• Windows 8 recognizes not all USB ports

  Everything I plug my usb ports is not detected. All my USB drivers say this: the software for this device has been blocked from starting because it is known to have problems with Windows. Contact the supplier of material for a new driver. (Code 48)

  Click on 'Search for solutions' to send data about this device to Microsoft and to see if there is a solution available.
  Seeking solutions does nothing. Any suggestions?

  OK GUYS - HERE'S THE ANSWER:

  For starters, I had the exact problem as OP. I upgraded my windows 7 to Windows 8, about 2 weeks ago, and all of a sudden all 8 of my USB does not work.

  I had MS Answerdesk Diagnostics TWICE to try to solve this problem, the last time they said that their agents of level 2 had to work on the computer (but never called).

  After looking online for the past 2 WEEKS and no answer final as to really solve this problem, CKnospe option actually worked, but I had to do one thing first:

  I was going to install and uninstall the program to see if there is nothing, since HAVE charger didn't appear on the list of population programmes.

  There were 3 options after I unpacked and loaded Setup program. Repair, installation and the bottom option was 'DELETE '.

  I chose to delete, as I didn't even know the program was on my computer (doesn't appear on the list of population programmes) and he forced a restart.

  After the reboot: BOOM, my USB FUNCTION.

  Hope that anyone looking for an answer to this tent I've done. I can't express how I am happy with this easy as pie. Seriously joygasm here.

  Peace.

• 8460w some (not all) USB ports not working not

  8460w running Windows 7 x 64.

  2 USB ports on to the left of the computer (facing it) do not sign anything when you plug something.  All other ports seem to be in perfect working condition.

  -Updated all the USB drivers

  -Confirmed that nothing is turned off in the BIOS

  -Uninstalled all drivers USB, stop, removed all forms of power, held the power for 1 minute and let stand for 20 minutes

  -HDD Ran, start-up and break-in of diagnostic tests

  -Replacement motherboard

  -Repeat everything with the new motherboard

  There is no windows error, no bubble popup in the system tray and no problems in the system logs.

  Literally my mind stops there.  Can anyone think of anything anyone else I can try?  Any ideas AT ALL would be great.

  Thank you.

  Workaround.

  There was a missing element that was supposed to be bundled with the Systemboards.  It's a small daughter card that inserts directly behind the USB 3.0 ports.  Once I found on another computer, I was able to use it in this machine.  Thank you for your time.

  Troubleshoot failures to find the new LifeCam hardware

  I hope this helps.

• plotter / cut not the usb ports

  I recently moved my office and cutting cutter / plotter in another room. Now, for some reason, my vinyl cutting software does recognize not all USB Com Ports and therefore, will not cut.  (I tried configuring it for each port with no luck). When I open devices and printers and look at USB / series of properties of Strawberry, it shows that its on Com9... and I have 6 USB ports I know.  First question... where I expect to identify the USB ports are what #s.  4 behind the pc and 2 in front.

  Com is a reference to the COM port and is a "serial port".  Replace the USB port.

  PS <>, change the hardware configuration does not cause this problem.   Someone changed the settings.

  I'm sorry that you are experiencing this issue. Try connecting the 8600 USB in another USB port. You plug it into the USB 3.0. If you have plugged it on the left side of the computer, try on the right side.

  Let me know what happens.

• All USB ports stopped working Windows 7

  Windows 7 Pro. All USB ports stopped working.  When I plug a usb card, windows makes the sound as it connects and the card gets power (light).  I see the map appear in disk drives in Device Manager.  The player does not display in windows Explorer or disk management.  In Device Manager, it has an exclamation point and says that the device cannot start.

  Strangely, I have a USB keyboard and mouse and they work very well.

  It's just the USB drives and chips and SD cards that are not displayed.

  I have:

  Reinstalled the drivers USB MB

  Flashed the BIOS with the latest version

  Tried to install the older USB drivers

  Tried to let windows find the driver.

  Still does not

  None of this has helped.  I ended up formatting the HD and reinstall windows from dvd.

  This revealed that my USB multicard reader was bad.  When I unplugged the problem disappeared.

• HP K5H28AA #ABL: accidentally disable all usb port

  Looking to change the settings in my BIOS I accidentally disable all USB ports. Now I can't use the keyboard and mouse. I want to know if there is a way to reset to the factory settings, the computer from the motherboard

  Hello

  Before you try this, unplug the devices all attached, turn off the PC and remove the power plug.

  There should be a jumper on the Board that you can use to remove the settings current CMOS, located just above the cmos battery - move the jumper to the clear position for 30 seconds and then bring him back - see the image at the link below.

• Satellite C50-A-138 - all USB ports do not have

  Hello

  I have a major problem with my Satellite C50-A-138.
  The card reader has never worked, and one by one the USB ports have stopped working.
  I can connect my phone to each of them, and he will.

  But I can not plug any device into the port and have the laptop recognize at all.
  So far, I tried the following:

  Deactivation and activation of each port
  Uninstalling and reinstalling
  Updates
  Updating of windows 8
  Reinstallation of windows 8
  Regedit HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\UsbFlags
  Regedit HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\usbhub
  Download of patches

  Is there anything else I can do to make them work again?

  > Card reader has never worked, and one by one the USB ports have stopped working.
  It is really strange. This model laptop was offered with Win8 64-bit and I can't imagine that a few pots do not work on the first day, and from the moment when the laptop was delivered with factory settings.
  > Reinstallation of windows 8
  Have you created a recovery media and then installed recovery image using this media?
  With other words, have you tested the feature with the factory settings?

• Device not recognized USB error message - all USB ports.

  Apologies if all this seems a bit simple, but I'm not an expert, so bear with me.

  I have a laptop Fujitsu Siemens Amilo Li 1718.

  My USB ports have stopped working in 2-3 weeks.  I get the message "USB device not recognized.  One of the devices attached to this computer has malfunctioned and Windows does not recognize... »

  I don't seem to get any yellow exclamation point in device, all my drivers in Device Manager and software are up to date and Windows Update is running.

  My mobile phone and ipod always charge when I plug them in and out of this problem, everything works fine.

  In addition to the usual updates of Windows, only two other things have occurred since last, they worked.  One was that I renewed my subscription to Norton Antivirus, the other was that my laptop battery ran right out while he was in mode 'sleep' as I did not know that I had not plugged to the socket properly.

  So far, I went through some process as suggested by various items and/or help & support on Microsoft.com.  They include:

  * (From multiple locations) system restore has failed.
  * Diagnostic software Ran Fujitsu Siemens, which says that my computer is fine.
  * Run the virus scan who come clean.
  * Tries to connect via a USB hub.
  * Deletied the USB controllers in Device Manager to re - install.
  * Changing the settings of ForceHcResetOnResume 3-to-1
  * Change AdditionalCriticalWorkerThreads from 0 to 2

  (The last two I've changed back again after neither worked).

  My opinion of beginner, it's that looks like it will create new registry details for each device when valid seem to exist already is not thankful.  Although given my lack of technical knowledge, this could well be stating the obvious.

  So, now, I drew a blank.  Anyone got any ideas?  Got 9 months left a 3-year warranty, I don't want to go through the hassle if it can be avoided without too much trouble.

  Thanks in advance!

  Have you tried to use an external hub powered by USB power is very limited in a computer and if overloaded
  strange problems will come up.

  ------------------------------------------

  Even if you did some of this departure please up and work until low and if necessary check
  with the utility.

  Control Panel - Device Manager - click in the empty area - VIEW - show hidden devices

  Now look everywhere EXCEPT the USB controllers for your device (cannot be found) and if you find
  It RIGHT CLICK and UNINSTALL all. The device is your (s) or similar.

  now go to the USB and UNINSTALL ALL controllers in the category, but the category itself.

  APPLY/OK

  RESET

  This refresh battery USB and hopefully it will allow the unit to install. (You may need a powered hub)

  Here is the similar procedure under XP, Vista is the same, except that we need to clear the specific device if present.
  http://support.Microsoft.com/kb/310575

  This is a utility to help you, but do 1 above.

  USBDeview is a small utility that lists all USB devices currently connected to your computer, as well as all
  USB devices that you previously used. Run Options and check the 1st three choices to see if one is there.
  Try to remove all instances and restart then plug the drive.

• Satellite is not printer - USB hubs all permits

  I have a friend with a laptop satellite, and she tries to make him talk on his printer. The computer sees the printer, but apparently he is not talking. We checked all USB root hubs and show all activated.

  In addition, she's trying to network with another computer via USB. Yet once, nothing happens.

  It uses Vista on both computers (the other is non-Toshiba laptop) and we know that we have all the drivers installed correctly.

  Anyone can shed some light on this? Feel free to send me an e-mail to [email protected] if you wish.

  Thank you!!

  Hello

  You said that the laptop has recognized correctly the installed printer.
  Well, in your case I would recommend checking the settings of the printer if the preferred printer was selected as the default printer.

  Usually, you will find these settings in Control Panel-> printer settings.

  Is there anyone to show me any solution?

  Thanks in advance,
  Concerning

  Any solution? You mean a magical solution? :)

  No one knows the configuration of the laptop.
  No one knows what OS you are using.
  Nobody knows what you did last time with your laptop.
  No one knows how long you have this problem.
  No one knows what are the USB devices that you use to test USB functionality.
  What you have already tried to do about it?

  You want to have more questions?
  Maybe you should write more than three short sentences as a description of the problem.
