Two solutions would be to either restore your pc to before the problem started,using system restore on accesories menu, or use the recovery cd or the recovery folder Acer laptops usually have on the 'D' drive and re-install usb controllers and drivers.

Be safe rather than sorry, get yourself a Powered USB Hub.

One of the problems with USB is that a device is only allowed to draw up to 500mA of power (100mA on first connection). So, if you buy a non-powered hub, it will only support one high-power (500mA) peripheral, and the other ports on that hub may be useless. Plug a mixture of devices into a non-powered hub and some might work while others might not. Since people expect to be able to plug any USB device into any USB port, I think this is really bad. Using a powered USB hub generally eliminates the problem.

My apple ihone is disabled connectto itunes


There are many reasons why iTunes will not recognize your iPhone, whether it's dust or dirt blocking your dock connector or a system setting gone wrong. No matter what model iPhone you have, here are a few suggestions for helping the problem of iTunes not recognizing iPhone:

1. Generally speaking, when iTunes does not recognize iPhone, it may have something to do with the version of iTunes. If you are using an old version of iTunes on your computer, it may not be capable of recognizing your iOS devices. So updating iTunes to the latest version is a fastest way to get the problem solved.

2. If you are running iTunes in the latest version, but still can't get your iPhone recognized, you may want to take a look at your computer, sometimes if your computer lacks necessary software, it might lead to the malfunction of iTunes.

3. USB port on your computer can be another reason why iPhone not recognized by iTunes. So you can try more than one USB port to see whether the USB port works well.

4. Of course, your iPhone may also be the cause of iTunes not recognizing iPhone. At this moment, you can restart your iPhone by holding the Sleep/Wake button and Home button at the same time until you see the Apple logo, then connect iPhone to computer with USB cable again.

5. You should also make sure your iPhone trusts your computer, because after changing a new system on computer, your iPhone will regard it as a new computer. What's more, you should check out whether Apple Mobile Device Support is installed on computer.

6. After checking out all the aspects mentioned above, you can try to connect iPhone to computer with the USB cable again.

If none of these methods work out, you may want to try set your iPhone up as new after iTunes not recognizing iPhone. You only need to tap General > Settings > Reset > Erase All Content and Settings, and then choose Set Up as New. When you have set iPhone up as a new device, you are able to connect iPhone to computer with USB cable. But before erasing all contents on your iPhone, you may want to back up iPhone files to computer to keep them safe.

USB port for iphone sync


The iPhone will sync to iTunes on a computer. If the display has a USB port, there must be another USB cord to the computer. The iPhone will go through it to get to the computer.

My iphone says disabled connect to itunes but itunes doesnt read.


Have you tried using a different USB port? Sometimes certain USB ports on a computer stop reading the device. Try using a different computer. See if that one reads it.
If all else fails, you may need to DFU-Restore the iPhone.
In order to do that:
1. Turn off the phone. 2. Hold down the power (the top right) and the home buttons. 4. Once the apple logo comes on, stop holding the power, but keep holding the home button. 5. Open up iTunes. It should say the phone is in restore mode. 6. Do your restore.
Cheers.

How to set up my iphone


here are useful tips for your iphone set up.


Please read the Activating and Setting Up Manual Instructions below -
What You Need - To use iPhone, you need:
• A new wireless service plan with the carrier that provides iPhone service in your area
• A Mac or a PC with a USB 2.0 port and one of the following operating systems:
• Mac OS X version10.4.10 or later
• Windows XP Home or Professional with Service Pack 2 or later
• Windows Vista Home Premium, Business, Enterprise, or Ultimate edition
• Display resolution on your computer set to 1024 x 768 or higher
• iTunes 7.5 or later, available at www.apple.com/itunes
• An iTunes Store account (a major credit card is required to open a new account) â An Internet connection
Activating iPhone
Before you can use any of iPhone's features, you must activate iPhone by signing up for a service plan with the iPhone service carrier in your area and registering iPhone with the network. If you already have a wireless account with the carrier, you may be able to upgrade your account to work with iPhone, or keep using your old phone and add a new line for iPhone. (Some accounts may not be upgradeable.) You may also be able to transfer your current phone number to iPhone, or get a new one.
For more information about iPhone, including videos about how to activate and use it, go to:www.apple.com/iphone
Inserting the iPhone SIM Card
In some regions, you may need to purchase the SIM card separately and insert it into iPhone before activation. Read the documentation that comes with the SIM card for instructions.
If your carrier gave you a PIN number to use with your SIM, you may need to enter the PIN before activating iPhone.
Activate iPhone
1 Download and install the latest version of iTunes from www.apple.com/itunes.
2 Connect iPhone to a USB 2.0 port on your Mac or PC using the dock and cable that
came with iPhone. Unless your keyboard has a high-powered USB 2.0 port, you must connect iPhone to a USB 2.0 port on your computer.
3 Follow the onscreen instructions in iTunes to activate iPhone and sync iPhone with
your contacts, calendars, email accounts, and bookmarks on your computer. A single checkmark in "Set Up Your iPhone" syncs all these items automatically. Or you can use iTunes to customize the information you sync, and to sync your ringtones, music, photos, podcasts, and videos to iPhone. See the following section.
You can disconnect iPhone from your computer after "Waiting for activation" appears on the iPhone screen. When activation is complete, "iPhone is activated" appears on the iPhone screen. This means that iPhone is fully functional and you can use all of its features.
Important: If you are migrating your current phone number to iPhone, activation may take from several hours to a day and migration of your number may take several days, depending on your location and previous carrier.
Syncing iPhone with Your Computer
When you connect iPhone to your computer, iTunes syncs iPhone with the information and media on your computer, according to how you've configured the iPhone sync settings in iTunes.
You can set iTunes to sync any or all of the following:
• Contacts - names, phone numbers, addresses, email addresses, and so on
• Calendars - appointments and events
• Email account settings
• Webpage bookmarks
• Ringtones
• Music and audiobooks
• Photos
• Podcasts
• Videos
Ringtones, music, audiobooks, podcasts, and video content are synced from your iTunes library. If you don't already have content in iTunes, the iTunes Store (available in some countries) makes it easy to purchase or subscribe to content and download it to iTunes. You can also add music to your iTunes library from your CDs. To learn about iTunes and the iTunes Store, open iTunes and choose Help > iTunes Help.
Contacts, calendars, webpage bookmarks, and photos are synced from applications on your computer, as described below. Contacts and calendars are synced both ways between your computer and iPhone. New entries or changes you make on iPhone are synced to your computer, and vice versa. Webpage bookmarks are also synced both ways.
Email account settings are only synced from your computer's email application to iPhone. This allows you to customize your email accounts on iPhone without affecting email account settings on your computer.

Iphone will not restore error 13


You can resolve the restore issues using the troubleshooting steps found in this document:

1. Update to the latest version of iTunes

To see if you have the latest version of iTunes, open iTunes and check for updates.
  • Windows: Choose Help > Check for Updates
  • Mac: Choose iTunes > Check for Updates
If there is an update to iTunes available, install the update and try to restore again. If you do not have an active connection to the Internet, or your Internet security settings are configured to prevent iTunes from communicating with Apple, iTunes will alert you that the iTunes update server could not be contacted. Resolve your Internet issues and attempt to update again.

2. Restart your computer
Simply restarting the computer can clear up certain issues that could prevent you from restoring iPhone or iPod touch. After you restart, try restoring the device again in iTunes.

3. Open the proper ports and allow access to Apple servers
During the update and restore process, iTunes needs to contact Apple. Ensure that your computer has the following ports open and can access these servers:
Port 80
Port 443
phobos.apple.com, albert.apple.com, gs.apple.com
If you see "Error 9807", you must open access to the following VeriSign servers:
evintl-ocsp.verisign.com
evsecure-ocsp.verisign.com
If you are using a Windows operating system, you can follow this article to help resolve issues caused by third-party security software.
You may need to update, properly configure, disable, or uninstall built-in firewalls and other security software to prevent interference with iTunes. For assistance with this, contact the company that supports the firewall or security software you use. If you are using proxy settings, try to restore or update without using a proxy.
4. USB Troubleshooting
Connect iPhone or iPod touch to a different USB port on your Mac or Windows PC. USB 2.0 ports that are built in to the computer are preferred over a hub. If you tried connecting iPhone or iPod touch to USB ports on the front of the computer, try connecting them to rear USB ports. After doing this, try to restore the device in iTunes.
If the issue continues:
Remove all USB devices except the keyboard, mouse, and iPhone or iPod touch. Remove all USB hubs and connect directly to the computer.
Connect iPhone or iPod touch directly to the included USB cable, bypassing the dock.
Restart the computer.
Try to restore the device again in iTunes.
If available, test with alternative, known-good USB cables.

5. Restore on a different computer
If the issue is not resolved with the above steps, try to restore using a different computer. Ensure that the computer you use has USB 2.0 ports, the latest version of iTunes, and that you connect directly to the computer.
If another computer is not available, proceed to the Advanced Steps below.

My iphone won't sync with itunes. it did at first but now keeps coming up with an error I have an original iphone, never been jailbroken or any such thing, and can not currently get it to sync with itunes...


Recharge
Make sure iPhone is charged. Connect to a USB port and look for the lightning bolt battery icon in the upper right. If you don't see this icon, then iPhone is not charging. The battery will charge to 80% in an hour.
Note: If you put your computer into sleep mode while iPhone is connected via USB, iPhone may not charge.


This screen means to keep iPhone connected so it continues charging. Please note:
If iPhone is not sufficiently charged it will not show up in iTunes
Use a high-power USB port such as the one on your computer, or use your iPhone AC adapter.
Don't use the USB port on your keyboard because it is a low-power port and iPhone will not charge.
Make sure you are using USB to charge. Accessories that use FireWire to charge are not supported with iPhone.
If you see the red part of the battery image flash three times and then the screen goes black, it means that iPhone is not receiving power to charge.

If the above steps dont resolve follow the following steps :
Retry with a different USB port.
Note:
Don't use the USB port on your keyboard because it is a low-power port and iPhone will not charge.

If the above steps dont resolve follow the following steps :
Restart

Try restarting iPhone. To turn it off, press and hold the Sleep/Wake button until the red slider appears. Slide your finger across the slider to turn off iPhone. To turn iPhone on, press and hold the Sleep/Wake button until the Apple logo appears.

Does iPhone appear frozen or stuck? Try pressing and holding the Home button for at least 6 seconds to close a frozen application. Then try restarting iPhone again.

Note: If that doesn't work, try restarting your computer.
If the above steps dont resolve follow the following steps :
Reinstall

Reinstall iTunes 7.7 or later.
Get the latest version of iTunes (7.3 or later) from http://www.apple.com/itunes/download/

Thanks.
