• My LaserJetPro 400 printer is not recognized on the USB ports. With the help of El Capitan OSx

  Since I installed OSx El Capitan, I had intermittent problems with the USB ports to connect to my HP LaserJet printer. I first thought that the older printer was not compatible with the new OSx software, so I've just upgraded to a new HP LaserJet Pro 400 M451dw. same results and the computer is not even connect to the printer. The number of post detailing a similar problem, I would hope that apple now had a fix for this problem...

  It gets very frustrating to say the least.

• HP Officejet Pro 8500 has 910 a, Vista 32-bit, does not connect via the usb port on my PC!

  I used to have it all in one connected to my pc, until I lived some printing problems, so I decided to uninstall it!  When I tried to reinstall, the pc will not connect it.  I tried different ports and have replaced the cable, have also downloaded the latest software and drivers all to nothing does not.  I can connect wireless to my laptop, but unfortunately is not a solution for my office because it is not wireless, so it must be connected via USB.  At my wit's end, please help me!

  Hello

  Can you try to insert a flash drive into one of the USB ports on the printer, to make sure she reads it?

  The printer port may be what gives you the question. In addition, you can try the USB printer connected to another PC?

  Let me know the results.

• NEX - 5N, unrecognized by the USB Ports of the computer

  I have a laptop Asus UH56e which became more and more incompatible with my NEX - 5N. Is not what USB port, I plug the NEX in, or what USB port in my 4 ports USB hub, I plug in, the camera is not recognized by Windows 7. I try to install the new update of firmware and can't even get past the first step, which is the connection to the computer. Is there anywhere I can download the driver for the NEX - 5N install on my laptop? It seems that the driver is not install from the camera, or is not recognized by Windows 7 (64-bit).

  Yes, it shows USB MTP Mode, but it does not connect to Mass Storage. By clicking import images and videos results in no new pictures or videos found on this device, despite the fact that there are pictures in the camera. Click Browse files and media then, however, shows the folder and clicking on that, I can see the image files and copy them to a folder on my hard drive. Yes, I tried to update the firmware several times, but because the camera is not recognized by the USB ports, the camera is not found by the firware update, either. Yes, I unplugged the USB hub and all other devices and also makes no difference. I don't have another USB cable, however. I have access to another PC Thursday, so I'll check then. Thank you, Glenn.

• WiFi radio adapter off, the USB ports does not and the Bluetooth adapter is no longer visible... Please help!

  I had my laptop Dell Vostro repaired under insurance in January 2013 after a spill of liquid.  HAAC Ltd. has replaced most of the laptop - but the return, the SD card did not work.  This seems to be due to the engineer he connects not properly and the company recommended it and returned it to me again.  A couple of months, I found my USB was temperamental - so is my built in Bluetooth adapter.   Last month - the wifi does not work for most of the time either so I have to connect to my router by wire.

  This could be a problem in windows 7 - all my problems seem to be related to network adapters.  If it's a hardware problem - does anyone know if it could be another loose connection?  HAAC Ltd. only give a 3 month warranty on parts that seems just a little.  But if this anomaly is due to the production of poor quality - that is not properly connect the laptop then I'll go back their again if they are responsible.

  By the way – there's a switch wifi on the front of the laptop - but is not currently be recognized.

  If anyone has settings that I could check that can help - especially if some inhibit the use of wifi.

  Thank you very much

  Hello

  Your wifi switch not recognized is probably a hardware problem. The rest could be a hardware or software problem.

  Method 1:

  Lets start by doing a reset to coercive. Follow these steps:

  1. Unplug the notebook (remove power cord), then remove the battery.
  2. Disconnect all USB devices and the connections between the USB ports.
  3. Let the laptop only for several minutes.
  4. Then plug the power cord without connecting the USB devices. Then replace the battery.
  5. Plug each device in turn, allowing them to load the drivers of devices one at a time (plug in the appliance and wait its loading all its drivers before installing the next USB).

  The computer recognizes the USB ports? All of them or none of them?

  Method 2:

  Open Control Panel, Manager of design. Click the view tab, and then click Show all devices. From there, you can remove all instances of USB devices and restart the computer to see if the problem resolves. Repeat this procedure with the wireless adapter (uninstall and reinstall, ensuring that there is only one instance of the wireless adapter).

  Method 3:

  Create a new user account by following the instructions in this article:   http://windows.microsoft.com/en-US/Windows7/Create-a-user-account . Does this solve the problem?  If the problem is resolved in a new user account, this means that the old user profile is damaged. Here is the link to repair a damaged user account: http://windows.microsoft.com/en-us/windows7/Fix-a-corrupted-user-profile.

  Try these methods and post your results here. I'll be here waiting for the results!

  Kind regards

• HP Officejet 8500 A909g is not recognized by my computer when plugged into the usb port

  I received an email from HP recommend I install new software for my Officejet Pro 8500.  I downloaded the software and installed.  The printer was working, but it would not scan. I got an error message telling me to re install the software because the analysis part has not been installed. I have downlaoded software again and installed it. During installation, the mode had to unplug the printer, so I did. (It is connected using the usb cable directly to the back of the computer).  When installation instructions came at a certain time, it told me to plug the printer. I did, but it was not recognized.  I checked the box to install all the software and install the printer later.  Now is back, and the printer is still not recognized by the computer.  Help, please.

• Can not use the USB ports on my Satellite P10

  I have a laptop Toshiba Satellite P10 3 years computer that has 3 USB ports. None of them works although the power is coming from them than my external mouse upwards but lights does not work. In Device Manager it says that everything is working ok IE all the drivers, etc. I was told that it's probably the motherboard?

  Maplins it's a software problem. I tried a PCI card with USB port but they no longer work. The PCI location is fine but as my wireless adapter card works from there ok. I restored the computer 3 times and each time the USB ports do not work.
  Any suggestions? I want to add an external mouse drive DVD etc...

  Any help appreciated... Mark

  Hello

  Did you use the clean Toshiba Recovery CD to restore the operating system on your laptop or have you installed the operating system from the original Windows CD.
  I advise to use the Toshiba Recovery CD because all the driver and patches installed on this CD.

  The USB ports provide a current of 500 ma, and it is a standard. If several external devices connected to ports needs more power as 500mA, then it of possible that the laptop does not detect USB devices several.

  In Device Manager, you may turn off the power save the unique option to the USB ports.
  You can do this in the properties of the USB port

  Additional I advise to use a USB hub with external power clean.
  These devices are not very expensive and will allow you to connect and use several devices together.

• iPhone 7 will not play audio via the USB port on the car.

  When I plug my iPhone USB port 7 more in my car (15 Jeep Grand Cherokee), the artist/song/podcast information appears on the screen, but the sound plays through the speakers of the phone.  I have confirmed that my settings are all the same as they were on my 6s, who played without any problems via the USB connection.  Bluetooth streaming works fine - no problems at all.  Any ideas, or is this a problem similar to that people have with CarPlay?

  Welcome to Apple Support communities, kevo.mac!

  Congratulations on your new iPhone 7 more! I see that you connect with your Jeep Grand Cherokee using the USB port. Everything seems to work fine, except that the music plays through the phone instead. I'll be happy to help you to get this working.

• USB stick not recognized by the computer. Have tried all the options I can think about.

  Very well.  I have a S-Mini Patriot 32 GB flash drive that does not recognize my HP Slimline 400-434 Windows 8.1. In my view, he acknowledged once and has refused to do since. My laptop (Windows 7 Toshiba) recognizes very well.

  All other devices USB function perfectly on this computer. USB hub mouse, keyboard, USB, cable Apple iPhone.

  1. I tried to unplug all other USB devices before trying this one. IN CASE OF FAILURE

  2. I went to device management and the USB does not appear in the list. IN CASE OF FAILURE

  3. I uninstalled the USB root hubs and restarted the computer. IN CASE OF FAILURE

  4. I tried to plug in the USB ports on the back that plug directly into the motherboard. IN CASE OF FAILURE

  5. I have updated the drivers, and have been unable to find a update of the BIOS as the link on the HP download site and told that it is incompatible to my computer. IN CASE OF FAILURE

  .. then what the hell gorram bloody I do now?

  Good and the most ridiculous way, I never solved a technical problem...

  Failed to insert the USB flash in the port. She has to insert slowly, so that the contacts are aligned.

  I found it trying to connect to it in my USB hub and noting that the witness red light was going on and outside that I inserted the USB key, flicker on as I inserted it there and then off once it is all the way in.

  Weird. But good. It works now.
