Why do the problems keep happening? How can we solve them? There are two issues that can cause the problems.

Case 1: Device Driver is installed improperly or damaged.

A USB device (like Printer, scanner, joystick and other hardware) needs suitable driver to be recognized by Windows system and work properly on the computer. When you buy a new USB device you need to install the driver for it first. Or your system will pop up the error messages and you will not be able to use it.

This problem not only happens to new hardware but also old devices. Because driver files are easily damaged or deleted by some illegal operations or viruses. When a driver is damaged, the corresponding device will not be recognized and cannot work properly. To fix it, you can download the latest driver for the device and install it on your computer.

Case 2: USB Driver damaged or outdated.

If you have installed the latest driver for the device but it still does not work, then your USB driver is probably damaged or outdated. USB driver is used for recognizing a USB device that is plugged to the computer. If the USB driver is damaged or outdated, Windows will not be able to recognize all the USB devices that plugged to the computer. And the USB devices attached to a computer will be deemed to be Unknown. The only way to fix the problem that caused by damaged and outdated USB driver is update or reinstall it.

In a word, the USB unknown device error results from driver problem. To fix the problem, you need to reinstall and update the device and USB drivers on your computer.

Among the most common brands in the market for the Handheld Barcode Scanners nowadays are Symbol, Metrologic, Wasp, Adesso, TS, PSC, CCD, CK1, Intermec, Trakker, Datalogic, Standard and Informatics. Though there are a number of brands available, they come with different features for each piece. The weight alone vary, some weigh as little as 9 ounces while others weigh up to 3 pounds. Some are slim while others are more bulky, there are also some which are connected by USB ports and wires while others are wireless and are connected via Bluetooth. For Handheld Barcode Scanners which are wireless, the hand held scanner is powered by a battery; each fully charged battery can scan up to 20,000 scans or can stay on for up to 30 hours. The standard line or range is one hundred and sixty feet; although for some models, there is still room to be able to scan and store outside these lines for one to twelve inches away from the boundary by using the memory mode. For those models which are connected with wires to a station, these can normally extend for up to 5 feet which makes moving it around easier than that with a very short cord. These hand held scanners are now more usually featured with a plug and play feature via a USB plug; this will enable one to instantly connect the scanner to the port station without having to install it with a separate software.

If one is to consider purchasing one of these , there are a few factors to consider to be able to make a wise decision. They would have to first identify the purpose of its use for them to be able to make the right decision. The first thing to consider should be what type of bar code will be scanned; there are two types; the 1 Dimensional and the 2 Dimensional barcode. A one dimensional barcode is that which is most common; these come in a series of vertical bars of different densities thus forming a rectangle. However, for codes which require more information, these are the 2 Dimensional barcodes which looks quite different and may seem like a small pattern, sometimes come in boxed images. The orientation of how the barcode will be scanned is another factor; the most common Handheld Barcode Scanner is the one which has linear beams; this is only effective when the scanner has been positioned to be perpendicular to the barcode.

The other type is the omni Directional scanner; this is where the scanner is effective in scanning barcode regardless of the orientation of the barcode-may it be horizontal, diagonal or vertical, it will still be able to read and interpret the bars. If the scanner will be used in a specific station much like that of a check out counter, they can opt for the standard scanner which are wired and ported; however, for more versatile needs such as back room or inventory scans, the wireless version or the Bluetooth and memory mode featured scanners would be a better fit. Both the warranty and guarantee of the product will play an essential role in purchasing a scanner; if it will be used in a small scale purpose or business, an extended warranty or those up to 5 years or so may not be required; however for those Handheld Barcode Scanners which will be used in industrial environments and will require a huge number of scans and storage needs, those models with specified warranties which extend for long periods of time may be more essential.
