HOW TO FIX USB PORTS PROBLEM

USB Problems

What to do when it won’t plug nor play

Problem: Some USB Ports Don’t Work

Solution: Nonfunctional USB ports could be caused by a few things. If the ports are front-mounted, make sure the internal cables are connected properly and that the requisite USB header is enabled in your system BIOS. If the ports are soldered on the motherboard (and enabled), open up Device Manager and see if any USB root controller or hubs are reporting a problem. If so, a driver update/reinstallation may resolve the issue. It’s also possible that the physical connectors have been damaged (or a fuse has blown), in which case you’ll have to re-solder some new ones onto the board. If the USB ports are associated with a third-party controller, be sure its drivers are installed, because Windows may not recognize the controller automatically.

Problem: Slow File Transfer over USB

Solution: Windows Vista and 7 have some known USB performance issues, so the first thing to do is run Windows Update and make sure your OS is fully patched. We’d also advise installing the latest drivers for your motherboard’s chipset and any discrete USB controllers. You could also try setting the USB drive to performance mode. Open Device Manager, right-click the USB drive, and choose Properties from the menu. In the resulting window, click the Policies tab and tick the option labeled “Better performance.” Please note, this feature will enable write caching, so you’ll have to use the Safely Remove Hardware option when disconnecting the drive to prevent any data loss.
Problem: USB Hub Doesn’t Work

Solution: This problem is almost always caused by insufficient power being supplied to the hub. If the hub came with an AC adapter, make sure it’s plugged in and working properly. And if you’ve got the hub plugged into a front-mounted USB port, try connecting it to a rear port that is soldered onto your mobo. Rear-mounted ports can usually provide more power (or more stable power), which can resolve some issues with finicky hubs.

Problem: Charging Phone over PC’s USB Port Takes Forever

Solution: Standard USB 2.0 ports connected on a root hub have to share 500mA of current (USB 3.0 powers up to 900mA). If you’ve got a bunch of USB devices connected and the port your phone is plugged into is competing for limited power, it will take much longer than normal to charge. Try plugging the phone into a different port (preferably USB 3.0, if possible) or disconnecting other USB devices while charging.

It’s worth noting that some motherboard manufacturers—such as Gigabyte—have begun incorporating high-powered USB ports that can deliver up to 2.7A of current onto their boards. If you want to rapidly charge devices while they’re connected to your system, it may be worth checking out one of these boards.

Problem: USB Device Is Not Recognized

Solution: USB devices are usually as plug-and-play as you can get, but if a particular device isn’t recognized properly, it may be incompatible with your USB controller or require drivers to be manually installed. Compatibility is very good with USB controllers native to modern chipsets, but we’ve seen some incompatibilities with some discrete USB 3.0 controllers that are yet to be resolved. Should you need to install drivers for the device, plug it into a USB port, then go to Device Manager, right-click the device, and choose Update Drive Software from the menu. Then, you can search the web for drivers automatically or point the wizard to any drivers downloaded from the device manufacturer’s website.

Methods used for the calculation of areas in Surveying

Methods used for the calculation of areas in Surveying: Simpson’s rule Trapezoidal rule Graphical rule Simpson’s Rule Statement It states that, sum of first and last ordinates has to be done. Add twice the sum of remaining odd ordinates and four times the sum of remaining even ordinates. Multiply to this total sum by 1/3 rd of the common distance between the ordinates which gives the required area. Where O 1 , O 2 , O 3 , …. O n are the lengths of the ordinates x = common distance n = number of divisions Note: This rule is applicable only if ordinates are odd, i.e. even number of divisions. If the number of ordinates are even, the area of last division maybe calculated separated and added to the result obtained by applying Simpson’s rule to two remaining ordinates. Even if first or last ordinate happens to be zero, they are not to be omitted from Simpson’s rule. The following offsets are taken from a chain line to an irregular boundary toward...

File attributes and NTFS permissions

Chapter 5 - File attributes and NTFS permissions   We’ve already mentioned both file attributes and NTFS permissions throughout this book. In this chapter we’ll take a closer look at file attributes, and discuss how to view and change attributes from the command line. We’ll also examine NTFS permissions, which are considerably more powerful than file attributes, and discuss how to view and alter them as well.   WHAT ARE FILE ATTRIBUTES?   “File attributes” are basically pieces of metadata that contain additional information about the file. In Windows, files generally have their names, their types (defined by the file’s extension), and their timestamps. (Certain kinds of files, such as MP3 music files, have additional kinds of metadata, such as the album and artist name.) With file attributes, however, there are four additional pieces of information that you can add to a file.  These four pieces of information are: -Archive,...

Construction of lead acid battery

Overview of lead acid battery It is the main overview of lead acid battery,working and construction. In lead acid battery there is a group of cells and in each cell there is one group of positive plates and one group of positive plates and one group of negative plates. The positive plates are made of lead peroxide (PbO2) and negative plate is made of spongy lead. Thus for identification the positive plate as the color of dark brown, whereas the negative plate as the color of light salty, Construction of lead acid battery In this topic we are discussing about the lead acid battery working , and construction . mainly construction you can watch the video  Main parts of lead acid battery 1. Separator. It is most important part of lead acid battery. Which separate the positive and negative plates from each other and prevents the short circuit? The separators must be porous so that the electrolyte may circulate between the plates . The separators must have...
