【 Weak current College 】 USB peripherals product use four cream

As the popularity of the USB standard, now more and more peripherals for Office products (such as a USB scanner, printer, card reader, etc.) are using the USB interface, but some incorrect usage tends to bring many problems, so find out their usage considerations, you can reduce a lot of trouble.

1. cream installation Duke

New buy USB products don't hurry to install, first enter the BIOS and make sure the USB interface settings are not open, so you will not be able to identify the mistaken for product problems! open computer, press DEL to enter BIOS, "USBLegacySupport" set to "AUTO", "USBFunction" is set to Enabled. If you are using the onboard USB3 or USB4 interface, but also the "OnboardUSB" is set to Enabled. Also if your motherboard is older, it is best to use the Flash disk in the BIOS before refresh, and better compatibility, to make any mistakes.

After installing the USB device, it is best to "Control Panel → System → Device Manager" to see if there's a device with a yellow exclamation mark, so that you can tell you have installed the wrong driver, if you have to delete it, and then click the "Refresh" and manually specify the driver path, can generally be installed correctly. If you are the best in Win2000 is wrong driver uninstall instead of directly deleted, otherwise the system will assume that only temporarily deactivate the device, there is a conflict may arise in the future.

2. cream incorrect plug USB products

Using the USB interface products support hot swap, but it cannot be pluggable. First of all not in its working for pluggable. For example, the scanner is pulled down in the middle of work can easily scan head does not reset or to deviation, it will affect the precision. Especially on the USB Flash disk, hard drive storage devices such as mobile should pay special attention to this point, because this may damage where all data, generally only format before it can be reused. Also not in a short time to frequently swap Flash disk, because when the product is plugged into the USB interface, the system requires some time to react, and immediately put it pull down, the most likely cause a system error, so the best interval seated at 5 seconds or more.

3. cream use inferior USB extension cable

Sometimes, out of office equipment placement considerations, often equipped with USB extension cord, but some other brand of extension cords are of poor quality, especially in the interface, not too loose or too tight. Too bad the pine is easy, even when the use and impact are falling off. Too tight and not conducive to plug a lot of times easily in Flash disk for scratches on the USB port, thereby causing corrosion, never in this small article on provincial money. Additionally extend the line length and not too long, otherwise it will affect the data transfer.

4. the cream too humid environment

For a variety of companies considering some printer room arrangements in more remote small corner, relatively poor, especially with regard to ventilation and environmental humidity. So once the rainy season, humidity increases, exposed outside the USB interface it is easy for rust, resulting in poor contact, affecting normal data transmission. Then the best approach is to strengthen ventilation drying, for less common machine also periodically post to off the moisture.
