Portege R600-140: message says: device would work better with USB 2.0

R600-140 win 7 prof
I plug in a device of capture usb video and a popup appears saying (roughly)

+ This device would work better with USB 2.0 - Click here for a list of usb ports.

I thought all the usb ports 2.
I just checked the drivers in the Panel, and I thought they are all up to date.


The laptop supports without a doubt USB 2.0 ports.
I guess that this message can appear for many reasons: for example the USB device malfunction.
Also the problem of USB port could be responsible for such error.

So as the first workaround I recommend you remove the USB hubs and controllers in the Device Manager list.
Open the Device Manager, look for the controllers and USB hubs and uninstall the driver.
Reboot the laptop

Usually the system will begin to recognize USB devices.

Note: during this procedure, all external USB devices must be disconencted

  • HP pavilion p6777c: what upgrades would work better with my system

    I have a Hp Pavilion p6777c and I love the update for my children and a woman who plays world of warships, world of tanks and of second life what hardware upgrades can I do and stay within my budget of less than 400 dollars?

    Indy76, welcome to the forum.

    The processor is good.  I do not recommend change.  You can add more memory.  This is recommended by Crucial memory memory .  In addition, if you want to increase the speed, a new SSD better.  The essential link, he recommends SSD.  The MX200, 250 GB, SSD for $99 would be very good.  There is a guide for upgrading to a 2.5 "SSD in to the lower left corner of the page.  You would need an adapter to install a 2.5 SSD "in a 3.5 drive Bay".  If Crucial recommends they guarantee that it will work.

    If you upgrade the video card, you will also need to upgrade the power supply (PSU).  The most recent video cards require UEFI in the motherboard instead of a standard BIOS.  HP didn't start using UEFI until mid-October 2012.  The last series of video cards that does not need UEFI was the GT of the 640.  If you like the card, I recommend that you contact EVGA Tech Support (1-800-880-3842) in order to ensure that it will work on your computer.

    I love Of the PSU from Corsair.  I recommend at least 500W.  It would give you some excess power for maximum use.  The one in the link is modular.  It allows you to use only the necessary cables for a better air circulation.

  • I can't download the new iTunes update, the error message say "is there a problem with this Windows Installer package."

    I can't download the new itunes update.  Error message says "there is a problem with this Windows Installer package.  A program required for this install to complete could not be run.  Contact your supplier of staff or the package of support ".
    I was running itunes perfectly well before trying to download this update.  ITunes is not yet available.

    Thanks for your help.  Unfortunately no idea worked.  Windows Installer 4.5 is not good for Windows 7.  However, I was able to restore my computer to an earlier date and the previous itunes was there.  It still would not allow me to access without security clearance, but I finally understood how to afford access - I am the administrator and the only user - go figure!

  • A DesignJet 1055 CM c6075a would work OK with Mac OS 10.7 (Lion) or 10.8 superior?

    A DesignJet 1055 CM (model A, c6075a) would work OK with Mac OS 10.7 (Lion) or 10.8 superior?  I don't have a Mac; I plead for a potential buyer of my 1055CM. The 1055CM currently has 96 MB of RAM; I could put 128 MB in.

    I would get "out of memory" problems?  I think that maybe there is no "computer in process" option in the Mac OS 10.7 for the 1055CM pilot, but I'm not 100% on that.

    I guess it depends on how simple designs are. The application is for printing large topic say 24 "x 24" vinyl stickers vinyl roll.  Well, maybe raises another question: would a 1055CM, printing on vinyl OK?; I guess because they seem to be very similar architecture/configuration as a 5000 or 5500 and these OK printing on vinyl.

    Thanks a bunch.


    Hi Paul

    I wouldn't say a 1055 for work of vinyl. There are a few suppliers who can provide a vinyl fot this printer, but it's not too successful.

    First ink 1050 won't last long, it will fade fade very quickly. (you can use a laminate liuid, but time consuming, will not worht it.)

    Secondly, the 5000 series printers have a different ink, it means the UV ink and ink to dye. Two inks are specialised in the printing of "vinyl" or "post".

    Your best bet is to get a HP designjet with Viera of ink, with the correct paper, that they have to use intermediary.

    Otherwise a second hand series Z (Z2100 going quite cheap, comes in a cheaper A1) these printers have pigmented ink which have a longer life of the door.

    You can post on the Pr material forum for views on your listing and if there is no mercury potential engine of reading problems, but I would say that you really want to know how Pr will respond by installing on your machine (maybe setting a restore / restore, first if Mac offers that). You are the best solution would be to download a free trial version of Pr CC 2015 to give it a test run. Don't know what your needs / budget are, but since Adobe works by monthly subscription, you can also download the full Suite of Cloud Creative at trial. Then you will get After Effects and hearing that link dynamically with Pr play with as well (and Photoshop, Illustrator, etc.)

  • Portege R600-10 q - Touchpad no longer works


    My touchpad has stopped working. I tried to turn on and off with the FN keys and this did not help - can someone let me know what I can do to get it working?



    Maybe you should put the exact cell model and the OS you are using.
    What do you think about this?

    In any case, what happens if you connect an external mouse? Can you work with it?

    What is the other FN keys work? Perhaps only the utility ON / OFF touchpad isn t work and can be solved with a new installation.
    In addition, you must update the driver for the touchpad.

    Good luck!

  • Not found DVD Maker "DVD burner" message when DVD writer works well with other programs


    I just created a DVD with AVS Video Converter and burned a DVD with no problems and created later a film with Windown Movie Maker, which worked well, it has exported to Windows DVD Maker, again not a problem, but when I click on burn, I get a not found message "DVD burner". How can I fix, I know the burner works very well because it works with other programs... And Windows DVD Maker was working fine until recently and outside a updated Windows Vista, I did not further updated or changes to the computer.

    Thanks for your help!

    Hi Froggie_UK,

    Since this problem you encounter began after that windows update, you can use the System Restore tool to return your computer to an earlier point in time. The tool using System Restore may not necessarily help you determine the problem. When you use system restore to restore the computer to a previous state, the programs and updates that you have installed are removed.

    Before you start Please back up your data

    To restore the operating system to an earlier point in time, follow these steps:

    ·         Click Start, type System Restore in the search box, and then click System Restore in the list programs. If you are prompted for an administrator password or a confirmation, type your password or click on continue.

    ·         In the System Restore dialog box, click choose a different restore point, and then click on Next.

    ·         In the list of restore points, click a restore point created before you started having the problem, and then click Next.

    ·         Click Finish.

    ·         The computer restarts and system files and settings are back to the State they were in when the restore point was created.

    If it is an update, the best way to solve this problem is to apply only updates one at a time to determine which updates is causing this problem.

    Click on start-> all programs-> Windows Update, click on change settings in the left menu. Select download updates but let me choose whether to install them, click OK. When you are alerted to install a new update, in this window, click updates see, uncheck all updates and select one at a time, install it, restart your computer, test and update. Once you find the update either continue to ignore it, or look for it at http://support.microsoft.com/.

    We hope this resolves the issue and look forward to hearing back from you on your results.

  • Message saying I have a printer (with driver numbers) that I am not.

    My printer does not print. I've checked everything and the only problem now is this: hardware and peripheral slot a message appears saying that I have several different driver with a Lexmark A422 problems.  I don't own a Lexmark A422.  The printer that I am using is a HP Officejet 4500 Mr. this never used to happen. At the same time I installed Windows 10. I didn't like it, and I thought that it had been uninstalled and installed Windows Seven. I wonder if the Windows 10 had something to do with this printer problem. In addition, I am harassed by frequent popups telling me to upgrade to Windows 10... (again and again and again!) Does anyone have a suggestion?


    You can stop Windows 10 harass you or install automatically - see upgrade to disable Windows 10 - WiKi


  • What bluetooth earpiece for people work better with the iPhone (6)?

    I am currently using an iPhone 6.  Have you tried a couple of bluetooth headset, but have had some problems. The Motorola I redials the last number, I called instead of start Siri when I push the button. Does anyone have recommendations? Thank you!

    To be honest, it's really preferences. You would have to research which devices are supported, Siri, if that's important to you. I know that my blue Ant T3, and it also stores my contacts list. This means that when the phone rings, the unit actually announces the caller's name, and I can give a voice command to answer if my hands are not free.
