Put short current USB

When I plug an external device (interactive metronome - therapy neuro-cognitive/diagnostic tool) in Windows XP via Parallels, after some time (ranging from 2 ~ 30 min later) an error pop up message notification:

USB over current notice

A USB device is currently developing too much power

The hub to which it is attached to will be de-acvitated

This never used to happen.  My guy at clevertech said its likely the logic board... other ideas?

I can work around this problem by clicking NO in the dialog box context-sensitive (to disable the USB port), restart app and re - plug in the USB...

MacBookPro 15 "

2.16 Ghz IntelCore 2 Duo

4 MB L2

2 GB Mem

10.5.8

Parallels v3.0

If you use a multiple plug bus-powered hub or no hub external at all, this can happen.

You can get a good self-powered hub to $20-ish at BestBuy - power AC gives power to USB devices and the MBP has only to provide communications.

  • Put the current sim in unlocked iPhone

    Hello

    I currently have an iPhone 5 c locked to the O2 on a 24 month contract. I recently bought an iPhone 6 directly from Apple, that is to say unlocked and have ordered a contract monthly only sim which will arrive later this week. My question is, I am able to put my current O2 into the new phone sim until arrives the new sim card, or it will mess up the new phone somehow (that is to say block him on O2 or something like that)?

    Thanks for your help!

    You can safe the old SIM in the new phone. The lock status is based on the IMEI of the phone, not the SIM card.

    Hello desflo,

    Thanks for the return of the response.  First of all I suggest to go to the manufacturer's Web site and confirm that you are on the latest drivers, firmware and BIOS, updates.   Does your computer have a diagnostic test included on your laptop provided by the manufacturer?

    As you also experience this problem without using USB devices, I would suggest running the test of diagnosis or by contacting the manufacturer directly.

    Please let us know status.

  • The famous message «current usb...» blackBerry smartphones ».

    I have studied this issue and tried all the solutions I could find online and I always get the message "' current usb does not verify that your Pocket PC is connected to a powered USB charge source and that the appropriate USB driver is installed." "
    My BB is connected to my laptop usb port (I tried all four) laptop is plugged into an electrical outlet. I have installed and reinstalled the DM 4.7 3 times. The BB shows in Device Manager as SD Blackberry under "Portable devices" and says that it is working properly. The BB Desktop manager sees any unit.
    I use the 64 bit version of Vista Home premium. The laptop is new the new blackberry. Oh AND I made sure the power management for usb "allow the computer to turn off this device to save power" is deselected.
    I even tried to install just the USB and Modem driver off site of Blackberry which eventually completely wipping on the Desktop Manager and still does not work.
    So now what? I am really frustrated. It took hours to try to fix. Any ideas?

    BTW, I can charge the phone via the usb port and access to the press card, but that's all. DM doesn't connect or doesn't see the device. I can't synchronize my calendar or contacts

    Well I came across a solution, at least for me, and I'm on secondment incase someone would try it.

    I received NO indication of blackberry devices under USB controllers no Smartphone Blackberry Manager nothing. Only Blackberry SD under "Portable Device" that shows just that vista was to see the mass media card in the blackberry. DM has not seen the BB and my BB gave me infamous message mentioned in my post.

    Anyway, with the Blackberry plugged into the USB port, I did a Windows Update. Not really to think that he would do anything. Well, I was wrong... among all updates for Windows was updated for Smartphone Blackberry RIM. So I installed it and poof the computer began to install the device driver and now I'm in business! No where in my research I have see performing an update of Windows with the connected Blackberry. I don't know even why I tried, but I'm glad I did. Hope this helps others.

  • measurement of the current usb or 6009

    I'm trying to trace the evolution of a CCCV charger while it loads a 60V lithium-ion battery. I know that the charge rate is (1/6) C and the nominal capacity of the battery is 26Ahr resulting in a current of 4.33 has during this constant stage. I have the NI USB-6009 case and that e/s analog devices is estimated at 50 Ma, so I can't connect a thread of the charger directly on the device OR. I was thinking of buying a CT that connects directly to the material NOR and run the (+) lead from charger through the CT, as it charges the battery. What is the best way to go with the flow for a complete charge cycle? What are the other options to draw current developments?

    A CurrentTransformer will work with current alternative...

    A CT compensated with element Hall (research LEM) can measure AC / DC...

    I'd look for a Hall Allegro current sensor... has a galvanic isolation output, and the output is the input range 6009.

    You can see what the unit is ESTIMATED to consume.  This is not a value of actual consumption.

    It is possible to achieve this programmatically, but I doubt it will give you the information you are looking for...

  • Can I put a current 2015 DPS DPS app once it starts?

    I have a few questions about the new DPS 2015:

    (1) once DPS 2015 launch, it would be possible to take an existing application of DPS and start using the DPS 2015 for the next issue, or you have to do a new application from scratch? I have a few apps that I think that would win the new publication based on the article, but I don't want to lose the current readership in applications.

    (2) is there a library in 2015 of DPS or when you open the app are the cards, the first thing a reader sees?

    (3) how will this affect Analytics vs articles questions?

    Hi Emily,.

    It depends on how you want to manage the existing application in the store. If you want to replace your existing application and then use the folio in 2015 of DPS migration tool to migrate all your old content on, create a new application and submit this new app in the store to replace your old. Your readers will get the new DPS 2015 experience but will still be able to access the content of the former (now as collections migrate 2015 DPS, rather than slips in the old APP). This option is available for iOS to launch and will work with Android and Windows shortly after.

    (2) there are no library more. Instead, the reader sees browse pages and maps. You can decide on the structure of your application by using browse pages and maps. If you want a simple view of what you have as folios, you just build a collection that has your old numbers in there and make a page/card layout you like to display.

    (3) analytical systems are separated. The new application will be a new instance of analytics and will not have the data of your legacy in application.

    Hope this helps,

  • How can I determine my current USB ports on Windowx XP (1.1 or 2.0) size?

    I want to buy a flash drive, and I would like to know what size my USB ports.

    It is not the size, but the speed.  If you buy a USB 2.0 flash drive, it will work on USB 1.1 or USB 2.0.

    If you only have USB 1.1 ports, you will get a warning when you plug the flash drive that "this device might work more quickly if connected to a USB 2.0 port.

    To determine what you

    • Open the Device Manager (start > run > devmgmt.msc > OK)
    • Click on the + to the left of the Universal Serial Bus Controllers (it's at the bottom of the list)
    • You will see one or more lines containing the words 'Host Controller'.  If neither of these lines has the words "Enhanced Host Controller", then you have at least some USB 2.0 ports.  If none of the host controllers is "strengthened", then they are all USB 1.1
    • Some older computers have a mix of USB 2.0 and USB 1.1 ports.  If you see 'Enhanced Host Controller' in the list in Device Manager, but you get the warning message when you connect a USB 2.0 device, try another port.  In particular, if you first tried a port on the front of the computer, try one in the back instead (or vice versa).

    Hello

    You can reset the USB ports on the system and check. On a portable computer, you can remove the battery and wait 10 minutes and then plug in the battery and then turn on the laptop. This will reset the USB ports on the system.

    I suggest you to contact Fujitsu support for assistance on how to re activate the port for this specific model of laptop. Click on the link below.

  • My speakers to the stopped working. Them are the Logitech speakers to a laptop. When I turn on my laptop, I get a message that says the following. Error 0701: over-current usb on HC/Port-Bus: ooh Dev1dh Fun: 024 / Port: 01 h

    Logitech speakers no longer work on my laptop. I need help. I have windows vista home, I had these speakers for over a year and now they do not work.

    Hi Rickdm,

    This error occurs when you have a USB device or USB port problem.

    You can try to remove the speakers, restart the computer and check what is happening.

    If possible, try to connect another audio device in the computer. Try a pair of speakers to ensure that the problem is not related to the different sound device.

    Determine whether you can hear sound. If you can hear the noise, there is a problem with the audio device.

    This also happen if the usb port is damaged, try with a different usb port. If it still doesn't work do not, contact manufacturer as it is a hardware problem.

    Hope this information is useful.

  • I put the current files to the web server, but they do not show on the refreshed page.

    Again the site of another company. Must have used the older version of DW. I have CC. I synced the whole site, but when I replace an image on a page, save it and put the page and the image to the site, it does not appear on the site online... Even from a different computer. -Kenn

    There are a few things that could happen here, the most common is a redundant server root folder in your files the.

    When you set up a site in DW, it is assumed that you will move the contents of your local folder in the root folder on the server. Sometimes, people will accidentally add that htdocs, www or in public_html (or whatever we call) root server for local files and create a problem of redundancy where the site is downloaded, just for the wrong folder to be considered as a normal Web site.

    If you could open your files window, connect to the server, then hit the Expand (two squares icon in the toolbar of the window files) and post a screenshot of that here, we could exclude enough quickly. There are a few other issues, such as the capitalization of names (servers are case-sensitive so Home.html is a file separate from home.html to the server locally, they are the same file) that could happen, but it would be the first person I would check.

    The same reaction has been, as I have connected a special CUSHION cooler for laptop with additional USB Ports.
    The CUSHION cooled - but the USB Ports do not work for all devices (devices I am familiar with the)
    Ports of origin of the laptop, has failed to TRIM, too). (worked directly devices: mouse, webcam, keyboard, drive hard usb)
