"This device can perform faster...." - but can it really?

Ok, seems like my iPhone 3G does not really support USB 2.0. Every time I plug it in I get the "This device can perform faster..." message indicating that it is running in USB 1.1 mode - even though the port is USB2.0 and if I plug in a USB2.0 external drive into the same port it works like a charm (at full 2.0 speed).
Give how unstable iPhone's been and how often it requires a full reload, USB1.1 speed is just too painful.
Anyone else run into this? Any suggestions on how to make it run at full speed?
Thanks.

I am happy it works for you, it worked for me too for a while... then after one sync suddenly my iPod was empty of all content and most of the apps would not run (yet some did - go figure). The funny thing is that most of the content on my iPod was DRM free MP3's - did not matter, they were all inaccessible).
All in all, even if you are, I am not willing to play Russian roulette wondering with each sync if I will be forced to waste hours deleting and restoring my iPhone (and with USB2 broken, it takes hours and hours) and then re-set up all my email, etc - because those settings apparently are not important enough to be saved by a backup - and then deal with loosing app data. Even if majority of the people do not have this issue, enough people did, including myself.
And by the way, when I was running 7.7.1, the USB problem was there just the same - so the only "solution" to it seems to be to sit and wait for apple to fix it.

T110-107 "This device can perform faster"

Hi, When I move the lid I get the message "This device can perform faster" referring to USB 2.0. The USB transfer rate is very slow after this message appears. Any ideas? Thanks

Then remove all USB ports and USN hub controllers from the device list.
Reboot the unit and wait until all USB ports would be installed again
But its really strange that this message appears moving the lid
The internal webcam is placed in the screen frame its recognized as an USB device in device manager
Maybe you should reinstall the webcam software too
Or you will remove the cam from device manager firstly and would reboot the unit in order to ensure that the webcam would be initialized again

T40 USB "This Device can perform faster" issue

Hi,
OS: Windows XP sp3.
The USB is just using USB 1.1 speed and informs that "This device can perform faster...". I do have google for this issue in an hour now without a solution. The driver on your page is aimed for NT4 system. Where can I find a driver to get the proper speed? Or FAQ post, just something.
Thanks in advance

In your searching, were you able to find this link?: http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-50838
Even though the document refers to Windows 2000, it implies you need the latest Intel chipset drivers for the 845 and 855 chipsets to get the USB 2.0 support functioning.
The latest Lenovo drivers are available from the Thinkpad Matrix here (which are still pretty old):
http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-46058
I had to do something similar (many moons ago) on my old T40, but the Windows XP build I had came with the correct drivers, I just need to use the device manager to update the drivers from the windows defaults to the USB 2.0 version.
Hope that helps.
EDIT:
You can also find information on troubleshooting USB 2.0 device issues here:
http://www-307.ibm.com/pc/support/site.wss/MIGR-4YQHUD.html
The most useful excerpt from that link is probably:
Verify that the USB device is USB 1.1 or 2.0 compliant.
Plugging specific USB 1.1 compliant devices into a USB 2.0 compliant port will cause an error message dialog box to appear. That dialog box details that a non-high speed device has been attached to a high speed port. The device should function normally, but at a slower speed than if a 2.0 device is attached to 2.0 port. Most USB 1.1 devices will function normally in USB 2.0 ports.
In case the issue is with your device(s) driver(s) instead of the USB hub/port driver(s).

Hey looking to sync my iphone with itunes. However it fails to appear in iTunes. I have checked my USB ports and there is an 'enhanced device' present, however when i connect my iPhone 3gs, a pop-up window says that 'This device can perform faster'

Hey, just bought an iPhone 3GS off a friend an am looking to sync it to iTunes The version is 4.3.3. Is this normal ?. The device fails to appear in Itunes however. I have checked my USB ports under device manager and there is an 'Standard Enhanced PCI to USB Host Controller'. Does this mean all my ports are 2.0? When I connect my device it says ' This device Can perform faster' if connected to a USB port. Need Advice.
Thanks

Minimum requirements for the iPhone 3GS for Windows for USB is 2.0.

Since yours says, "enhanced" .. it should be 2.0
Try disabling a/v software and turning off the Firewall then sync.
Disable antivirus software
Turn Windows Firewall on or off

Windows says: This device can perform faster

I have 2 ipods, ipod photo and an ipod video.
When I connect ipod video on my USB 2.0 port, it works fine no errors are shown. But when I connect my ipod photo, I get a prompt from windows saying: "This device can work faster, its a USB 2.0 device blah blah blah"
is it clashing with drivers for ipod video or there is a problem with my ipod?

There is nothing wrong with your iPod. The message is just alerting you to an issue on your system. Basically, you are not getting USB 2.0 speeds, which means whatever storage device you connect to your laptop is transferring data at much slower speeds. Try different USB ports to resolve the issue. However, it is not THAT big of a deal. Usually, i don't care about it because once you transfer anything through Firewire, you would be amazed by USB 1.0/2.0 slow speeds.
You can also turn off the "error" message: In Device Manager, click on the USB host controller, click the Advanced tab and then check the box on the bottom of the window that says “Don’t tell me about USB errors.” Do this for each USB controller in order to prevent this error no matter which USB port you plug you iPod to.
Hope this helped.

X121e 'This device can perform faster' issue

Hi all. I got this problem with my X121e (AMD E-450): when I insert a USB device into the powered USB slot the 'This device can perform faster' message pops up. Any solution? Could it be a software problem (maybe drivers) or hardware problem? I run Windows 7 Home Premium 64-Bit. Thank you in advance.

Try a different slot, and if it connects thru a cable between the device and your X121e, try a different cable. Sometimes it's just a question of how you connect, or even what interference is going on around you. It also might happen if you're connecting a USB3 device, in which case there's nothing you can do (USB2 system I believe).

As far as I know my PC supports Hi-Speed USB 2.0 Port, my question is how can I enable the iPhone the access to it? I also tried using other USB connectors on my PC still in everyone of them I get that Message

The thing is that my Motherboard Supports Hi-Speed USB 2.0, I also enabled HiSpeed in the BIOS and still nothing. I just want to figure out the reason why it doesn't work.
I use Motherboard Asus P5S800-VM-UAYGZ, I don't need any drivers for USB the Windows identified it by itself

This device could perfom faster ?

Hi All
Im running Win 7 64bit and I just got a 2nd usb 2.0 hub and it installed fine but anytime I connect my iphone or other things to it a box pops up say This device could perfom faster and something along the lines about changing to a faster port ?
How do I prevent this from happening, change ports etc ?

Yep, I am having the same issue. I upgraded my wife's and my phones. Her's is a 16GB mine is the 32GB. Using the same PC, iTunes and cable her phone syncs fine and fast w/ no such warning message. Disconnect her phone and hook mine up and it pops the same "This USB device can perform faster if you connect it to a Hi-Speed USB 2.0 port." message and mine syncs painfully slow.
Opened a case on this and talked w/ support rep, he stated it's a problem w/ my USB port and the larger HD in my phone. "What???" I said, "How can that be if one phone works fine and one doesn't?" His response was for me to go buy a USB 2.0 card and see if that works because it may be a HW issue w/ my USB port.
I suggested it may be a HW issue w/ my phone at which point I was quickly corrected that it could not be.

USB Device will perform faster

Hello! I just bought a MSI K8N Neo-V V2.0 (MS-7030). Everything were ok. But everytime I plug-in my usb storage devices, a message on the task appears and it says.. "USB Device will perform faster.....bha..bha". Is this means that this mb is not support high-speed usb? What model thus MSI mb's that support high-speed usb? Please help...:(

Quote from: jelodavid on 03-July-06, 12:55:33
I found out that my MSI mb only support USB1.0 not 2.0 according to PC Wizard. But according to its manual, USB 2.0 is supported. MSI manual did lie to me. Anyway thanks for very big help.
That is impossible. The board DOES support USB 2.0, the manual is not lying.
You are not understanding Richard's suggestions, OR, you have not acnowledged if you tried what he suggested.
Are you using an XP installation disk with AT LEAST Service Pack one?
And, have you installed the correct chipset drivers for your motherboard Click Here>>> For nVidia Drivers

Nano 3g - USB "this device can perform faster" report

I occasionally get this error when I connect my 3rd gen nano - though most of the time it corrects correctly (Dell OptiPlex desktop, Windows 7 32-bit). I've double checked all the "usual suspects" - tried two different USB cables, different USB ports, checked that all drivers are up to date, yet the error persists. It seems to be specific to this nano, as neither my 2nd gen (synced using the same cables) and my 7th gen ever give the error. I've reset the nano, checked that its software is up to date, etc. Any thoughts on why this may be showing up as an occasional issue, and any further remedies I might try?

When i plug in my Ipod i get a strange message "this device can not be used because the apple mobile device service is not started."

What does "This ipod can not be used because the apple mobile device service is not started" mean. After I updated my Itunes I get this message when I plug in my Ipod and it doesn't come up in Itunes.

If you are using Windows 7, go to:
Control Panel>Programs>Programs and Features
Look for a program called 'Apple Mobile Device Support'
Right-click on it
Click 'repair'
Wait until the repair operation is complete, and voila, your problem should be solved, itunes will recognise your iphone/ipod once more. This worked for me.

When i go for creat a icloud account it showed this device can't .

can anbody help me how solve the above listed problem .

Since you posted in the iPhone forums, I assume you are trying to create the account from your iPhone running iOS 6.1.3, yes?
Any given device can only create up to 3 iCloud accounts in its lifetime. If your iPhone has already been used to create 3, then it will never be able to create another one. The limitation is tied to the hardware address/ID of the device, not the user(s) of the device.
You would have to find another Apple device to create the iCloud account with. Once created, you will be able to log in and use that account on your current iPhone.

"This device can perform faster...." - but can it really?
