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)

  • Satellite M300 - works only one USB port on the right side

    Hello

    in the series of M, Toshiba M300 satellite (red), there is a port USB combo and something else, and also another USB port ordinary on the * left * side of the laptop. There is also a USB port on the * right * side.
    Currently, for some reason, on my right, the USB port works (in other words, the laptop detects) and my left side, where there are 2 USB ports, it does not work (in other words, it does not detect it) I have no idea how solve this problem.

    And what happens if you connect the external USB mouse?
    It work?

    > I have the toshiba recovery of the burned disc, should I use it?
    Why not, you can test it with the new operating system preinstalled too.

  • Satellite Pro M70 freezes everytime when the USB port is used

    Satellite Pro M70 (SPM76) crashes every time when the USB port is used.
    The mouse works, but external HD/Extarnal card sound/Memory stick causing the laptop to freeze. All the drivers are installed right, they are the most recent and have no trouble with other users.

    The devices are all compatible. Service pack 2 is installed, and all the hardware drivers on the toshiba have been updated... again, same problem.
    The toshiba is about 2 months old and have had this problem since I got it. First I thought it was the drvers, but I cleared of all (?) other options but the USB ports.

    Hello

    Believe me, that's not easy to say what the problem may be. It is important to see if the problem occurs because of hardware or software may be. I recommend you to backup all your data and reinstall the unit using rescue media. On this way the unit will be factory settings and will be clean preinstalled. Test your USB devices and see what happens.

    Try to use some standard like USB stick or external HARD disk parts, because in this case, you must not install any drivers please. If you use other devices like USB webcam with own software and drivers, it is possible that something goes wrong, but what. On this path, it is not possible to say.

  • Satellite L500 - high-pitched noise when the USB port is in use

    I have a Satellite L500-1ZP, aged from 1 month. When I connect a usb key or other device in my usb port, the laptop generates a high-pitched noise.
    The sound is not strong, strong but enough to irritate me.
    When I disconnect a device, the sound disappears.
    The sound is also there when I disconnect my laptop to the grid form.

    This is a common problem and can it be resolved?

    To be honest I don't think that this is a common problem. Is that what you found more threads with the same description of problem?
    The same happens when you use the available USB ports?
    You can locate where this noise is coming from? Maybe the speakers?

  • System only through headphones - no music sounds. BUT... the music only through USB speakers. No system sounds. What is happening with this?

    I listened to the music on my computer through headphones regular plugged into the audio jack of 3.5 mm.  I could hear the computer through headphones - music, movies, YouTube, system sounds - everything.

    Then, I plugged my Microsoft Digital Sound System 80 speakers via the USB interface.  Windows XP found the speakers, loaded the right driver, gave me the message "your device is ready to use" and things started to play music that was running on the computer.  Sounds incredible.

    But now, I have a weird problem.  I can hear only the sounds system through headphones (beeps and dings that play during system events), but I can't hear the sound system on the USB speakers. AND... I can't hear the music/videos/YouTube, etc. on the speakers USB-interface, but I can't hear the sound system through the USB speakers.

    When I go to the audio tab of the sounds applet in the control panel and change the device for audio playback by default "SoundMAX HD Audio" to "Microsoft Digital Sound System", then I hear everything - system and all - sounds on USB speakers.  But then I hear anything through the headphones.

    I want to be able to Exchange music back to making the USB speakers.  How this is done?

    Yes, they are older speakers.  But they work a lot.  And the digital sound via the USB interface is excellent.

    Hi BitSpanker,

    The only option is to change the audio device by default for the device that you want to hear the audio.

    (a) click Start, click Control Panel, and then click sounds, speech, and Audio devices.

    (b) click on sounds and Audio devices, and then click the Audio tab.

    (c) in the sound playback section, under default device, make sure the audio device is the correct default audio device.

    (d) If this isn't the correct default audio device, click the drop-down list next to the device name, click the audio device you want, and then click OK.

    Change the audio device may require that restart you your computer.

  • Satellite Pro C650 - USB ports now DEAD

    Over the past 48 hours have really struggled to get my USB ports work,
    Toshiba SATELLITE PRO C650 lappy running W7... At only 2 usb ports.

    A couple of days, I bought a new stick of memory... 16 GB SanDisk Cruzer Blade... He stuck in lappy and anything that happened outside my mouse attached wireless stopped working.
    Since then, the ports were completely dead. (stick now appears on anotherPC)
    That's what I did so far, after a search web solutions thro...

    Device Manager display ports everything is OK with no exclamations...
    When I insert any USB device... no sound confirmation of PC and Dev Mgr flinch...
    Tried to uninstall port/hubs and leaving W7 re-install them using... Still dead...
    Trying to remove battery and power sector during the centuries, then re start off the power... Still dead...

    I think that my last resort looking for a factory system by default re install... but one have a mountain of things astro which must be saved and cannot be done through many many discs.
    I really want to be sure ive tried everything before you do this.

    Could I have really damaged the MB. ??
    I now nowhere so fast if theres anyone out there has any suggestions please shout...

    > I think that my last resort looking for a factory system by default re install... but one have a mountain of things astro which must be saved and cannot be done through many many discs

    Even if it s really painful to get everything installed it again, I would recommend to recover the laptop using the Toshiba recovery disc or HARD drive recovery.

    > Could I have really damaged the MB. ??
    Well, it's hard to say before trying the recovery procedure.
    If the USB ports are not working after using the recovery disk (or HDD recovery), then of course: the mobo may be affected, therefore, in my view, the laptop must be set to the factory settings.

    Hello

    The problem is that the dysfunction is definitely related material and cannot be resolved by setting options in the BIOS...
    So. NO, West, nothing you can do. Just send the machine to an ASP and let them repair your beautiful Satellite. ;)

  • USB ports not working not not on Satellite Pro C650 - 18 d

    Hello
    I have a Satellite Pro C650 - 18 d on which USB ports are dead.
    So far, I've updated the chipset and BIOS - but they stay dead. It doesn't seem to be a power either. I have a USB key with LED and it does not light.

    Any ideas? It's under warranty and so unable to try something wild!

    Thanks for any help
    Jim

    Hi Jim

    I recommend you to reinstall the OS and test the feature with the factory settings. Please, test it with several different USB devices. If none of them works, you must contact the Toshiba service provider in your country and leave check s portable.

    Do you know how to find the addresses and phone numbers?

  • Satellite A200-1tw psae6e - USB ports not working not

    I use windows 7 ultimate on Satellite A200-1tw (psae6e-06u030du) and my usb ports no longer works correctly.
    In fact they recognize certain usb devices, but not all (for mouse and printer example work, but my USB does not work)

    Looking at the Device Manager, everything seems OK... No problem!

    Does anyone have a solution for my problem.

    Thanks :)

    Hello

    Try resetting the USB ports. This means that you need to remove the USB ports/hubs/controllers in Device Manager.
    Then, you have to restart the laptop to get new USB ports.
    In my case it has worked.

    By the way; I recommend upgrading the chipset driver and disable the feature for each energy-saving usb port.
    This can be done in the Device Manager-> port USB-> properties-> tab to save energy

    Hello paula407, the 6 in 1 card reader shows there: cards 6-in-1 Reader + 2 USB + 1 taken line-in

    This suggests that the card reader has only two USB ports on the front of the system and the other USB ports would be on the back or side of the system.
