The fact that it is wireless allows users to bring this portable device with them to the library, to work or at the café.

The second benefit of the wireless USB hub is that it is compatible with a variety of operating systems. This means that users can use it with Windows or Mac. Some USB hubs may also work with Linux operating systems. This is ideal for those who have two different types of computers, or are considering purchasing another computer later in life. This also allows the ease of sharing files amongst friends and family members.

Features of a USB wireless hub include software, user’s guide and a battery. However, the USB hub may run strictly on Wi-Fi, which means that the user will need to have wireless Internet running through his or her home. The user’s guide and software helps users to quickly and easily set up the hub for instant access. All they need to do is insert the CD into their personal computers’ drives. The installation wizard will then guide them through the process.

Those interested in a USB wireless hub can find them either online or at retailers nationwide. Both computer and electronic retailers also carry these types of hubs. They may also want to purchase them at online computer and electronic retailers if they want to “comparison shop”. Comparison shopping allows them to look at the varying brands, features and prices.

In this world of technology, people have multiple devices. They not only use a computer, but they use a copy machine, a fax machine, a printer, and a scanner. On top of that, they may use portable devices such as cell phones, digital cameras and MP3 players. This becomes difficult for those—especially families—who have a limited amount of USB ports on the computer. A 7 port USB hub helps users connect multiple devices to their personal computers or laptops.

The features of a 7 port USB hub is as follows: it has seven ports, software, guidebook and user’s guide. The seven ports work with any portable or electronic device with a 2.0 USB cable.

The first benefit of a 7 port USB hub is that it is compatible with most operating systems. This is ideal for users who use both a Mac and Windows operating system. They have the ability to transfer the USB hub between computers. If portable, users can use the device at libraries, at work or while on the go. This is also a benefit for those who want to purchase a different operating system down the line.

The next benefit of this USB hub is that it is compatible with both 2.0 and 1.1 USB ports. This device can backtrack to a 1.1 USB port if necessary. No longer do users have to search for a USB hub that is compatible with a certain type of USB port. Not only is it compatible with a 1.1 USB port, but it uploads at speeds up to 480 megabytes per second (Mbps). This means that they have the ability to upload multiple files at once, if they choose.

Those interested in a 7 port USB hub may find them at retailers nationwide. Some retailers include Kmart, Walmart and Sears. Electronic and computer retailers also carry 7 port USB hubs.

Those who need more USB ports should consider shopping for 4 port USB hubs. These hubs allow computer users to connect a computer, print, scanner, fax machine and copy machine, or any other device with a USB connection. They also have the ability to connect smaller devices such as cell phones, iPods and MP3 players or digital cameras. Four port USB hubs also are an ideal option for large families who need to plug in various devices. Those interested in these types of hubs should learn about the features and the benefits.

The obvious features include four USB ports which allow users to connect multiple electronic devices. These hubs also come with software, a USB cable, guidebook and limited warranty. The USB cable easily connects into any desktop computer or laptop. A quick startup guidebook and software allows users to easily connect their four port USB port to their computers. The warranty varies on the type of USB hubs that users purchase.

The first benefit of 4 port USB hubs is that they work with any operating system. Operating systems include Windows, Macintosh and Linux. Computer user should be aware if the USB hub is compatible with the operating system they are currently using. Those who have two different computers, or are considering purchasing a second computer may want a USB hub that works with all operating systems.

The next (and last) benefit of a 4 port USB hub is that it has faster upload speeds. Users have the ability to transfer large files at speeds up to 420 Megabytes per second (Mbps). This means that they can upload songs, pictures, videos and documents, either one by one or all at once if they choose to. The indicator light on the USB hub lets users know when upload is complete.

Those who want a 4 port USB hub can find them at any retailer. They also will find these USB hubs at both electronics and computer retailer nationwide. Online shopping websites such as Amazon and Overstock carry USB hubs as well. Users have the ability to search for these devices through any search engine.

Hub USB is practical for todays’ electronic devices, and makes ports conveniently accessible. They are also very surprisingly affordable at a price range between $14.00 and $62.00. This device makes it possible to turn a single port into 4 to 7 ports. This allows for more devices to be connected to the host system.

A Hub for USB can extend your network to up to 127 individual ports. Most ports that are already on your desktop are located at the back of the computer. With a USB Hub, one can connect to the port in the back of the computer, and extend up to 7 ports to the front or side of the computer. This will allow for the attaching of peripheral devices like printers, faxes, and scanners to be supported by the same network.

There are primarily two types of hubs. There is the self-powered hub that derives its power from a wall outlet. These will usually provide up to 500 milliamps at each port. Then there is the bus-powered hubs. These plug in to the computers’ USB bus and obtain all their power from the bus. These ports have to split the total 500 milliamps among the ports.

The self powered hub can connect to digital cameras, card readers, keyboards, mice, MP3′s, and memory sticks. The major consideration in the purchase of a Hub USB, is whether it is 1.1 or 2.0 compatible. The 1.1 compatible are capable of transferring data at speeds up to 12 megabits per second.

The 2.0 compatible have the ability to transfer data at speeds up to 480 megabits per second. The 2.0 is also backwards compatible. This means that they have the ability to read and translate the 1.1. While they can read and transmit 1.1 data, they cannot make their speeds any faster. The 1.1 has the 12 megabit capability, and with the 2.0 it retains that 12 megabit capacity.

Hub USB’s typically come in 4 and 7 port abilities. They all perform pretty much the same task. It just depends on how many external devices one needs to hook up.

When a device does not work as it is intended, there may be an issue with your system. The annoying part about maintaining computers is finding the source of the problem. After searching for possible solutions, you come across a topic: “USB hubs not working.” This is a common problem that every computer troubleshooting specialist undercover when fixing PCs. But you do not need to be a seasoned expert. Here are a few reasons why and ways to fix USB hub problems.

- Drivers: Device drivers of a video card, audio card, and other PCI, AGP, especially USB devices are known for causing system instability. To find the issue, go to the Start Menu, right click on the “My Computer” icon and select “Properties”. Click on the “Hardware” tab and you will find “Device Manager.” You will find “Problem Devices” with items marked by a yellow question mark. Reinstalling or upgrading drivers usually fixes this problem.

- Faulty devices and cords: If a driver fails to correct the issue, bad USB plugs, whether an older generation such as USB 1.1, or a USB plug with bad wiring can cause problems with certain USB hubs. If the cord is replaceable, find a new one with a “USB 2.0 certified” label. Also when using a USB device, be sure to find the label to avoid problems in the future.

- Motherboard: If the motherboard has built in USB ports, refreshing the CMOS battery and upgrading the BIOS is another method, but are intended for advanced users. It requires opening the computer and handling parts sensitive to static electricity. Be sure to back up any important information from the hard disk and the BIOS settings, and unplug everything from the PC and ground yourself first before doing this.

Find and remove the screws from the backside of the PC and slide it open, depending on the type of case. The battery is a medium-sized button cell battery and is normally located around the CPU area of the motherboard. Remove the battery for 10 seconds and insert it back into the compartment. Close up the PC, reconnect the power and reboot. If you saved the BIOS settings, you can import them to restore your original settings.

- BIOS: If the motherboard’s USB hubs are still not working or prefer not to go inside the PC, upgrading the BIOS is a safer solution. The same backup precautions apply as above. This is also an advanced method and must be handled carefully. Find the vendor of the motherboard from the PC manufacturer, or visit the company’s website if you custom built your computer, and download the latest BIOS firmware. Follow the instructions carefully to update the BIOS. After the upgrade process is complete, import your original BIOS settings and reboot your system.

If the USB hubs are still not in working order, you may need to replace the motherboard completely. Also purchasing an internal PCI USB Hub is an option if you would like to keep your current motherboard when other problems are not present.
