keyboard nor mouse. The only solution is to force-restart it. What can I do? I am using Lion and have updated it. The same error occured with Snow Leopard as well. Unfortunately, it sometimes happens and sometimes not. I have a suspicion it is related to the devices power consumption in corelation with the battery charging status.
I am using a MacBook Air 13", late 2010 version.
Have you tried plugging the flash drive into a different Mac to see if it works? The Air shouldn't have any problem with it, I use a couple of flash drives in mine, although I don't have a pq1. Did you try both USB ports on the Air? Do you have another flash drive you can test in the Air, or a different USB device, like a hard drive or printer?
The only thing I can think of is either a bad flash drive, or a bad USB port on the Air. Sorry, can't be more help than that.

Hi
When I plug in my iphone to my macbook air it says the computer is not granted to take the iphone information. So I haven t been able to import the iphone information (like photos) to my laptop.
This is the first time it happened to me, because last week I could done that.
Could anyone help me please fixing this issue?
Thanks.Try unplugging any other USB devices. If you are using a hub, don't, connect the phone directly to a computer USB port.
None of these are necessarily things you should do, but might help. For instance, if you plug the phone to an already busy hub, the phone might be "the straw that broke the camel's back" and lock out the hub. -
I want to connect my iPhone to my macbook to backup all my photos but it just vibrates constantly and flashes the trust computer question over and over.
Any help would be great.Talked to AppleCare and it's most likely the fact that my MacBook has 3.0 USB ports and my non official charging cable can't support that. So yeah, I'll try a new cable, hopefully that's the fix.

My 6th generation nano isn't recognized by my computer. When I plug it in an error message pops up, which says "USB Device Not Recognized". Does anyone know how to start trouble shooting this? I updated both windows and iTunes.
Work through all the suggestions in this Apple support document first.
iPod: Does not appear in Windows or iTunes and Device Manager is empty

Hi,
I am currently replying to this as it shows in the iChat Community.
I have asked the Hosts to move it to Snow Leopard (you should not lose contact with it through any email links you get)
I also don't do Wirelss printing so I can't actaully help either.

I have a new pc windows 7 and when i plug in my ipod it says it must erase all the data to sync. How do i get the music from my ipod to my new computer. The old computer is trashed and files are not available, songs are only on ipod.
One of the reasons why including your iTunes library with your computer's backup is a good idea. Use this link for future reference in this regard.
http://support.apple.com/kb/HT1751
iTunes includes an option to transfer iTunes content that was purchased/downloaded from the iTunes store from an iPod, iPad, and iPhone, but this is for iTunes content that was purchased/downloaded from the iTunes store only.
First you need to authorize your new computer with your iTunes account with iTunes if you haven't already done so.
With your iPhone connected and without syncing, at the iTunes menu bar go to File and select Transfer Purchases From - the name of your iPhone. -

Hi,I'm new here and I think my problem were discussed few times before.However,I tried to follow the solutions similiar to my condition but it does not work.My problem is whenever I plugged in the HP printer (Laserjet M1132 MFP) usb to my Macbook Air,a screen will pop-out and read as 'the disk inserted is not readable by this computer'.I even bought my Mac to the Mac store but the situation remains the same.Okay with other printer but not with my HP.Sigh.The HP printer worked just fine with other computers (not Mac).I'm really sick of it.Please help me.I once plugged in an external hard drive & started Time Machine with it.The printer problem started after that.However, the hard drive plug-in works just fine.
Your attention of above matter is highly appreciated.Thank you.Here is what worked for me:
I reset the System Management Controller on my MBA. To do so requires shutting it down, keeping it plugged in to power (I also unplugged both USB connections), and then from a powered off state I simultaneously pressed Shift + Ctl + Option + Power (I did this once and it did not work so I tried again and did it 3 times just to be safe), then released them at once, then I pressed the power button. Problem solved.

I also tried uninstalling the using the repair Disk Permissions with Disk Utility and moved the HP Printer software accessories to the trash (you can search the web for how to do that but that did not solve the problem either). Neither of these options worked. -
I just bought a Macbook Air and a usb super dive. How do I install MS Office 2003 on it? It won't launch the install when I load the disk in the superdrive.
A 2003 MS office sounds like a Windows version. A 2004 MS Office that was Mac compatible can not be run natively on a new MBA since the Lions do not run PPC applications. You will have to get a newer edition of MS Office that is compatible with your new MBA.

when i plug in my iphone to my macbook it says i need to update itunes to 11.1 but i've already downloaded it and installed it. it still says that i need to download iTunes. what do i do?
Hi conor1221!
You will probably want to download the newest version of iTunes (iTunes 11.1) directly from Apple and install it on your computer if you are having issues updating. The link for the download can be found here:
Apple - iTunes - Download iTunes Now
http://www.apple.com/itunes/download/
Thanks for using the Apple Support Communities!

when i plug in my charger to my macbook and have it charged all the way i can only use it for an hour before it dies on me again. what is wrong with my macbook? what can i do to fix it?
Go to the Apple in the upper left corner and select About This Mac, then click on More Info (and then System Report in 10.7), then select Power from the left hand column of the System Profiler. Copy and paste the Battery Information back here.
Also it would help to know which one of the 9 different models of MacBook you have. To see which model you have go to the Apple in the upper left corner and select About This Mac, then click on More Info (and then System Report in 10.7).When System Profiler comes up check the Model Identifier. -
I have a new computer and when i plugged my iphone in to upgrade it, I lost all of my songs and applications. I need to know how to recover it as I've looked all over the website and my account is empty?
If you are in the USA (is that Pearland, Texas), with iTunes 10.3 and iOS 4.3.3 or later, you can download your previous purchases directly to your iPhone, iPad, iPod touch, or computer.
Here are the instructions: Downloading past purchases from the App Store, iBookstore, and iTunes Store: http://support.apple.com/kb/HT2519 -

Hp pavilion dv6 disables all usb ports when put to sleep mode. hibernate will enable them again.
Im using an HP pavilion dv6 - 6b56el with Windows 7 Home Premium.
First install on 15-DEC-2011
When I put the PC to sleep it will disable all USB ports.
When I restart the box or put it to hibernate (and wake it again) the USB ports wil work again.
This happens when running on battery or connected to a power supply.
As far as I can see I checked all power settings that could possibly disable the USB ports.
I think the latest changes to the system made before this happens were automatic windows updates on 18-DEC-2011 and 19-DEC-2011.Hi,
There are some computers on the market which have special USB port(s) stay awake during the computer in sleep mode. In your case, you can change this using Device Manager under power management tab (un-tick "Allow the Computer to turn off this device to save power").
Regards.
