• Satellite P - 20 MB/s only through USB ports

  Hello!

  I have a problem with all 4 USB ports. When I plug a memory stick or does not recognize my external hard drive, Vista said it. But properties all my ports are 2.0. With my external hard drive I have tranfer only at 20 mb/s, is this normal? And yes my BIOS is up to date!

  Thank you

  20 MB/sec seems normal. USB2 is only capable of 480 Mbps. divide by 8 and you get 60MBytes/sec. But there are charges of USB protocol, so in reality the transfer rate is only about 20 MB - 40 MB / s

  If it was running in mode 1 USB, it would transfer only to about 1.5 MB/s (12Mbit/s)

• A2109A: Strange battery charging through USB

  My 1st try with stock ROM ICS has been, an A2109A stop never laoded 80% at night from a shutdown of PC with a standard cable to PC. Then I upgraded to JB and the same pc with the same cable it loaded to 100% within hours. I loaded several times this way.  And then it does not load more than 40% for 2 days. With the original charger I could charge to 100%.

  Someone at - it similar experiences?

  USB ports are only spec'd to support 1/2 amp devices which need power.  Some may deliver more, but the specification is 500 my (1/2 Ampere).  Your charger tablets delivers full 2 amps or 4 times the power that a USB port is supposed to provide.  USB 3.0 ports can offer 950 my or almost double the power, but still only half of what it takes, most of the tablets what whether the brand will be will not charge out of a USB port.  It is not a problem with the Tablet, but a limit of the USB specification.

• I made the mistake of disabling all my USB ports in Device Manager! Keyboard & mouse do not work. I need to restore the Sys - HELP!

  I made the mistake to disable all my USB ports in the device (Windows XP Home Edition) my mouse Manager and the keyboard works not because they are connected through USB ports. I need to find a way to get to the system restore through the Mode without failure or normal startup. Can someone please help!

  Hi PaulCanik,

  • Do you use your laptop or desktop computer?

  Check if keyboard works in basic input/output system (BIOS), if it works, then you will need to enable USB port from there.

  You will need to contact the manufacturer of the computer to aid in the basic input/output system (BIOS).

  If this does not help then you need to connect PS\2 mouse and activate later all USB ports on the computer.

  Important: Change (CMOS) BIOS/complementary metal oxide semiconductor settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.

• CarPlay audio quality of the voice when it is connected through the USB port is poor vs Bluetooth on Pioneer AVH-4200NEX

  Hello!

  I recently installed a Pioneer AVH-4200NEX unit, I was super excited to improve my car with the support of CarPlay, and everything works great except for one thing.  When I connect my iPhone (6s +) to the unit via a USB cable and a standard phone call, the audio quality is very bad - hail, very downsampled, and metallic sounding compared to the use of Bluetooth via the unit to pioneer for the same phone call (I'm on LTE, using HD voice, although the quality difference is quite noticeable on the calls not HD and on the 4 G calls).  I looked for an answer to this question, but the best that I can find mention of limited USB bandwidth and try to juggle than the bandwidth for the rest of the CarPlay experience, although I don't buy not because audio via the iPhone connected with USB playback is just as clear that it is through Bluetooth.  So my question is: How can I submit a bug report Apple about this behavior and (b) do you have other CarPlay users also be known this recent problem on a unit of Pioneer NEX (AppRadio included)?  It would be great if this is a bug of Pioneer for which they can release a firmware update, I'm just worried that it is a codec problem specified by the CarPlay, so non repairable.

  Thank you!

  Hello served,

  Thank you for using communities of Apple Support.

  I understand that when you use the USB cable for your iPhone in your car with the audio CarPlay is mediocre. I know how it is important for you to hear your calls clearly. In a situation like this, I recommend the steps described in the following article to help solve the problem.

  Configure CarPlay to use with your iPhone

  Specifically the section to get help:

  Get help

  If CarPlay does not work as you expect, here's what you can check. After each step, try to use CarPlay again.

  1. Make sure that Siri is turned on.
  2. Restart your iPhone and your car. Depending on your car, you can see the CarPlay home screen when you turn it on. If you do not, look for the CarPlay logo on the screen of your car.
  3. If possible, connect your iPhone to a different USB port in your car.
  4. Try a different lightning to a USB cable. Make sure that the cable is certified.
  5. Update to the latest version of iOS.
  6. Check the manual using your car. You may need to install updates of firmware for your stereo.

  See you soon

• Question of Toshiba AT10-r: charging: mini-usb connector port is broken

  My tablet to-10A is plu 1 year bit (expired warranty then). It will no longer charge. I have already answered a few messages in the forum that indicated similar problems. Let me continue on another where I can give you a few other updates.

  There is no need to do the "factory reset" procedure because it is a hardware issue. (I have done, but as no change provided).

  I opened my Tablet and tested with a multimeter. It seems that the mini-usb port is broken (see the attachment, the 5v PIN is not in good shape), basically I don't have 5 volts there. Precisely the mini-usb port is part of a small circuit hannstar e89382 arc10L_usb_sub. That's what it should be changed. I tried to get him, but I can't find one.

  Toshiba allow this component?

  Any other idea of the people in the forum? I saw a new mini-usb port of welding, but it won't be easy, at least not for me.

  Best regards
  Luca

  Luca,

  The EU standard warranty is 2 years, but in your case I don't know how the USB port is broken. Toshiba will have to fix if it proves to be a part of the defective material. Give it a try.

• When I plug my Galaxy s captivate phone into the usb port on my computer, it will charge the phone but will not allow sharing of information from computer phone.

  Original title: usb with smart phone problem

  When I plug my galaxy s captivate phone into the usb port on my computer, it will charge the phone but I cannot share the news from computer to phone. In fact when I click on the computer icon, it shows the dvd, floppy disks and hard disk but not the phone. I use a mouse usb and headphones and they work fine. I tried to search for devices and it does not work. I run Defender pro anti-virus software and have checked the firewall, but I don't see that his block the phone. I don't know what else to do. Help, please. Thank you

  Hi Mike,.

  Just to follow up with you on that, that very well may be the cause. Especially when it comes to mobile phones, the real cable you use is very important to have all the features when it is plugged into a computer. Where you can try a new USB cable yet, I hope that whoever is completely compatible with this phone.

• Sansa Fuze: Play through the car stereo with USB port

  I bought a fuse to play through my new car stereo using the USB port in the car.  It works fine if the the "rocket" plays internal memory, but does not work when I insert the micro-SD card [even tho SD card works fine in rocket not connected to the USB auto]. Any ideas? Sansa says lack of his car, but car people say no, and highlight car cannot distinguish which comes through the USB. On the same topic, someone tried to use a "USB" port USB auto?

  I can't speak for the part of SD card of your question, because I have not yet tried my rocket in my car.

  When you connect a rocket to a computer, however, the SD card appears as a separate drive. Maybe the radio cannot deal with the way in which the "rocket" offers access to the SD card. There is (cheap) USB key in the form of micro-SD card readers. Maybe that would fit your purpose here. Simply put the micro SD card in the drive of the USB and put the USB in your car stereo.

  USB USB keys should work properly in car radio with a USB port. I tried several disks to different USB memory and they are all worked well.

  I have a Thinkpad Edge E520 1143 AK7, working on windows 8, 32 Bit Pro.

  From somewhere in the settings I had turned off load option on ' always - on ' USB port since I did not have a smart phone.

  Please note that I have activated all 3 BIOS options and 'refreshed' the machine to the default state.

  Please note that charges USB port when the system is started and stopped when I stopped the load PC.

  But no luck. Ask for your help on the same.

• 3/4 USB ports cannot connect/charge iPhone/iPad

  I have an iMac 27 '' new. When I try to connect my iPhone or iPad, I have this problem on 3 of my 4 usb ports. The devices are sounding as if they connect, but continue to do so and therefore don't actually connect, load or let iTunes sync. "ding, ding, ding, ding, etc...". "I normally use Apple cables that work on my other computers or when it is plugged into the wall outlet, it is not the cables. My iPhone has the new cable and my iPad is older with cable connection/old - they both have the same problem. The first port seems to operate normally.
