Usb keyboard not recognized

Have a late 2012 macbook pro 13 inch running OSX 10.8.2. I want to use the apple usb keyboard and external display, but the keyboard will not work when I plug in the usb. I tried the software update and restarting. Any ideas?

I understand the Minimate is not just a USB hub, but it's USB expansion ports are still a hub from the mini's perspective. For this reason you should try plugging the keyboard directly into the mini, and I strongly suggest that as your best way to connect the keyboard.
If I understand your description correctly, when you have problems is when you turn off the display at the switch. This is probably the whole source of your problem, as the mini is then falling back to a 'headless' mode. I do not recommend this method. Adding the fact that your keyboard is not physically, directly connected to the mini I'm not surprised you are having such an issue. These types of circumstances basically make a Mac under OS X think it's being run as a system that's remotely operated.

Usb keyboard not recognized in mac - working in windows

Hello,
I am facing a strange issue with a usb numeric keyboard.
After some plug-ins/outs one night, it stopped being recognized in my iMac.
Actually, system profiler shows the following:
Vendor-Specific Device:
Product ID:          0x6560
Vendor ID:          0x04b4 (Cypress Semiconductor)
Version:          90.15
Speed:          Up to 480 Mb/sec
Location ID:          0x26200000 / 3
Current Available (mA):          500
Current Required (mA):          Unknown (Device has not been configured)
The keyboard, doesn't work either with my MacBook Pro. USB ports are working fine with any other devices.
I recently tried with a windows machine of a friend and the keyboard worked fine there.
Both my macs are running 10.6.8
Any ideas ?

I have the same problem. I found I can unplug the keyboard and when replugged, everything works OK.
I just upgraded to OS V10.6.4 and still must unplug and replug the keyboard in order to type.
WHY?

USB device not recognized in Windows 7?

I have the strangest problem I've yet to encounter with my computer.
As you may have guessed from the title, I am constantly getting the message displayed. Any fix that has been suggested has been unhelpful or worked for a bit until my computer restarted again (I'll get to that)
First off it started when I noticed my mouse pointer was acting very weird, it was just a vertical line of dots. A forum said an easy fix to the problem was to update my GPU drivers, which I needed to do anyway. So after an update to the GPU drivers
I log into my computer (which is password protected, this is slightly important to remember) and I try to go to youtube. I click down at the start menu to type in chrome and nothing appeared. I was able to move the mouse around and click on things
but I was unable to type anything.
Luckily for me I have a laptop as well so I checked for any solutions on my laptop and they said that it was a problem with the model of my keyboard specifically This was odd to me considering most of the problems happened OTB for the keyboard and not
a month after use, plus I was able to plug it into my laptop and it worked just fine. When I plugged it back into my desktop it gave me the same problem: I couldn't type anything, I also noticed the little pop-up informing me that the USB device was
not recognized. "Well, great, time to get my backup keyboard," I thought to myself. Except, that was not the case either. I plugged my backup keyboard into every single USB port on my Computer Tower, even going so far as to unplug
the mouse. Absolutely nothing was working. I constantly restarted my computer and each time got the same problem; I'm able to type in my password to log in and then a few minutes after that the USB device stops working. Sometimes after plugging
one of the keyboards back into a USB port I would get a message saying it was installing drivers; and then would fail in installing any.
After a bit I navigate through the menus with just my mouse and do a system restore to before the GPU drivers were installed. After that, I started windows in SafeMode and then turned my computer off. Finally, I unplugged my computer completely
of all plugs (including my power plug), waited a few minutes, then plugged everything back in again. Amazingly, this fixed the problem, but then it got worse.
After about an hour of gaming, my computer BSOD's, most likely because I decided to alt+tab out of Tomb Raider during a loading screen to stop a video I had on. I restart my computer again, and then the problem returns, only this time absolutely
no USB devices work except my one keyboard. The backup keyboard, and both my regular mouse and backup mouse stop working a few minutes after logging in. I try to fix the problem like before, but to no avail. Any USB device I plug in either
gives me the "USB device not recognized" or attempts to install the drivers and then fails.
If there is ANY way to fix this problem, it would be greatly appreciated.

Try cleaning the connector on the bottom of the phone. Use a magnifying glass to see what is stuck inside, a dry toothbrush and/or wood or plastic toothpicks (nothing metal). If that doesn't resolve the problem your phone is broken.

Help!! Ipod Video usb Port Not recognized !

Could anyone tell me what's going on with my ipod video 30g?
My friend borrowed my ipod for a file copy to his desktop, when I got it back and pluged it in the dock, the computer said: usb can't be recognized.
I am sure that the USB hub of my IBM is perfectly okay. And It is okay for the ipod to play music, photos and videos.
By the way, My friend's External Portable Hard drive also had the same problem after connecting to his desktop.
Have we got the Ipod usb port burned? Is there any way we can fix it?
Thank You!

It seems that many people are still getting the 'USB Device not Recognized' problem from time to time. Unfortunately there is no easy fix.
Firstly, it's recommended that you make sure every one of your motherboard drivers are completely up-to-date, but you probably already knew that.
In XP, after a USB port isn't used for a long while the USB driver built into the OS sets the OHCI controller to suspend. When you plug a device back in, it can sometimes fail to 'wake up' properly. This problem was supposedly fixed in SP1 but there is a related registry hack that may still be able to help.
Run regedt32.exe and navigate to;
HKEYLOCALMachine\SYSTEM\CurrentControlSet\Services\Usb
Create the Usb key if it doesn't already exist. Under this key, create a new DWORD value called DisableSelectiveSuspend and give it a value of 1. Then restart the PC.
A long shot perhaps, but I recall having similar problems with a USB hub built into my Microsoft keyboard and adding this key seemed to solve it. It wouldn't hurt in trying .
Alternatively, removing all entries relating to USB in Device Manager and all associated USB drivers will force XP into refreshing the USB driver stack.
Begin by unplugging all USB devices, then use Add/Remove Programs in Control Panel to uninstall any USB driver software. Next, boot up into safe mode and go to Device Manager. Once in device manager make sure 'Show hidden devices' is checked under the View menu. Uninstall all device entries in this order;
1. USB peripheral devices (printers etc.)
2. HID and/or Composite USB (Human Interface Devices) You're using PS/2 input devices so you may not have this entry.
3. USB Root Hub(s)
4. USB Host Controller(s) (Universal or Enhanced Host Controllers)
Then boot back into Windows (not safe mode) and it should populate the Root Hubs & Host controllers again. Proceed to plug your USB devices back in, starting with your powered hub. Be aware that most USB printers and scanners need to have their drivers installed first before you plug them in.
Hopefully some of this may be of help, let me know how you get on.

USB Device Not Recognized

Operating system: Windows Vista
Error: USB Device not recognized
While actively on the computer, we suddenly got a message stating that the USB Device was not recognized. The only thing plugged in to the USB port was a mouse. Tried all the ports, same message. Tried another mouse, same thing. Tried a thumb drive, and low and behold, 2 of the 3 USB ports worked. Tried a URL from MS which is supposed to help with this exact problem and possibly fix it: http://windows.microsoft.com/en-us/windows-vista/Tips-for-solving-problems-with-USB-devices
This didn't work.
Contacted HP support and they wanted me to restore back to a restore point as well as updating my BIOS. After searching the issue more extensively using Google, I found that several people said to do this:
Shut down the computer
Remove the power plug
Remove the battery
Put the battery back in
Power up the computer (without the power plug)
This forces a hard reset.
Almost as if by magic, the problem disappeared. A much simpler and less technical solution to the problem than what HP recommended!!!!

TS1369 Hello! I have an Ipod Shuffle 2nd Generation and it is not recognized by my Windows 8 based laptop. An error message of 'USB device not recognized' is shown. I have the latest ITunes version installed, and tested the dock in other pc's.

Hello!
I have a problem connecting my Ipod Shuffle 2nd generation to my Windows 8 based laptop. The computer doesn't recognize the Ipod and issues an error message saying 'USB device not recognized'. I tried uninstaling ITunes(latest version) and all other Apple software and reinstaling it back again, checked my USB hubs in the 'Device Manager' section of the Control Panel, you name it.
I could really use some help solving this.
I've turned to the troubleshooting section in Apple Support but it has nothing concerning situations in wich the device isn't even shown in the 'My Computer' folder.
Help a brother out, will you???

Found a solution in another forum http://en.kioskea.net/forum/affich-63733-ipod-not-detected-on-computer (a few posts down).
It was for an IPOD so you can see those details in the link.
Found how to reset a shuffle and inserted it into these instructions - did not have to follow his last steps.
- Turn off computer.
- Plug Shuffle into usb.
- Then you must reset your shuffle
To reset iPod shuffle:
Disconnect iPod shuffle from the computer (if connected).
Move the switch on the iPod shuffle to the OFF position. Note that when iPod shuffle is off, the green stripe by the switch is not visible
Disconnect iPod shuffle from the computer (if connected).
Move the switch on the iPod shuffle to the OFF position. Note that when iPod shuffle is off, the green stripe by the switch is not visible.
- Start computer and it should install the usb driver for the ipod automatically.
- Your i pod will say do not unplug so don't. then open itunes and it will be there.
I did not have to do these thing below – did not get error message and shuffle was displayed in Itunes. / LMc
Just remember to not only eject ipod from itunes but stop usb.
Go to the program icons near the clock and right click the usb icon and "safely remove hardware" will appear and click it.
Stop it and select "apple ipod".

USB Device Not Recognized issues

I have a Qosmio X505-Q860 and I've been getting the 'USB Device Not Recognized' error constantly for several months. I've never plugged anything into any of my USBs and the error is now causing a nice Blue Screen (which happened about 4 times yesterday within 1 hour). I've tried uninstalling the problem USB hub but it keeps telling me that it failed to uninstall (I'm on my administrator account when doing this). How in the world do I get rid of this so my computer stops crashing and driving me crazy!?
Edit: I should also mention that everything is up to date (I check often and checked just now).
"A stopped clock is still right twice a day."

I suggest trying another USB cable. If you are positive that your cable is not the issue then try resetting the iPod and booting into disk mode (Hold menu+select down until Apple logo appears. Then hold menu+play/pause down and the iPod will go into disk mode, see if the computer recognizes it then. If that works then their is either a software issue on the computer or a firmware issue. Worth trying to restore but backup all your iPod's files first!

"USB Device Not Recognized" Bubble/ Ipod won't connect to Windows

Whenever i connect my ipod to my computer the ipod goes to "do not disconnect" and a bubble pops up on my computer saying "USB DEvice Not Recognized" i have switched it to all of my usb ports and unplugged all usbs except for my mouse at the same time. this happens 95% of the time. my ipod does charge while connected and it has only connected to itunes once in the past 2 weeks. im not sure if it is itunes because it started around the time i updated to itunes 7. since it is a windows bubble though i think it is a windows or ipod problem and not itunes. i have a dell that isnt great but works fine.
thanks for any help.
... Go TTU!

Make that two idiots. My roommate got a Sansa and I decided to try out the cable. Nothing happened. Now suddenly my nano isn't recognized by my computer. I'm glad I read your post, now I can stop looking high and low for a solution. Until this happened it worked good as new.

I've tried eveything on the help website but nothing works! Can anyone help?!
patriot 3050 Windows XP

ok my question is do you have a mac or windows based laptop
here is why and what happened to my ipod mini
my ipod mini was connected to my macintosh charging while i was using my imac and it came up with a system update 10.4.3 i installed it and finished installing it and afterwards my apple wouldn't recongnize my ipod mini or even display it one the screen i found out by myself that when the apple update got to the end of the update it installed new hard drive drivers but also installed the drivers on the ipod mini which locked out the mini's internal hard drive and my mini then stop responding it would play music and charge but wouldn't connect to the computer
so what i did to fix it was this
i went into utilites in mac os x tiger or any version of os x has this and selected disk utility you will notice that the ipod will appesr in disk utility but not on the desktop this is due to a recent system update driver that isn't compatible with the internal drive on the ipod mini so in disk utility just select format the drive in a mac os partition standard works the best it will then format the ipod and the ipod will apear in the desktop again but not as a ipod let me explain when you format the ipod using the disk utility it formats and even erases the firmware of of the hard drive on the mini so when you are done formating the ipod run the ipod updater to reinstall the ipod's operating system and presto your ipod will now work again
warning: i don't know how to fix this on a ipod in windows so if this is a windows based laptop you need to find someone witha macintosh to do this with sorry

USB Device Not Recognized (&IPOD WILL NOT TURN ON)

I have had an iPod Shuffle G2 for 6 months now with no problems until today.
It went flat when I was at my friends place so when I got back to my mums I plugged it into my laptop and it told me "USB Device Not Recognized One of the USB devices attached to this computer has malfunctioned and windows does not recognize it" I thought there was just a prob with that port in my laptop, so I put it in the other one. So I though Ill wait until I get to my nan and pops and put it in there computer which is where I sync it. Same problem in both ports. Except on this computer the orange light is on but doesnt flash.
Now my iPod doesn't turn on at all..
Which is fantastic..

This did not work for me. I have a laptop that was running Windows XP, and it had no problems recognizing the iPod. I was having problems with XP, and rather then reinstall XP, I did a clean install of Vista. I did a settings transfer, so the new install of iTunes came already configured--I mention this since I don't know if it was a factor.
When I plugged in the iPod, I got the USB Device Not Recognized. The usbstor.inf file did not fix the problem. However, the solution at http://www.winvistabeta.com/groups/275128/ipod-usb-device-not-recognized/message .aspx did fix the problem. Do this:
Reset the iPod:
1. Unplug the iPod.
2. Turn the hold switch to HOLD and then back to off.
3. Hold the Center and Menu buttons for 6 seconds until you get the Apple logo when you release them.
4. Plug in the iPod. It should now be recognized.
This worked fine for me the first time. Thanks! Jack

2G Nano-USB Device Not Recognized message

2G Nano has been sitting for months. Decided to use it as a backup. When connected to computer (tried on 4 different computers running iTunes) I get a "USB Device Not Recognized" message. It shows up in "Device Manager" as an "Unknown USB Device" not an "iPod". Have performed the required 5 Rs and it still will not work. Any help would be greatly appreciated!
