If you are plugging into a laptop USB port you may need an external power supply for the external port. Laptop USB ports have a lower power rating than desktops, to conserve battery power. Generally all you should need to do is plug in the USB device and the operating system should find the required drivers.

SOURCE: Usb Ports problem

Is this your personal computer or is it a company computer that is joined to a domain?

Some companies set policies to ban USB usage to protect their data.

If you have the administrator user password try to login with that and see if you can access your USB device.

SOURCE: hi i have a R32 think pad.... it cant support my

Your laptop has USB 1.1. It won't support anything running 2.0 because of power constrictions. 2,0 has a power line and 1.1 does not. as far as upgrading the hardware, the chipset is not designed for 2.0 so it will run a 4 port 2.0 as 1.1 because there is no provision for power (voltage). Hope this helps.

Ultra SuperSpeed USB


usb speeds b> A USB, or Universal Serial Bus, is the brainchild of Intel developer Ajay Bhatt. USB is useful for transmitting data and power to devices. USB cables are widely used in 2010 to connect computers to such devices as printers, cameras and flash drives. While the USB port was initially developed for computers, it has become standard for video game consoles, smart phones, PDAs; it can also function as power cords for these devices.
Unit Load Capacity
USB comes in 1.0, 2.0 and 3.0 versions. Each provides between 4.75 and 5.25 volts (V) of power that travels between one wired line. Various devices may draw this amount of power from that single, wired line. A maximum of five unit loads can be drawn from a USB 2.0 port, however six unit loads can be drawn from a USB 3.0 port, making it capable of delivering more power to devices. USB devices are configured to support a minimum of 100 milliamps (mA) times the number of powered ports it contains (200mA for one port, 300mA for two ports, etc.). b> Charging Devices b> Many devices can draw power to recharge their batteries or can function off of power currents running through a USB port cord. Superspeed USB ports run off a 3.0 platform and optimize power usage to provide the minimum amount of energy the device needs to recharge or run. New powering modes allow USB ports to supply power and communication (data transfer) concurrently. A USB Charging Downstream Port can supply up to 1.5 amps (A) at low-bandwidth transfer rates and 900mA at high bandwidth rates. A portable device such as a phone or PDA can draw up to 1.8 A from a Dedicated Charging Port on a USB 2.0 or higher device. In 2009, major cell phone manufacturers like Nokia, Motorola and Samsung agreed upon a standard, universal micro-USB charger for all their phones. In time, this will eliminate the need for manufacturers to provide charging cables with their phones. This micro-USB device has been adopted by the International Telecommunication Union as its universal mobile phone charger solution. When a device requires more power than can be delivered by a single USB port, that device may be charged with a multi-ported USB. External hard drives, for example, can be powered by a USB cable that connects to an external power supply on one end and to a device on the other. b> Powered USB b> A powered USB is a self-powered USB that uses additional power lines than standard USB ports to deliver more electrical current to a device. It uses four extra pins to supply 6 A at either 5 V, 12 V or 24 V to attached devices. Powered USBs are used to power retail devices like barcode scanners, printers, pin pads and signature capture devices. These USBs consist of two ports: a top one which accepts a USB cable and a bottom one which accepts a power cord. The powered USB allows devices to draw more power from a USB and not require an external power source to operate.
USB Power Options
b> According to Everythingusb.com, the Universal Serial Bus (USB) is a concept that was originally designed as a connection for smartphones to computers in the 1990s. Since then, the USB has evolved from the older USB 1.0 and 2.0 designs to the faster USB 3.0 model, which is also called the "Superspeed USB." A benefit of USB is that it can be used to power devices without requiring any additional power cables or plug packs.

Low-Power USB
Low-power USB devices typically consume 100 milliampere or less from the USB bus. This is called a single-load unit. USB 1.0 and 2.0 devices have a single-load unit of 100 milliampere, and for the newer USB 3.0, the single-load unit is redefined to 150 milliampere. Low-power USB devices can be plugged into any USB host or hub port. Low power bus powered devices use the so-called "V bus" pin to draw its power and run on a voltage of between 4.40 volts up to 5.25 volts. A low drop-out regulator is required for most 3.3 volt devices. b> High-Power USB b> High-power USB 2.0 devices consume between 101 milliampere and 500 milliampere (1 to 5 load units) to run on. USB 3.0 supports power consumption of up to 900 milliampere (6 load units). These devices can be plugged in to any USB port, but if you are using a USB hub, the device will only be able to draw 100 milliampere unless the hub is self-powered. High-power USB devices run on a minimum of 4.40 volts. b> Self-Powered USB b> Two types of self powered USB devices exist: true self-powered devices that rely completely on their own power supply, and hybrid self-powered devices that also draw some current from the USB bus. Hybrid self-powered USB devices typically draw up to one load unit from the bus and use their own external source for the rest of their power. Most of these devices have a safety feature to ensure that they don't try to draw more power from the bus, should the external source fail. High Speed USB Port Since 2002, Microsoft has supported high-speed USB ports in the Windows XP operating system. Prior to 2002, computers and operating systems used the USB 1.1 standard, with its 12Mbps maximum data transfer rates. USB 2.0, also known as "Hi-Speed," pushes the maximum data transfer speed to 480Mbps. To take advantage of the higher speeds, you'll need to install a USB 2.0 card in your computer. In most cases, desktop users will need to install an internal card, while laptop users with PC Card or ExpressCard slots may install external cards.
Purchase an internal USB card or internal USB drive bay. Shut down your computer. Remove all cables and peripheral devices. Remove the left side panel (when facing the front of the case). Remove any screws or adjust any latches. The method of removing your side panel will vary according to the type of case you have. If you are unsure of how to remove your side panel, see your case or computer documentation. Attach the anti-static wrist bracelet's clip to a metal object. Strap the bracelet to your wrist. Locate an empty card slot. Remove the card slot cover by unscrewing the screw and lifting the cover, if applicable. Line up the hardware with the slot to ensure that you are inserting it in the correct direction. Insert the card into the slot until you hear a click. Do not force the card. Remove it if you're having problems. Then line up the card with the slot again and try to insert it again. Secure the card into the slot with the slot cover screw you removed earlier. Replace the side panel. Screw in any screws you removed earlier. Attach all cables and peripheral devices to your computer. Restart the computer. Windows will automatically detect your new high-speed USB port. b> Install an External Card b> Turn on your computer. Locate an available PC Card or ExpressCard slot. Insert the card into the slot. The card will click when seated. Allow your operating system time to detect the high-speed USB port and to install the drivers required. Hope this helps.

I have 3Q HDD External, and my usb can not see it everytime, every 5 minutes i can see it everytime...


hallo there, sounds like your usb bus does not have either the needed power to handle the external device and capacitors which provide could be defective, which means they are loading up and then unloading which brings a usb stop up. otherwise check your system configuration for your usb port. power usage can be defined per port on either nix systems as also on M$'s;
other option is the power supply is of cheap make and the hardware inside cant handle the power needs.
1st: check usb port power definitions,
2nd: try other port
3rd: try other power supply

P.S. sounds maybe stupid but have you tried other usb port? some of the ports provide extra power as for un-powered hdd's.
Look in the manual of your handbook as for how much power is supplied by the divers ports.

Why can't I access anything that was copied onto my Toshiba 500G external harddrive. The computer doesn't recognize the program that made any of it, even though it's the same computer.


It is very possible the voltage on your computer's USB port is not handling the load. I would buy a "powered" USB 2.0 hub, plug it into your computer's usb port and plug the harddrive into the powered hub.

Restart the compuetr and try again. be sure that the USB cord to the external HD is NOT plugged in when the computer restarts until Windows has been loaded completely.
You can also try a different USB cable and a different USB port on your laptop

My external hard drive wont conect to my computer.


Is this a new drive? has it worked before? the usual sequence is to connect the external drive to a power source first, and then connect the usb cables to the PC. IF you know the usb cables are good and have verified that they are connected properly, try connect to a different usb port on the PC, sometimes ports go bad. If that still doesn't work, the most likely the hard drive has gone bad.
