Re: usb won't work

Hi, its because the usb ports have not enough power to, power on the device completely. Can you comfirm the unrecognized devices are plugged directly into the laptop and not into a usb hub, also if you go into control panel and into device manager, look up the Universal Serial Bus Controllers, Go into USB ROOT Hub for each one and into properties for them, Power Management and make sure there are no ticks.

Have a nice christmas

My usb ports on my laptop only recognizes my phone and mp3 player and not my external hdd, it tells me to format the plug and play external hdd. It does not do this in all my usb ports though

Maybe the external hard drive is to large to be recognized by your computer. Some computers won't recognize real large external drives.

Another problem could be that your external hard drive does not support Windows 7.

My HP DV9740Us entertainment laptop will only recognize one external hard drive at a time! If i plug in another via usb it won't pick it up in My computer but the computer makes the sound as if it did...

If these drives are internally powered by the USB hub, two devices will not be recognised. ie: you can have as many pendrives as you like and they will be seen, because they draw little power from the hub, however, a larger external hard drive requires more power (some of these in fact have two usb connectors to power them). which is why your laptop will only recognise one drive at a time:

Solution: If you can get an externally powered usb drive, this should work.Another and possibly cheaper way would be to get an externally powered USB hub, which would solve the problem

you may have to assign a letter to the unseen drive manually: goto start menu and right click on my computer/ select manage/ select storage/ select disk management/ right click on the drive in question and select change drive letter and paths/ then give it an unassigned letter and that should do it. hope this helps:)

My Toshiba Satellite 2805 S301 USB 1 port, does not recognize my Passport external Hard disk drive. What can I do to solve this problem ? Thank you, very much for your assistance.


assuming that the external hard disk is usb

i would try this

plug in the external hard drive
then go to device manager
then hover your mouse at the top of the box
and look for a icon that says scan for new hardware
then hit the scan icon
your laptop may or maynot recognize the external hard drive at this stage
now leaving it plugged in restart the laptop
and with any luck windows will now recognize it

good luck
hope you get sorted with it

When my friend turns on his computer on the screen it automatic says the "No bootable device" what could i do to fix it

THis error comes when your hard drive not recognized in bios.
For that make sure your hard drive is detected in bios.
When you power up the computer press F1 or F2 or "del" key to enter in bios.
Then disable SATA option in Ide configuration .
Then save and exit.
Then If still not detected in bios then you need to reattch hard drive in to laptop.
For that you need to open back cover of laptop the reattach hard drive.
Let me know if you need further assistance.
Thanks for using FixYa.

USB Problem

hmmm external hard drive should work without any problem as windows xp allready have inbuilt drivers for mass-storage.

try to Uninstall the USB driver, goto Device manager and Uninstall USB, then reboot to clean system registry and install USB driver from Windows XP setup disck. and try the external-hard drive, xp should recognize your external-hard drive. If not then install driver for your drive if you have and try. for camera and ipos u need to install drivers and supporting softwares from your manufacturers.
