Satellite P850 - right USB ports stopped working
I have a new P850 Satellite, after a short period, that the two right usb ports stopped working, I had only a wireless mouse connected to them at the time. Is there a reset for these ports, I tried to uninstall and reinstall, no change.
Anyone has any ideas.

What have you tried to uninstall or reinstall?
Hi, I am currently on "Toshiba Satellite C655"run"Windows 7 Home Premium". It's a laptop of 2009 model (2 GB). Last night (24/02/14) my USB Ports stopped working, they have been and continue to read anything every time I have to plug my devices. I usually only connect a cooling block and a USB mouse to the computer. They worked perfectly until I disconnected the. When I reconnect them, they work momentarily, and then I hear the beep sounds when you eject a device. I tried to connect several flashdrives, a printer, and one I tried the following hotfixes:
Note: The order of numbering has nothing to do with the order, I tried to apply each patch unless specified elsewhere. This computer had Windows 7 Home Premium REINSTALLED at some point. Just for your information. This message was made when there are others with the same problem is due to the fact that no solution not specified by Microsoft Technical Support or the Microsoft community were effective.
1) System Restore to the last known point, where they worked (and still). (Point restoration @ 15/02/24)
2) Windows Update
3) turn off the computer, disconnect the battery and the power supply and holding 'On' button for 10seconds.
(Note: whenever I turn on the computer now they work only for a moment, usually from 60 to 180 seconds.)
(4) Start > research ' Device Manager '> "De Bus USB controllers" Expand and turn off and restart the computer. They are re - activate automatically but my problem persists.
(5) download and run "Microsoft FixIt.WinUSB... ", on the 1st, I had a problem with devices not updated. But I actually watch updates by using Windows Update and ""searching for hardware changes "" on USB Bus controllers "." I then did a 'System Restore' and now Microsoft FixIt found no problem but the USB Ports don't always work.
(6) will ' services.msc"and change the Startup Type of Manual to Automatic for Windows install and restart Windows."
I am really lost with this problem now. My laptop works and worked perfectly fine until this problem occurred. I have fixed minor problems with computers before, but this is a bad joke for me now. If someone could please help me with this problem I would appreciate it a lot. Thank you very much.
Thank you for your help, but I discovered something funny on my computer. My cooling package (product name: Laptop Cooling Pad NSB;) HYCF-6181-2 model number) is to disable my USB ports when I plug. If I leave it unplugged and restart my computer, my USB mouse is still working on a port. Also tried using my USB and other devices. The problem is my block of cooling that strangely disables my USB ports, whenever I plug. Thank you very much for your quick response, fortunately the answer might help me in the future. For now, I have solved my problem.
After application of the 12 updates successfully (KB890830, KB2508272, KB2506223, KB250212, KB2508429, KB2507618, KB2509553, KB2503658, KB2506014, KB2491683, KB2511455 and KB2446710), my USB ports stopped working after restart. I get this description of Device Manager: Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might be installed a file that is signed incorrectly or damaged, or maybe it's a malicious software from an unknown source. (Code 52)
I restored the functionality of USB ports by doing a system restore before installing updates.
What should I do? Ignore ALL updates future windows 7, which leaves the system vulnerable? Help is appreciated thanks.
I solved this.Device-USB controllers-online standard uninstall online Manager pci improved to (do it twice) usb host controller, and then the scanner hardware change and let the win7 to reinstall the drivers.Updates were corrupted somehow the drivers, you need to fix manually.
Windows 7 Pro. All USB ports stopped working. When I plug a usb card, windows makes the sound as it connects and the card gets power (light). I see the map appear in disk drives in Device Manager. The player does not display in windows Explorer or disk management. In Device Manager, it has an exclamation point and says that the device cannot start.
Strangely, I have a USB keyboard and mouse and they work very well.
It's just the USB drives and chips and SD cards that are not displayed.
Reinstalled the drivers USB MB
Flashed the BIOS with the latest version
Tried to install the older USB drivers
Tried to let windows find the driver.
Still does not
None of this has helped. I ended up formatting the HD and reinstall windows from dvd.
This revealed that my USB multicard reader was bad. When I unplugged the problem disappeared.
I have a BOUNCING problem with usb ports on my qosmio g50-10 h.
There are two ports on the right side of the machine and I have 2 self-powered 7 centers of port (usb 2) attached to these.
Every now and then to stop it from ports and of course all the parts a unregcognised, not found.
I get error messages saying unregognised device or usb device stopped working or windows stopped device etc.
Unplug the hub and repluging it ususally actually come back to life.
Have you tried to connect devices directly to the USB port?
Try this and see if the USB device is disconnected, as you mentioned that using the external USB hub.
Generally speaking, it is difficult to say what might cause this
You could try updating the chipset driver.
Of course, you should also check the USB port settings, and power management options for economy.
In device manager-> USB root & hub-> properties you could disable for unique energy saving USB ports.
This also on Win 7 power management.
Hello. Deploy a Satellite 1900-303 with two USB ports. One of the ports stopped working. I guess it's permanently broken. Just browse the site, it seems that the easient of thing to do would be to get a Port Replicator - one of them:
http://UK.computers.Toshiba-Europe.com/cgi-bin/ToshibaCSG/JSP/individualOptions.do?service=UK&selCategory=4697&o ldCategory = 4697 & OPTION_ID = 95631 & toshibaShop = true & t ab = 1 #1
I wanted to know is it just to sink my remaining a USB port, so that I get 4 USB ports (and all others)? What USB speed I would get?
As far as I know the unit supports USB 1.1
So I guess if you are using a USB hub external, USB ports work with USB 1.1 properties.
Maximum data transfer should be 12 Mbps
first sorry for my bad English, im from Germany.
My new clearly L850 satellite has had some problems with sound-Port USB.
I think it's the Usb3.0 Port on the left.
While I'm workin with an external keyboard, the USB Port has stopped working and cannot identify the keyboard.
All other devices that I put there, are out of order, but when I put an external hard Powerdevice with separate data for laptop, that he is there something ist connectet, but can't identify it.
I have try all troubleshooting close it, like install new drivers, disable ports and restart and any kind of it.
So maybe you have another tip for me?
Or do I have to bring my laptop to the store for warranty?
A Windows 8 64 bit on it, maybe it will help.
Best regards, neothic
Have you tried reinstalling the driver USB 3.0? Please try and check the functionality. If this will not help I recommend you do the ultimate test: back up all your data and reinstall Win8 using recovery media. Test it with clean OS preinstalled and factory settings.
In the worst cases, you should contact the nearest Toshiba service provider and ask for help.
Hallo, I am DESPERATE for help, please.
I have a Toshiba laptop Satellite A200 series with 32-bit Windows.
My USB ports give me major problems.
I use a USB Internet Modem on multiple computers and it works fine on all computers, including Toshiba.
A month earlier, Internet USB would suddenly and constantly disconnect itself from the Internet, when I use it in the USB one. When I use USB port two, he recorded no more. The port does not have the device.
Two USB ports work well when used by other USB products.
I had always used Internet USB into the USB port, with a cooling for my laptop fan, USB 2 port. Now, when I insert the cooling fan, USB Internet disconnects and will not register, at least I have remove fan, remove and reinsert the USB Internet.
I did the following:
1. start an anti-virus
2 uninstall, re-install and update all the drivers for the USB, chipset famlies, Internet Modem ports, EVERYTHING.
3. I checked with my Internet provider, the problem lies in my PC, not them.
I don't know what to do, I'm tired.
Now, when I insert the cooling fan, USB Internet disconnects and will not register, at least I have remove fan, remove and reinsert the USB Internet.
I think that it is a problem of USB power.
The USB 2.0 port provides 500mA, and in some cases more than USB ports can be connected to the same power supply to the motherboard.
In case the USB device connected (in your case fan) would need more than 500 ma, it could be that other USB devices do not work correctly.
I recommend you go to Device Manager and select the properties of USB controller.
The last "Power Management" tab contains the option to turn off the device to save power.
This option should NOT be checked. It should be disabled.
Check it out.
My USB ports for Entertainment of HP Pavilion laptop dv7-2277 cl stopped working.

I have a problem with my Satellite M30-106. One day, the system froze (Windows XP with SP2) during the passage of the machine off. I was forced to keep the button "power" for a while in order to close the system. However, since all 3 USB ports do not work.
The system does not recognize the "" them. I can't see in Device Manager. I tried to reinstall the system, but it did not help.
Can someone help me, pelase =)
It looks like a hardware problem. At whatever it is connected to the USB ports at the time? Could you check the USB ports visually and see if they are damaged or wobbly. It is a bit of a long shot, but you may have a short circuit decision and which could disable the USB.
If the motherboard is damaged then outside fixing/replace your only option would be a PCMCIA USB card, they are not expensive.
As a result, none of the 3 USB ports on my old MX30 work of 2 months. I unchecked the option in the hardware Manager of devices for energy saving, nothing helps. First of all, only the mouse stopped and I thought the mouse was to blame, but all of a sudden the machine does not recognize the USB memory key more.
Any advice would be very welcome, because I can't work!
Respond to my ad. I've updated the drivers for the USB host controller and BIOS and USB ports running again.
I can't give info much more than that, but my computer has just stopped working.
I had owned the PC for less 2 hours, but while I was installing some programs the computer will just empty. It seems to be quite dead.
It fails to turn on, the light indicating it is connected is not yet lit.
I have no idea what could be wrong or what caused it to stop just but it is rather relative. The only thing I can say is he was running rather hot, I never expected to get so hot, but I assumed it was normal given the processor, it is running.
An hour after initially breaks I tried to turn it on again, but nothing helped. Does anyone have and suggestions/recommendations for my next course of action?
