Dell precision not recognising usb 2.0

When i plug a usb device such as an external hard drive or a card reader into any of the 8 usb ports i get a mesage saying i should use a usb 2.0 port for faster data transfers.  To my knowledge they all are 2.0 or at least the ones on the front of the tower, right?  I have tried activating from bios as suggested but i cant find the option in there.  any help would be appreciated.

Sounds not,  some of the older systems only have 1.1, Usb 2 is not all that old (about 2-3 years).
you can upgrade to USB2 bu adding a USB2 PCI card to your system, this would give you some ports on the back and it may be possible to link the ports on the front to the new PCI card to upgrade those as well (depending on how they are connected to the mobo)
you can get USB2 cards with a Pin header which would allow for a pin block connection.

    Hmmm, the spec does seem to state that USB2 are used,

    Have you reinstalled your PC at all?  it is possible that you have not re-installed the chipset drivers completely which includes the USB2 controller, in which case it would all be running at 1.1.



    You can Identify the chipset using thi Intel utility (as this is an intel box)

    Then you can get the appropriate updated drivers for your chipset from the same page (links at the bottom of the page)

How do I upload pictures onto my Dell d600


If your photos are stored on a SD memory card then remove the SD memory card from the camera and insert the memory card into an USB memory card reader. Connect the USB memory card reader into the USB port of your Dell computer. The Dell wiil detect the card reader as an external storage device, you can then open the folder on the memory card that contains the photos and then copy them to your computer.

Most USB hard drives require an external (or secondary) power cable to power the devices when connected to laptop or netbook computers. In some cases, even older desktop computer models will require a similar cable.
This is due to the specifications for the USB standard as it dictates the amount of voltage that a USB port can deliver. Some USB ports are considered "powered" and are sometimes identified by the USB logo and a small "+" sign to indicate the added voltage.
Note: Not all manufacturers use this logo, so if your computer doesn't have this variation of the logo, it doesn't necessarily mean the USB port is not powered.
This added voltage supplies additional current to power smaller devices, such as portable (or 2.5") USB hard drives. However, in the even that the USB port is not powered, then only the minimum amount of current is supplied. This should be enough to slightly power the drive, but not sustain it, thus causing the clicking noise and there isn't enough current running through to move the arm that reads the data on the hard drive.
Chances are that the USB ports on your Asus Eee are not powered and won't allow your hard drive to run until either a secondary cable is purchased or if you use a powered USB hub instead.
The secondary cable looks a lot like a Y-USB cable with one end that connects to your hard drive and the other end consisting of 2 USB plugs that both connect to existing USB ports on your netbook. Between the 2 USB ports, they can draw enough current to power the hard drive - the downside being that if you only have 1 USB port you cannot utilize the cable or if you have 2, they will both be occupying the ports while the hard drive is in use. These cables can cost about $1-7 depending on brand and can be found online in retailers such as eBay & CompUSA.
The USB powered Hub is a more expensive solution, ranging at about $10-25, but is the higher recommended of the 2 solutions since it will provide its own power supply to the tiny device, will use on 1 of your USB ports and since it's a hub, they usually have anywhere from 3-5 additional USB ports (all powered) for you to use, if needed. Some even include built-in memory card readers and they do not require any additional drivers or software to install and can work on any desktop/laptop/netbook.

Dell dimension 2400 usb not working


Hello.

Your Dell has two front-panel and four back-panel USB 2.0 ports.

If NONE of the USB ports are working (and I'm figuring that you have tried other USB devices to eliminate a faulty USB device), this is usually caused by a drive letter conflict. The best way to resolve it is to remove all USB devices, then uninstall the USB controllers and hubs from Device Manager, then reboot and allow your controllers/hubs to reinstall.

If still a problem, use disk management to assign higher drive letters to the existing devices. For example, a permanently connected external hard drive and card reader can be set to V and W. Generally, newly connected flash drives will take the next available letter.

Hope this helps.

USB's slow and external drive


For the USB ports, you may want to verify that the drivers for the "enhanced USB" are up to date and for USB 2.0 or 1.1. USB 2.0 ports are generally backwards compatible for 1.1 devices. The "enhanced" does indicate USB 2.0 controller. 30mins to backup 3GB to your external drive is a VERY long time. USB 2.0 transfers data up to 480mbps, but if you get an error message indicating that the device can perform faster on a 2.0 port, you maybe transferring data at 12mbps which is USB 1.1 speed

To speed up the transferring of data, identify which USB contoller in Device Manager is the USB port you're having a problem with, and delete it from Device Manager. Then, plug in your external drive into a USB port its never used before.

As for the naming of hard drives, Hitachi partners with several drive manufacturers including Dell and IBM.

Sony memory stick pro 128mb has docs on it I need. when i plug it in to laptop, it either doesn't register or says USB device not recognised. help!!!


I'm assuming the docs are important. What I would try to do is buy an external reader which cnnects via USB and hope that it is the port on the computer that is not working.
Sony MRW62E/S1/181: an external memory card reader/writer that can address 17 different memory card formats. It sports a Hi-Speed USB 2.0 interface and draws its power directly from the USB connection. The MRW62E/S1/181 can be connected to both Macintosh and Windows computers. Cost is around $30.

Imstalling internal card reader


Well, installing an internal card reader without a spot on the motherboard, is a little hard to do. I would suggest buying an external card reader. They are a little cheaper, and a lot easier to setup and use, since they just connect to a USB port which all computers have.
