U2415, USB HUB does not work as usual?

Hi all

Today afternoon I noticed my printer disappeared from my operating system... After some tests, I realized that the question at issue also all other devices that I use to keep connected to the monitor usb hub.

This morning, I left the PC after turning off the screen by pressing the power button, I use to do when I go for dinner... But usually when I come back in the afternoon and I turn on the monitor, all connected devices are displayed correctly and work as expected (printer included).

This time, something went wrong. I also suspect that maybe I hit a place hurt when I press the button works stop because I was in a hurry...

Could I have disabled somehow the hub... What do I do or where I could check it?

Hope that it is not broken.

Thanks in advance!

"turn off the monitor.

Who did the trick!

When I restarted my PC after you unplug all devices, I have not turned off the monitor.

Now, I'm just trying to turn the monitor off and then back on. Finally, I inserted the usbkey and check out of "lsusb".

Look at!

Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

OK, the monitor hub seems to be indicated as "Texas Instruments, Inc. TUSB8041 4 - Port Hub. And you can also see the USB "datatraveler".

Seems everything is for the best... In any case, very strange question...

Thanks a lot for your support!

Sometimes the solutions are the simplest... :)

    Can you please hellp me to install it? I have download the drivers from Toshiba for my NB200

    If everything is OK and right drivers all USB ports should work. You cannot install the drivers for each port separately and force one of them to work properly. On this machine, all three ports are the same USB2.0 ports.

    Try reinstalling the chipset utility.

    By the way: two other ports work well, right?

    Hello

    > This problem start after a storm in my area some time ago.

    Because other devices don't work properly and because procedure didn t get it back help you solve this problem, I think that the problem is related to the hardware malfunction possibly that the motherboard was hit by lightning, which would explain the problems

    I think you should ask the maintainer authorized Toshiba in your country to check the motherboard.

    But in my opinion, that the warranty does not cover the issues of environmental impact maybe your household insurance could help you

    The USB port does not work with other USB devices?

    I suspect an incompatibility with the EC and the sine of dongle USB EL strengthened using third kexts. They must be signed, and so a softer update for the dongle is probably necessary.

  • A 'Powered USB Port' does not work on Mac Mini

    I have an external POWERED USB multiport block. When I plug the Superdrive into a Port powered on the unit, which of course is connected to my Mac Mini (2012) the Superdrive not even she acts as if it is connected and will not accept a disc. All ports are USB 3.0. I'm so uncertain that the Superdrive will work on any USB port other than the one on the Mac itself. Any advice? I El Capitan installed, but it has worked that way before the upgrade.

  • My usb port does not work. Device Manager says he has a "code 10".

    My dad recently bought a laptop on ebay. It's a HP Omnibook 900 with a 4 GB HD. The previous owner had improved from the original from Windows 98 to XP with SP3.

    It has a USB port in the back & it does not work!

    In fact it is not even appear in the Device Manager! I need to select 'Show hidden devices' to see same the USB hub root. The USB port has a yellow warning icon. In properties, it indicates the port is enabled but does not work because of a "Code 10".

    What the devil is a "code 10" & how in the heck to solve this problem, so that the USB works?

    The port is powered. When I connect devices usb load they turn on & load, but, of course, are not displayed on the computer. My best theory is that the port can be usb 1.0 but the software is intended for usb 2.0 and what could be the cause of the problem. That's just guessing on my part because I do not know with certainty if the usb is 1.0 or 2.0.

    It is especialy boring being the only external devices can I plug a CD player (unwritten) & a floppy drive. It would make my life much more pleasant if I could run software, backup & file transfer, etc. with a usb drive instead! It could even than the laptop quite useful to be worth the bucks thirties, my father paid for it!

    Help, please. Thank you.

    Hi SnarFoo,

    Method1

    The Code 10 error code is generated when Device Manager it has not enough information or error that has spread upward through the device drivers is not recognised by the Device Manager. In addition, this error may occur if one of the pilots who needs the unit does not start. If multiple drivers are used by a particular device, it can be difficult to determine which failed.

    See the article and check if that helps.

    Description of errors related to the 10 Code that generates the Device Manager in Windows on computers

    http://support.Microsoft.com/kb/943104

    Method 2

    If the previous step fails, then remove and reinstall all USB controllers on the computer and check if that helps.

    To remove and reinstall all USB controllers, follow these steps:

    (a) click Start, click run, type sysdm.cpl in the Open box, and then click OK.

    (b) click on the hardware tab.

    (c) click the Device Manager button.

    (d) expand Bus USB controllers.

    (e) right click on each device under the Bus USB controllers node and then click Uninstall to remove them one at a time.

    (f) restart the computer and reinstall the USB controllers.

    (g) connect the removable USB storage device and perform a test to ensure that the problem is solved.

  • Portege 7220CTe he's - USB dock does not work properly

    I have a portege 7220, with Dock he's using windows 98se.
    I have 2 usb ports on the dock, one that I use for mouse, 2nd I use for hard disk USB, cards memory sticks etc. When I start with 2 installed, often they will not work. Installing after startup does not work either. MILADI repairman told me to bring pc + dock in because they think it's a hardware problem. But sometimes, the usb works with 2 installed users. Who can help me? BIOS (ACPI version 1.70, 29/09/00).

    Hi Buk

    Trust me on this path is not easy what's happening with your USB ports.
    Do you have similar problems if you use the USB ports on Portege itself?

    As you know the signal USB is just loop through and there may be a problem with the circuit of the port replicator.

    I really put t think you will be able to solve alone.

    Good luck!

    Hi Gerold,

    It looks like a hardware problem with your USB port. Visually check the ports that do not work and you should see a central plastic ankle against which should be four strips of copper fitting. Make sure that none of the tapes is twisted or damaged, it is quite common for one or several of them have been accidentally bent out of position or ankle Central plastic must be broken.

    Kind regards
