  I can plug my external hard drive directly into my laptop and it is detected instantly.  If I use the external hub, the drive is not detected.  all the drivers are updated, no conflict of resources in "not advanced" deactivation of controller caused improved host machine to freeze and had to do a restore.  There are many applications of this kind.  Please note that the procedures on Hub controllers to uninstall gave results little according to the correspondence of blog.  No matter what other tactics very appreciated.  will try to uninstall, but skeptical.  Intelligence is in the hub of USB 2.0 on the laptop, as evidenced by its ability to detect.  He can not just extend to the external usb hub.  Please advise, it defies logic.

  Hello

  The player and the hub are not compatible I've seen. Maybe try a different HUB.
  (Is the HUB you use powered, otherwise this could also be a possible cause of wiring).

  I hope this helps.

• The heat of my computer a lot and it suddenly stops when Im playing certain games.

  My computer get too hot and it suddenly stops when Im playing certain games. Can you give me any advice to solve this problem. (I would like to format the pc and put it as the 1st time using, but I accept more tips) I have a cooler, but I think I'll buy a new one.

  With the computer turned off and not plugged in you should carefully blow out the fan and radiator.  Laptops are not suitable for playing games in the first place.  If the cooling block does not help and the computer is more than a year, you may need to reapply the thermal CPU paste or frankly just not playing games with her.

• External USB hub limit for Satellite Pro C650

  Is there a limit to how much you can connect via the Satellite Pro C650 of external usb ports?

  Provides four ports hub I, ports seem to work individually and all devices operate normally when plugged directly into the top of the Tower, but when all devices are plugged into the hub and combined high tower, there are future errors.

  Thank you
  Karyn

  Well, I think that this should not be a problem if the unique USB hubs provide clean power.
  The fact is that the only USB port provides common 500mA and if several devices would share the power of a USB port then it might be possible that the 500mA available would not be sufficient for all USB devices.

• Satellite M30X-129 loses connectivity with the external USB device

  I have a problem with my laptop that has regularly been do worse and I can handle is no longer!

  Whenever I work with external devices via USB ports (all kinds of devices but my external hard drive Smartdisk CrossFire and my iPod in particular), after a certain period of time (sometimes minutes, sometimes hours) the laptop loses connectivity with the device.

  If happens to be listening to the music, download photos from a camera or laptop computer for the ' net or sync of the iPod, the connection is cut off, turning off the device and I have to start all over again!

  I'm almost at the point of launch of the laptop by the window, so any help is most welcome.
  Thank you

  Hello

  This happens also with the external USB mouse?
  This occurs if the power adapter is plugged or only if the laptop running on battery?

  In-hubs properties > Device Manager USB root-> power management
  You will find the option called allow the computer to turn off this device to save power.

  I would recommend the brand and disable this option.

  Maybe it helps.

  By the way; When do you update the operating system? I think that it s there long time, perhaps some system files or registry entries are corrupted or a 3rd party application affect the USB functionality?

• Portege Z930-118 does not recognize the external USB CD/DVD drive

  My new Z930-118, with windows 7 64 bit home, does not recognize the external CD/DVD drive when I plug it into the USB port.

  The CD/DVD device does not even appear at all in Device Manager.

  The reader is a SE-S084 Samsun and works well on another laptop.

  I already checked for the "upper_filter", "lower_filter" with the regedit, but entries are not there, so no help.

  Hello
  I m not very well how to help you.

  I found some information about this WEIRD disc and it seems that he didn't need an external power supply. Its USB bus powered so I guess around 500mA power since it is the default value provided by a USB 2.0 port.

  I don t think that there is a problem of missing software. It is a plug n play device so you need to connect it to the USB port and the system should automatically recognise.

  From my point of view of the few you try to connect the external USB ODD two ports to aid a * Y * Cableusb.
  I think the reader needs more power provided by a single USB port.

• Problems using external USB hub with A30

  I have a Toshiba Satellite A30-514 with a USB powered 2.0 hub attached. In it's plugged a powered satellite Receiver/USB modem (for connection broadband), a USB bluetooth adapter and a HP PSC 1350 printer. The first two devices work fine, but the printer is not recognized correctly.

  The powered USB hub is plugged into the first USB port on the laptop. The second USB port on the laptop is used by the receiver for a wireless optical mouse. It must be here otherwise, it does not work.
  If I plug the printer directly into the second USB port on the laptop, it works fine.

  In Device Manager, instead of show all HP devices it comes to peripheral USB Composite in the USB controllers section. It is an orange exclamation next to him.

  If I boot the laptop with all 3 devices plugged into the hub and turned on, the printer is detected fine but the Bluetooth Radio devices have an orange instead exclamation point. I need the bluetooth device to attach a cell phone to the laptop. If I unplug the printer and restart the bluetooth is detected OK. Plug the printer in causes the Composite device to reappear with the exclamation point!

  From left to right, looking at the front of the hub, devices are 1) satellite receiver/modem, 2) Bluetooth printer) 3.

  I hope it's clear. Any help / advice would be received with gratitude.

  Hello

  I think the problem is that one of the devices does not have enough power to operate. This is because a single USB port must provide 3 devices with power. If you have an external power supply to one of the features of this you should use.

  Good bye

• Satellite M300: speech recognition only works with external usb hub

  Hi all

  I have the Satellite M300 I could run the speech recognition program before you have the motherboard replaced due to failure of the usb.

  I found using the headset, I can not reach high enough quality to operate it.
  The only way I can use the Word program, use an external usb hub with its own power supply.

  The problem concerns the audio card, or simply not enough voltage?
  And na fix?

  See you soon

  Hello

  The notebooks of USB ports provide a standard power of 500 my.
  As I said that it is a standard, but in USB devices different part 3 external cases need more power.

  For example, one of my external USB 2.5 HDD s must be connected with two USB ports at the same time to ensure that the HARD disk would get enough power to function properly.

  Your external card is unknown to me but maybe it needs more power as usual.

• Satellite Pro L500 - stops when the power cord removed

  Toshiba Satellite Pro L500 stops when the power cord is removed even with the battery to 100%. I removed the battery and all the indications associated with battery answer correctly. For example turns off, Toshiba Health Monitor also indicates when the battery is removed. If installed Health monitor indicates that the battery is at 100%.

  Someone please help. I have not installed anything new.

  Hey,.

  For me, the matter is clear: the battery can't hold a charge so the laptop will be shut down because it has no power.

  I think you need to replace the battery with a new one and you can get a provider of service authorized in your country. Simply contact the guy and ask that they can tell you how much it would cost.

  You can find a list of all FSA here:

• Satellite Pro L10: CMOS clock stops when the OS is not running

  Hello

  We know a reason why the cmos clock would stop when the operating system does not (phone off), the laptop is 18 months old, I've updated the bios tries to give him a good boost, but no effect, he was also in charge for 24 hours.
  Any advice would be great.

  See you soon
  Paul

  Hello

  Usually if the BIOS date/time is wrong and always changes, the RTC battery which is mounted on the motherboard fails.
  In this case the CMOS battery needs to be changed or maybe only removed for awhile

  If your laptop is 18 months, the guarantee must be valid.
  Generally if you have registered on the page of Toshiba notebook the warranty covers all repairs for about 2 years (24 months).

  In this case, I would recommend contacting ASP in your country, because the technician must be able to solve this problem very easily.

• MacBook Pro stops when the lid closes, loses the open tabs and background image...

  Hi all

  I recently had a new hard drive installed in my 2012 13-inch MacBook Pro. I am running El Capitan 10.11.2. Since then, my computer cuts automatically to the bottom when the lid is closed, losing all Web pages, and for some reason, some background, I've saved. (My browser is Mozilla Firefox and it prompts you to restore me the tabs lost, which he will).

  The led standby does not blink or light up when the computer is turned on, it will turn on only at startup. At startup, the login page is displayed, and after that I entered my password it takes about 15 to 25 seconds to load and open my account. What is going on?!

  Summary:

  Stop when the lid is closed,

  Loses the background image & open Web pages.

  Standby blinks only when starting,

  Time of loading extended after logging into my account.

  Any help would be greatly appreciated! Thanks a lot for reading.

  Take it back to the repair as well as your receipt of repair shop.  Apple has a 90 day warranty on all repairs.

  I just got a new series of Yoga 14. Sometimes, but not always, the laptop stops when I close the lid, even when it is plugged. I already looked at the option to 'choose what happens when the lid is closed' and it is set to sleep, no downtime.

  Any ideas on how to solve this problem.

• While the loop does not stop when the two values are equal using equal to comparitor

  Hello world

  I have a really, really strange bug. I have a LabVIEW VI that change a chain on a power supply. I have a start and a stop voltage and use a while loop to increment the device. For example if I want to scan from 1, 2V to 2.2 V in 0.2 V incremements, the program will end when "The current tension" = "stop the tension." And it works very well!

  However, when I start - 3 V and want to stop to say-0.8 (new in 0.2 V incremements) the program does not stop when "The current tension" = "stop the tension." I checked with the probe close to what should be the end of the race and - 0.8 V goes both of the entries ' equal to ' comaprison operator, but that his can't trigger a real result.

  It's very strange for me. Espeically as if I'm going - 0.8 V to-2 V but decrement of-0.2 V, the program stops correctly!

  I am very confused!

  See you soon!

  The second thread is particularly relevant. This discussion was 2009, but you can find that the same "bug" being reported to enter the end of the 1980s.
