• Satellite Pro L10 - USB port will not recognize devices

  Hello

  I got a L10 for 18 months. Under the guarantee, I got a replacement motherboard mounted. Everything has been ok so far. A USB port will not recognize devices, a port is ok, but randomly turns off a device attached to it and comes up with the message "USB device not recognized". The third port is ok all the time.

  Any solutions or suggestions?

  I guess there is not enough power on the USB ports and external devices may not work correctly. It is not easy to say why this happens, but there may be a problem of welding.

  I recommend you contact the service again as soon as possible.

• USB ports do not recognize hardware

  I have a desktop running Windows XP and a few months ago he suddenly stopped to recognize the external hardware on 2 of the 4 USB ports.  The two other USB ports work.  Is this a software problem or could the two USB port went bad at the same time?  I plugged a USB stick in the USB work and it does not work, but the mouse I reconnect works very well.  This same USB works on another system.  I'm puzzled.

  Thanks for your help!

  If some ports work and others do not, it is most likely a hardware problem, not a Windows.

• USB ports do not recognize my mouse

  I have a Sony 64 bit computer with Vista. I had the same Logitech VX Nano mouse before but she had to be replaced. I also had computer problems and restored the whole system using the F10 key. Now my new mouse, who has just arrived, this is the same exact model I had before will not work. It is not recognized. The mouse is very well that it is simply not connecting to USB port somehow. I downloaded the new software on the site Lgitech and I'm trying to update my drivers having a pilot online, but nothing seems to work. I'm not a geek and I really need this mouse works because I work online on my computer. Any help would be really appreciated. Thank you.

  Hi cadak,

  Which of these two is the one you have?  http://www.Logitech.com/en-us/support-downloads?modelsearch=Yes&modelNumber=Nano+VX

  You may need to install the software, but also the drivers for the mouse to be recognized (or drivers can be included with the software).  Make sure you have the 64-bit versions.

  With the installed mouse and the software and drivers installed, go to start / Control Panel / Device Manager and check that the mouse look and work correctly.

  Go to start / Control Panel / mouse and check the settings to make sure that it is correctly configured to work with your computer - especially if it's a laptop with a touchscreen.  If it has a touchpad, I would update the Sony touchpad drivers to make sure that it is not the cause of the problem.

  You have another computer on which you can test the mouse to see if it works (if we exclude a faulty new mouse or a USB transmitter)?

  I hope this helps.  If no, please specify the mouse so I can read more about the installation and what is required and the appropriate procedures.  In addition, is Vista fully up to date in terms of service packs and updates after reinstalling - otherwise, please do.

  Good luck!

• Satellite Pro M70 - USB port does not recognize the device

  My Satellite Pro M70 has three USB slots, one on the left and two (vertically one above the other) at the back of the laptop.

  The top slot to USB in the back started giving problems. Sometimes, my computer can't see all that I plugged in there. But if I unplug anything - usually the printer or the mouse - the computer will usually see it then.

  What is the problem? Can do nothing about it?

  My operating system is XP. and my laptop is 4.33 year.

  Thank you.

• My iMac does not 'see' an external device into USB port?

  My iMac doesn't "see" my Galaxy S6 when I plug it into a USB port. The same thing happens when I plug my headset intercom of exploitation to a USB port. Nothing appears in the list of devices. I can see my external hard drive listed under devices. I tried different cables and all the USB ports. Both devices to load when it is connected, but they do not appear when I open the Finder. Any ideas on how I can get the Mac to recognize these external devices?

  OS X El Capitan 10.11.3 version

  Devices section of the Finder will be only peripheral with accessible storage. Open an application that interacts with the others.

• Portege Z930-118 does not recognize the external USB CD/DVD drive

  My new Z930-118, with windows 7 64 bit home, does not recognize the external CD/DVD drive when I plug it into the USB port.

  The CD/DVD device does not even appear at all in Device Manager.

  The reader is a SE-S084 Samsun and works well on another laptop.

  I already checked for the "upper_filter", "lower_filter" with the regedit, but entries are not there, so no help.

  Hello
  I m not very well how to help you.

  I found some information about this WEIRD disc and it seems that he didn't need an external power supply. Its USB bus powered so I guess around 500mA power since it is the default value provided by a USB 2.0 port.

  I don t think that there is a problem of missing software. It is a plug n play device so you need to connect it to the USB port and the system should automatically recognise.

  From my point of view of the few you try to connect the external USB ODD two ports to aid a * Y * Cableusb.
  I think the reader needs more power provided by a single USB port.

  I recently bought a laptop Lenovo B50-50 and it does not recognize my external hard drive. It's a WD elements with USB 3.0 storage device. I tried a few of the fixes recommended on other forums, but none of them work. The hard drive comes up is the list in Device Manager, and all my usb drivers are up to date. The hard drive works perfectly on other devices. Other work of readers of fine nib. Normally when the hard drive connected to the aa one device in flashing lights. This does not happen when I connect it to my laptop.

  Any help much appreciated.

  Make sure you use your laptop, 3 USB ports, not then a USB 2 port to see if one will work. If it does not power up to contact Western Digital for support.

  Good luck.

  On USB3 I can recharge the phone, but it won t recognize anything in windows
  Any help much appreciated.

  According to specification for laptop, your laptop comes with Win8 64bits.
  Using the original version of Windows preinstalled?

  All that you have done is just, but if nothing is done, maybe you should try to reinstall original recovery feature by image and test with the factory settings.

• Satellite A10 s203: USB ports does not work

  Hello! All of a sudden my usb ports do not work on my satellite sa10-s203. Tried everything (even restarted the ashes of l-top nothing happened.) Enybody can help me? Kris...

  Hello

  If the USB ports are properly recognized in device then as Quad Manager said it could be an external problem. The USB port is 500mA power. If the external device requires more power to work in this case, it of necessary to use the external power supply.

• Satellite L750 does not recognize an external microphone

  My laptop does not recognize any external audio input device plugged into the mic port.

  I have a Satellite L750 running Windows 7 with the Conexant HD Audio Smart.

  I want to record using external mixer. I am connect the output of the bureau in the 3.5 mm microphone port, but it seems that it is still just using the internal mic.

  When I go into the sound properties, under the recording tab, it is only the internal mic. There is no option for an external mic.

  I tried updating the driver for sound card, remove the card driver sound and re - install, check all the properties under sound properties, but there is no option for the external microphone.

  I tried Googling the problem but nobody seems to have a viable solution.

  Please can someone help me get the laptop to recognize an external mic.

  > I want to record using external mixer. I am connect the output of the bureau in the 3.5 mm microphone port, but it seems that it is still just using the internal microphone

  Start a test: take an external microphone, connect it to the laptop and use a Windows 7 Audio Recorder utility (can be found in all programs-> Accessories) to record an audio sample.

  Is this possible?

  I think that the microphone that appears in the control-> audio-> recording tab panel is the external microphone jack.
  You can also click right in the recording tab and must mark the options: show disconnected devices and devices to see the disabled.

• Backup Win XP does not recognize my external hard drive

  Windows XP Backup Wizard does not recognize my external hard drive and does not list it as an option for storing backups.  I suspect a registry problem because the backup wizard previously recognized this drive and saved on it several times before I was running ARO 2012 for cleaning the registry errors.  I can always open the player in windows Explorer and see the files it contains, but Explorer Windows XP now lists the drive as an "expansion disc" instead of a 'removable disk '.  When I right click in windows Explorer and open 'properties' for this drive, it shows it as a 'local disk' instead of a 'removable disk '.  The drive is ok when I click the button 'Remove hardware safely', and it reports "safe to remove hardware" after I click on "USB storage device - Drive (J :). ».  Help!

  Who did.  Thank you!  Now... I used Aero2012 to clean up the errors in my registry that's because my computer is desperately slow, especially when you start (8-10 minutes) and also with internet explore (move cursor to previous typos when you compose a new e-mail message).  Is there a safe way for me to speed up my computer?
