USB ports does not work

Hi I have problems with not working USB ports. It used to work. I downloaded actual drivers at msi.com for my gaming notebook GX 60 Destroyer and now my USB ports does not work. What should I do?

What driver have you updated?
Try to do an EC firmware reset by removing the battery and the AC adapter then put the battery back with AC adapter attached.
Same questions like Pegasus asked, does all ports not working? which one exactly? What OS are you using?
Have you done any changes to the system? (for example: self-install OS or changing OS)

Back USB port does not work

I noticed that one USB port(All other ports appear to be working)in the back of my Mac Pro does not work.
Aside from taking my Mac Pro in for a repair, is there any other way to fix this problem?

You can always try resetting PRAM and NVRAM…

… and/or the System Management Controller…

… otherwise no. You will need to take it in for repair and most likely a logic board replacement.

USB Port does not work W510

Hello all,
I am writing to you hoping that one of you may have an idea what's wrong with my beloved w510.
A few hours ago the usb port (on the back on the right side) where I plugged in my external mouse stopped working.
In the Lenovo part list it is referred to as "usb Sub card yellow".
It just does not recognize a mouse nor any usb stick or external drive. I have already reinstalled the usb controller
but it didn't make any difference. (I think the driver is only for the usb 3 hub on the left side of the notebook)
when I plug in the external drive the lights of the drive start "flashing" same for the usb stick, but they are not recognized as drives..Same for the mouse. The lights go on, but nothing else works.
Probably its all my fault, but I don't know what else I can try! Please excuse my bad English...!
Hoping that somebody might be able to help me...
Paul

I have a reproducible test for this issue on my W510.
1) Plug in a usb mouse into the rear usb port and ensure the mouse is working.
2) Hybernate the system.
3) Resume the system.
4) Confirmed the mouse does not work.
5) Disconnect and attach the mouse to one of the left usb ports and confirm the mouse works.
6) Disconnect and attach to the rear usb port and confirm the mouse does NOT work.
7) Restart the system and confirm the mouse still does NOT work.
8) Shut down the computer (a full shutdown, not standby or hybernate).
9) Power the system back on.
10) Confirm the mouse is now working in the rear port.
I can do these steps over and over with the same results regardless of whether the AC adapter is plugged in or not. It appears that the data connection does not work after the system is resumed from a sleeping state. I have the latest UltraNav driver and utility and the latest power management updates.
Oh, and one more test. Hybernate the system with nothing plugged in, then plug in a mouse into the rear usb port when the system is presently hybernated and then power the system back on. The mouse will not work and rebooting doesn't correct it. Only a full shutdown fixes it.

USB port does not work with a screen

Dear All,
My manager has a MacNook Air 10.8 and he is using a large 27'' Apple screen.
He connects the screen to the MacBook Air with a cable which has 3 connections (USB, power, Tundetoh)
He reported to me, that some time, he connect a mouse or a keabord to the USB, at the back of the screen, the two devise does not work, while it works when the devise are connected to USB port of the MacBook Air.
His Macbook Air software are uptodate.
Does you know how to make working the USB devise connect to the screen?
And what does make those trouble?
Cheers
Pierre

One USB port does not work with external Disk or USB key

Hello,
Back to my iMAC there is 3 USB port. The second one - in the middle - does not work pluging an external Disk, an USB key or an iPOD nano. However it works well connecting a Wacom tablet.
Is there an explanation to this behaviour ?
More the keyboard is plugded on USB port 1 and the mouse on the keyboard. Time to time - especially at reboot - I have to unplugged the mouse and plugged again it in order it works.
In advance thank you for your answers
Regards

Since it does not work for three different devices, I will assume it is not something simple like a faulty USB cable. Since it does work for one device, I will also assume that the port is (at least partially) working.
As a test to narrow down the cause, I would try restarting from your Mac OS X installation disc (insert disc and restart with the C key held down).
At the first Installer screen (after language selection), go up the menu bar. Under Utilities, select to run Disk Utility. Now, connect the USB drive into that center port. Does it appear in the Disk Utility sidebar?
Please post back the result...

Flash player does not work under one user account.

Flash player does not work under one of my user accounts.
My system: I work with a mac mini with Mac OS X 10.6.8.
What I have done:
I installed the flash player maybe one year ago under my "first" user account. At that time this user account had had administrator authorization. In the meantime I had to change this "first" user account in an account without administrator authorization and created an administrator user with which I installed different programms. Lately, the message came up that it would be necessary to update the flash player. I did it; under the "first" user account, but of course with the administrator's password for installing. The installation had been "successful" - so I was told. But it did not run. I tried it again and again. Each time with "deinstallation" first. No way; it did not work.
After asking Adobe for the reason of the problem, they suggested to install the programm directly under the administrator user. I did that (of course after deinstalling under the "first" user account) with the result, that flash player runs under my administrator and my "second" user account, but not under the first user account. There I am always told to update my flash player.
With this result, I talked to Adobe. So they told me to contact the producer of the operating software, since this would be a mistake of the operating software.
And here I am - full of hope to get help from you.
Thanks for reading. And thanks in advance for helping me.

Any update to provide at all here guys? Again, in my situation, it's very much rights-related as a standard user doesn't even report that the flash player exists when testing it on the Adobe Flash Version Detection website (despite it showing up in Control Panel and under Add/Remove Programs). I've already tried giving the C:\Windows\System32\Macromed and files/subfolders appropriate permissions for the standard user and still nothing. If I either give the user in question full local admin rights or logon as the domain admin, then the Adobe Flash Version Detection website says Flash is installed and Flash works fine.
Thoughts???

E3200 - USB port does NOT work for more than one device

We needed a new router that had the dual band connectivity as our previous router stopped working properly when we started using a baby monitor operating on the same 2.4 GHz. The choice was between E3200 and E2500. We chose the E3200 mainly because it also offered a USB port. We were hoping to use that to connect our printer and two external drives (thus bypassing our old desktop that's been working as a server). However, it turns out that the USB port on E3200 does NOT support USB hubs! So, you can ONLY use ONE device - either a printer or one external storage drive. That wasn't really clear at all from the description. I feel like we wasted the extra $50 hoping to get functionality that just isn't there. Can't believe that in this day and age, Cisco thinks we all have only ONE USB device we might want to connect to the network! The router itself is fast enough, but the extra $50 for a USB port that doesn't do much and some speedboost phantom ability is just not worth it.

Just to save time to you all, after numerous attempts to install a USB hub to my E3200,
I wrote to Cisco Customer Service (live chat) and I specifically requested how to set up the usb hub or the virtual USB port and they said that they do not have a software to install a USB hub.
Hope this help

My usb port does not work

I keep getting a message that my usb ports are disabled because the device plugged in is taking too much power. I plugged in a passport 1 tetra hard drive.

What kind of computer are you using? Are you plugging in to an external keyboard or other device or directly into the computer? Does it work if you plug it into a different USB port, preferrably one on the computer?
Best of luck.

USB port does not work properly on Tecra M3

I need help with my Tecra M3 USB problems.
It has 2 USB ports. Awhile back the USB ports refused to recognise any non-driver USB memory sticks (I do not have any driver required sticks to try).
Recently I've had to re-install my Siemens ADSL modem, driver etc. which runs via USB cable - LAN connection 2 then WAN miniport. And this is now causing a problem.
1. the Modem LED tells me that it has power (it's a non-powered modem - Siemens C100-1)
2. the link LED holds for about 10 minutes (whilst I'm online) then turns-off (although the properties of the connections tell me that they are still connected)
3. other hardware - printer etc which is powered runs through the USBs OK.
4. the modem seems to be working ok because I can use it with an iBook without problems.
Could this be a USB driver problem? How do I find out? If so how can I fix it?
Thanks

Hi
Thanks for the notes - you're probably right with your suggestions, I've only just read your reply.
In the meantime I didn't have the patience so after much blood, sweat and tears - I re-installed XP.
The support team suggestion I updated my Wireless LAN driver, which seemed a little strange because I have never used any wireless device and didn't mention I ever had a problem with it in my initial problem!!
I'm going to back to a Mac when this Tecra is outdated :)

One usb port does not work

one of my usb ports is fine the other will charge but not transfer any data.

Thank you for your prompt reply. My Macbook is, unfortunately, older than one year and I have not AppleCare. I have been into the Apple store, they suggest me to buy an other laptop. Probably because the repair is more expensive than a new Macbook.
Anyway I have not intention to chane the computer because is less than 3 yrs old, and it wors very well except usb.
thank you again

Try a SMC reset. Google "SMC reset on Mac computer".

Exe created with Report Generation toolkit does not work for all users

I created a exicutable with the report generation toolkit and it only works with some of my users. I use microsoft 2007 and anyone that has microsoft 2007 my exe works well. Most of my users that have microsoft 2010 are able to use my program as well. However, there is one user with 2010 and Windows 2007 that cant get my program to work.
Any suggestions for troubleshooting this?
Thanks

The most likely issue is due to the fact that Microsoft changes the ActiveX object model of Office for each version of Office. The Report Generation Toolkit does a pretty good job of handling this, but it is not 100% effective. Search, for example on the "Set Cell Border" function and you will see what I mean. In these cases it's up to you to handle this issue. How you handle it really depends on your situation. For us to provide a more concrete answer you will need to provide further details, such as what toolkit function is "not working" (whatever that means), and who you "users" are. Is this an internal distribution? Are you selling this program? Is this code written for a project with a specific customer?

FF will not start up. FF does not work on other user accounts on this machine either, but works ok on another pc on our home network. Thanks for any help you can offer.

Computer is an HP Envy 17 laptop. Firefox does not appear on Task Manager list of processes or applications. System restore did not fix problem. Google Chrome works ok. Internet Explorer works ok until I try to download Firefox. Then it too crashes. This pc has been running Firefox fine since I purchased it 10 months ago. I upgraded FF3 to 4 then to 5 with no problems. Suddenly yesterday it stopped working. There is no error message and evidently FF does not launch because there is no listing of Firefox in Task Manager processes or applications. I tried uninstalling Firefox, then tried to download it usingInternet Explorer, but when I click on the download button at the Mozilla site, Internet Explorer crashes. I did a system restore to 8/16/11 when Firefox was still working. This restored the program but it still does not run. Google Chrome seems to run fine. My internet access is via wifi through an Actiontec router and Verizon Fios. I am running Symantec Endpoint virus protection and do not have any Norton or Skype programs listed in Control Panel. My pc is set for automatic updates from Microsoft and from HP. They both say my software is up to date. Is there a fix for this problem or is it a sinister plot by Microsoft to force us to use Internet Explorer?

Glad to hear it

Apple USB keyboard does not work with one internal usb port

Hi everyone,
hope someone can help me to solve my problem. I have a MPB13 retina late 2013 since something like 3 months. I have additional screen (dell), usb wired keyboard (apple) and BT magic mouse.
Since a few days, my usb keyboard does not work well. It only want to work properly when plugged to the rights side usb port internal port and not anymore on the left one. It also work on a usb external concentrator. Before, I had no problem, it worked perfectly. There was no problem such as cofee on it...
After searching the web on such problem, I tries a few things such as:
I tried the keyboard on another computer (windows): works fine
I tried usb stick and external DVD reading on the left internal usb ports: works fine
I switch the MPB off and turn it back on: the usb keyboard still does not work on the left usb port
I tried the SMC and PRAM reset : nothing
Any idea ??
Thanks
Guillaume
