• Tecra S2: HDD as unknown device on two of the three USB ports

  Hey again,
  I thought then that I was here anyway I could ask this too.
  The tecra S2 has 3 USB ports, they all work very well for my USB mouse and other small things like the wacom tablet...
  But when I plug my external hard drive in two of them, it says that it is an unknown device...

  We had once set up a pilot for a small converted Converter a series (or parallel, cant he recall) cable to the usb port
  (I have already uninstalled the drivers but nothing has changed)

  It's just a guess...

  any idea on how to solve this little problem? : p

  With the A1 facing upward, push on the left side of the tab covering the microphone port. He opens and switch upwards or downwards, and stay connected to the right side.

• Cannot use the Micro-USB port on the coming Pro 11?

  Hello

  Can I use the micro-USB port to a mouse or other device (with Dell micro-USB to USB dongle for tablets)?

  Bought one as advertised and does not work...

  Thank you

  Hey guys, it seems that there is still much confusion over the functions of the port mictousb on the place of the 11 sessions pro.

  Anyone know if it is possible to use it for anything other than recharging? An OTG cable connected I have here doen't work on my 7130, but on ebay, some sellers here in Germany offer small hubs with OTG funcion specially for this model:

  http://www.eBay.de/ITM/kwmobile-3In1-micro-USB-hub-adapter-fur-Dell-venue-11-Pro-Schwarz-Verteiler-Kit-/361194175623

  Does anyone know for sure who is the truth?

  EDIT: also, as the microusb port has the logo of bolt on I guess this is the port used for the powershare function (if this feature is enabled in the BIOS). Does this mean I have to buy a microusb to microusb cable to recharge my mobile hollow 11 meeting places powershare function?

• How to activate the monitor USB ports?

  I got my monitor connected to my surface 3 pro and I tried to plug in my phone so I am connected to the USB hub on the right side of the screen of WFP 2007 and nothing happens I have to assume I have to configure something but I don't know what.

  First of all, I doubt that the USB ports monitor downstream will provide enough power to charge the phone. Give it a shot. Second, for the monitor USB ports downstream from the function, you need the USB upstream in upstream USB port monitor. The other end plugs into a USB port on the computer.

• Tecra S11 - 15 t - modem GPRS does not work on the internal USB port

  My moden GPRS doesn't work when I plug it into the USB port of the docking station or if I use a USB port hub. If I plug it directly into the USB port of the laptop, I get an unknown device in Device Manager.

  I tried to reinstall the chipset of my Toshiba Tecra S11-15 t. I can't the device runs directly from USB port on the laptop. I have WIN XP Professional.

  Hey,.

  I n t have experience with such GPRS or UMTS modems, but you can try to remove the USB ports on the Device Manager, and then restart your laptop. After that the ports will be recognized automatically and USB drivers will be reinstalled.

  I guess you also need a driver for this USB modem so I would recommend also reinstall this driver after removing the USB ports from the Device Manager.

  Hello people.

  Two days ago, I bought a satellite m40x-129. I wanted to use a usb mouse and a drive hard usb so I had to plug the device into a a usbport on the right side of the laptop, but is does not work.
  even after reinstalling with windows xp pro (I need to connect to a primary domain controller) has not changed. I installed all the drivers of the tool-cd burned by a toshiba tool in the original installation.
  Maybe it's a hardware fault. someone else has the same problem?

  Thanks, jens

  I'll ge see my local dealer Monday ;)

• Two of the four USB ports on my laptop has suddenly stopped working!

  My laptop (HP Pavilion) has a total of 4 ports USB (two on the left side) and two on the right side all of a sudden my laptop developed this problem, two ports USB on the left side of the laptop no longer works... They didn't stop working completely, because I can still charge my phone via the ports, but they do not detect any storage device I plug into them. The other two on the right side work perfectly... I checked my mobile device manager and the defective thing only seems to me pointed out under "other devices", where the driver for 'Fresco Logic' hub USB root is not installed... it shows "the drivers for this device are not installed (Code 28)" Please, this could be the problem and where can I find the driver?

  Hello

  You are welcome!

  I am pleased that the issue is resolved. Since it works fine, I do not think you have to worry.

  However, you can check this link:

  To find the version of ports, you can consult the HP manual (specifications).

  It will be useful.

• Two of the three USB ports works only on Compaq CQ71 (Windows 7).

  Hi, I have a Compaq Presario CQ71.

  There is a USB port on the left and two on the right. The one on the left works but the two on the right are not.  An "unrecognized" message when you use one of them, but not with each other, however there is power coming from him, as when I plug a mouse to infrared light is turned on.
  Ive updated Chipset drivers and BIOS on Compaq website. I also made sure to do all the updates of Windows. Help, please! Its driving me crazy!

  Did you meet a very old thread... but... I know that with some machines, you can actually disable some ports USB in the BIOS. Take a look here and see if there's anything out there.

• Satellite U400 - two of the three USB ports are not working

  One of these 3 ports does not work correctly and the other two ports do not work.
  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.
