Check the USB connection
The icon on the USB cable (c01424575.gif ) faces up when the cable connects to the product correctly. Check the back of your product and the back of your computer to make sure the USB cable connects correctly and securely.
After you make sure the USB cable connects correctly and securely, review the following guidelines to check other potential USB-related problems:

  • USB ports on the keyboard. USB ports on the keyboard and in the front of some computers might not be powerful enough to support the product. If the USB cable connects to the USB port on the keyboard, try connecting it to another available USB port on the computer.
  • USB cable length. HP supports USB cables less than 5 m (16 feet, 5 inches) long. However, a USB cable that is 5 m (16 feet 5 inches) long must be of high quality. Otherwise, HP recommends using a USB cable that is less than 2 m (3 feet, 3 inches). Do not use patch cables to increase the length of an existing cable. Use a powered USB hub if you need more length.
  • Alternate USB ports. Connect the USB cable to another port on the computer to make sure that the USB port on the computer is not the cause of the problem.
  • Defective USB cable. Replace the USB cable to make sure that the existing cable is not defective.
  • Conflicting USB ports. Disconnect any other USB printers, USB scanners, USB cameras, and any other USB connected peripherals. Start reconnecting these devices one at a time to determine if one of the devices is using too much power. Consider purchasing and installing a powered USB hub if necessary. NOTE: A USB-powered hub is a device that increases the number of available USB ports on a computer and facilitates communication between the USB devices and the computer. A powered USB hub can resolve communication failures between some, but not all, USB chipsets and HP products.

My laptop XP is not detecting Transcend StoreJet 25 External HD 500GB, but in desktop XP it is very well detecting and working. Pls let me know the solution for my laptop


USB devices draw electrical power through the USB cable.

Sometimes, the power-output from a USB port on a laptop is _less_ than that of a USB port on a desktop computer.

Hence, there are "Y" cables -- connect to two USB ports on your computer, and to the USB device at the other end, to draw more current.

Which manufacturer of laptop?
Which model-number?
Which Operating System?
Do other USB devices work when connected to the laptop's USB ports?

Clevo m745s laptop no audio device detected


Hello...
Full details about sound issue in my website...
www.sureshayyar.110mb.com (Support page)

As an alternative u can do this (i am using this solution till date)

If u cant install the sound driver correctly, just buy a " USB Sound Adaptor" and connect it to the USB port and connect the speaker sound jack to the sound port in this adaptor....u will get back the sound....also keep in mind that u " may " have to disable onboard sound in BIOS, u may also have to make changes in the Control Panel / Sound and Audio Devices / Audio Tab / Sound Playback option... Click the drop down button and select the "USB Audio Devices/Headset"

You can get it in Ebay for $1 to $4 or google it to locate a place near u......

This is the one i am refering to(I bought it in Ebay for 1$)....u can buy something similar also....there are many available mfd from China, just plug and play on your USB port....

If you find this solution useful please leave a feedback and rating to this solution.

Regards....
All the best, my dear friend....0c2f2b6.jpg

Usb ports no communication with compurter but supplies power. what is wrong ?


Click Start
Click Control Panel
Click Classic View
Click System
Click Hardware
Click Device Manager

Does the 'USB' branch of the tree show the USB ports?
Is there an 'Unknown Devices' branch of the tree?

Either way, the software "device-drivers" for the USB ports are not installed, or not installed correctly, and so you'll get the symptoms that you've observed -- power without device-recognition.

Access http://support.dell.com and click "Detect My Computer", and download and install the device-drivers for the USB ports.

Cannot detect device


Connect the phone while the computer is off. Power on teh computer and it should detect a new USB hardware device. You should then see two new drive designations. 1 for the phone's memory and teh 2nd for the onboard memory card if you have one installed. Remember for the first connection the computer must be off when you connect the phone.

My Lan connection will not work


It sounds like the LAN port is bad. If it is an onboard port, just add an ethernet NIC card into an available PCI slot and disable the onboard port. That will solve your problem.

When I plug in my Zen Micro to the PC to chage all i get is the flashing charge signal but the devices does not recgharge. This is the same USB that i have used successfully on another PC. it also wont...


I use to have that little player and i remember how it could be tricky on different computers.

from http://www.anythingbutipod.com/forum/showthread.php?t=27711

If these don't work please report back:
4. If the Zen is not detected by or charging from the computer when connected, make sure you are using a USB port on the back of the computer (built into the motherboard) instead of one wired to the case (front or side). That way you are using a USB port with the proper power output.

5. If the Zen is not detected by or charging from the computer when connected, make sure the USB port you are using are USB 2.0 and not v1.1. If you computer is a newer computer, this shouldn't be a problem, but if it is an older computer, it may only have USB 1.1 ports which doesn't output enough power as USB 2.0 ports.

6. If the Zen is not detected by or charging from the computer when connected, make sure you have no other USB devices plugged into the computer (front and back ports), but the Zen. That may be worth a try to see if you can get enough current from the USB ports to begin charging it again. Usually the more devices you have plugged into the USB ports, the less current that will be available for charging due to the power being shared with all other devices plugged in.

7. If the Zen is not detected by or charging from the computer when connected, make sure that the drivers are loading for it properly under Device Manager (no conflicts showing). I believe the Zen will not be detected or begin charging unless its drivers are loaded and working properly.

USB powerloss?


As you have already stated that the port in question can run a standard optical mouse, the port seems to be working fine.

Sometimes the drivers for a USB device need to be installed for each USB port. Maybe you have installed these drivers for 3 of your 4 USB ports, but not for the one in question, result of which is the problem you face.
