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.

Where can i find a high speed usb port on the hp pavilion desk top that was purchased new in 2009, thanks, bob


Hi Bob,
Usually the USB ports are either on the front of the unit or you may find some on the back of the unit. All USB ports are now HighSpeed, using the 2.0 delineation. Any port you find will do what you like for that particular unit.
Hope this answers your query.
Please rate and comment, Thank You Joe

It's on the back... its a mini-USB port, not a standard USB port. You have to use a mini-USB to USB cable.

Devise can not be found when putting the dongle in


First I don't know what a bungle is....
But if you have a USB device and it is not beeing seen by computer, remove the device and reboot the unit.
Remove any external devices, such as usb mouse, usb wireless adaptor, ect.
Check your device manager for flags.. or unknown devices.
If you have any of the above with Red X or Yellow flags, remove them.
Reboot the unit.
Check the device manager again.
Plugin the Bungle.
If the unit is not seeing the device, try a differant USB port, as the port you are useing may not be a High Speed USB port and the device may require a High Speed Port.
If the device is still not being seen, check the device on another unit.
Hopre this helps.

USB port defective


Have you tried another USB cable? As long as it's got the same mini-USB connector, they are universal. Most digital cameras use these same cables, as well as many MP3 players and other handheld electronics devices.

If this doesn't fix it, most likely, it's a defective USB interface chip in the unit... and will need to be serviced. GARMIN 1-800-800-1020 (USA).

Fortunately, the USB ports on PC's are protected. When an overload is detected (> 500mA), the USB controller shuts down the offending port. This port can then be restored manually through the USB disgnostics, or simply shutting the PC down, and restarting it.

Overheating


We had a GE 7 port usb port and it overheated and melted----thank goodness I got up when I did or the house would have caught on fire. The only thing we had connected to the usb port was a APC battery backup unit. Any reason why the usb port overheated?
It was pugged into the battery backup unit and I am hesitant to rehook the computer up to the battery backup unit and also will not by another GE usb hub again and whatever hub we do use, I will not plug it into an outlet!
the computer was downstairs and I noticed the odor of electrical burning smell upstairs---the unit was bought nov 25, 2007 and we returned it to BJ'S for a refund today-----I do not reccomend this product to anyone.
