My usb keyboard is no longer recognized

the update hung trying to find a bluetooth keyboard
had to use this bt keyboard
usb mouse no longer works plugged in to the usb keyboard
usb mouse works fine plugged in directly to my Mac mini 2014
HELP

Yes, to a blue tooth mouse only. I have tried disabling the blue tooth connection, but when i restart my computer it automatically connects again.
I got the keyboard to start working again now by pressing all the keys one by one (in order to discharge them, read that somewhere). I helped. But how annoying is that?!

My usb keyboard is no longer detected after the power was switched off

I sometimes relocate my Imac to another office and after the power has been switched off the computer no longer detects my usb keyboard.
This had happened several times now and sometimes it all of a sudden starts working again after a couple of hours (but it doesn't now).
The computer keeps searching for a wireless keyboard which I don't have. I have tried everything from switching off power again to reboothing, but nothing works. I have checked all USB ports with other devices and they all work. The problem is not the keyboard itself, because it does work when I plug it in to my MacBook.
Anyone recognize this?

Apple USB keyboard is not being recognized with my iMac, what do I do?

When I startup my computer I am prompted with the 'there isn't a keyboard connected' message. I'm using an apple wired USB keyboard, it was working perfectly fine yesterday and it appears to still be operational as I can charge my iPhone from it.
I've tried restarting, using different ports, removing other USB devices, but haven't had any luck. I can only access my guest account as my main is password protected.
I don't know what to do, can someone please help?
Thanks

USB MIDI controller no longer recognized by mac (not even in System Information).

Hello!
I have an M-Audio Keystation 49e that I have been using with my MBP (early 2008 model) for a few years with absolutely zero problems ever. I recently bought a very generic Chinese MIDI interface ("Sanoxy" brand) to go between my full-size Yamaha and mac so that performances of parts into logic would be on weighted keys and such.
For a while I used both the MIDI interface with the Yamaha and the little 49-key MIDI controller (via USB and also powered by the USB) with no problems. I believe this problem occurred when I tried to use both the MIDI interface and MIDI controller on one USB port using a Targus external number pad (unpowered) that has two USB ports on it (bad idea I'm sure). I did this because my MBP only has two USB ports on it and I was using the other for my audio interface.
I have reset PRAM more than a couple times, reset SMC, cleaned caches (even though this could be done more thouroughly maybe with a recommended program besides Cocktail - trial is expired), even replaced AppleMIDIUSBDriver.plugin from my parents iMac which the MIDI controller still works on. All this and nothing. The keyboard is not recognized as even being plugged into the USB port on System Information even though the lights are on, much less AMS.
Any other information you need I'd be happy to let you know.
Super thanks!

Installed itunes - usb flash drive no longer recognized

hi,
I installed itunes, loaded up the ipod with music, and now my computer will no longer read the files off my usb flash drive. the computer sees the "mass storage device" when I plug my drive in, but the volume/files are not coming up.
any suggestions?
thank you!

Are you sure the files are still on your Flash drive.? Can you locate them in a folder on you flash drive just by going to the iTunes\iTunes Music folder and viewing the array of folders? If they are there, go back to the iTunes icon on the desktop, bring up the list of tunes, highlight them all, delete them, and go back to the Flash drive, highlight all the folders, drag them over to your blank iTunes screen and drop them. You won't get any indication anything is happening right away but they are reloading. For some reason iTunes cannot update itself with the correct pathways.
Hope this helps, Dave.

USB Keyboard not working after running Monolingual

Okay, I'm not a Mac person and should have known that I was going to mess up my mother's iMac, but here it is -
In an attempt to improve the mac's performance I performed all of the actions described in the following article: 11 Ways to Optimize your Mac's Performance ( http://lowendmac.com/eubanks/07/0312.html ). Basically, I cleaned up files and 'other' system preferences. Things seemed to be fine and the computer did run much better. However, after running Monolingual and deleting what I understood to be 'unnecessary' PowerPC files the standard USB keyboard is no longer working.
I've tried to search for various remedies, but have come to a dead end. So I'm left with reinstalling the Snow Leopard OS (I think it is 10.6.8?) BUT I can't because it is asking to input the account password (which I know) to make the change and I can't figure how to do that when the keyboard not working.
Any help would be great!
*feeling like a bone head*

How are you trying to reinstall Snow Leopard? If you're booting from the Snow Leopard or iMac Install DVD that came with the system then that should eliminate any of the issues you may or may not have caused when you deleted did the clean up work on your mom's system.
I suggest trying the following:
0) Verify that the caps lock key is off. It can make inputting passwords difficult if you don't realize it is ON.
1) Reset the PRAM by restarting the system then quickly press the command-option-P-R keys before the gray screen appears. Wait until you hear the computer restarts two times as indicated by the startup chime. For more info refer to http://support.apple.com/kb/ht1379.
2) If the issue persists after the PRAM reset then boot from the Snow Leopard or iMac Install DVD, whichever you have. Once you see the menu asking you to choose a language try using the arrow keys on the keyboard to move the language choice selection. If the arrow keys are working at this point it indicates your keyboard is at least partially functional. Go ahead and select the language then proceed to step 3.
3) Once the next screen appears move the cursor up to the menu bar area and pull down the Utilities menu. Select the 'Terminal' application. Once the Terminal application launches try typing the various keys on the keyboard and check to see if the correct characters are displayed. Please let us know if you detect any errors. If there are no errors then you should be able to quit the Terminal application and proceed with reintstalling the OS.

Just installed OS X Yosemite Version 10.10.2 - My Apple USB Keyboard now refuses to work. I'm using a iMac Retina5K 27inch Late 2014 - any suggestions?

Hi I've just installed OS X Yosemite Version 10.10.2 - My Apple USB Keyboard will no longer work. Any suggestions? (iMac Retina 5K, 27inch Late 2014) Thanks.

Hi, thanks for the assist. Looks like there is a glitch in the new software, as I did as you suggested, removed other USB devices, powered off. Then plugged in the keyboard - re started and hey presto it worked. Thanks v.m.

After updating to 5.0.1 my keyboard dock no longer works.

After updating, the keyboard is no longer recognized. It shows that it is plugged in (charging) but keys won't respond.

Are the songs that you are trying to play grayed out in your playlists?
I had this problem after upgrading to iOS 5, and I found that deleting all the songs from my device and re-syncing them fixed the problem.
To do this:
1. Attach your iOS device (either using the cable or to the same wi-fi network if using iTunes Wi-Fi Sync).
2. Open iTunes, and click on your iOS device.
3. Click on the Music tab.
4. Uncheck the "Sync Music" checkbox at the top.
5. When asked, click "Don't Sync Music".
6. Sync the iOS device. Your songs will be removed from the device.
7. Check the "Sync Music" checkbox at the top once again.
8. Sync the iOS device again, and your songs will be re-added.
I don't know why the upgrade made some songs unreadable, but the resync fixed the problem for me (I had to do this for each of my iOS devices after upgrading them all to iOS 5). Fortunately, I only had 1,000 songs, so the resync didn't take forever.
Hope this helps!

Adb keyboard to usb keyboard

I have an old powermac 9500 running os9, and would like to use a usb keyboard. is there an adaptor, or a usb card i can install in the powermac? I have an adaptor to go from usb to adb, but cannot find one that goes the other way.

These are USB 2.0 cards, but they will work as USB 1.1 in OS 9.x. Best bet is any card with a NEC PD720100 or PD720101 chipset
All of these Cards are NEC chipset based
Adaptec 3100LP
BAFO BF-460
Belkin F5U220
GWC UC-160
IOGear GIC250U & GIC251U
Keyspan U2PCI-5
O'toLink U2-C2A, U2-C2B, U2-P20N & U2-P50
Ratoc PCIU5
USBWholesale UII-PCIP
I use an IOGear GIC251U 5-port USB PCI card in my G4. Prior to getting a USB 2.0 card, I used a Belkin F5U005 2-port USB (1.1) PCI card (with OS 9) for more USB ports.
When you get a USB card you may have to reinstall OS 9. When OS 9 is initially installed, it usually doesn't install the USB software if a USB card is not installed/detected. So install the card & then do the reinstall.
Don gave you some good advice about keeping the ADB keyboard. With the ADB keyboard, the keyboard is recognized instantly whe the Mac is powered up. However, the USB keyboard will not be recognized until all of the system software is activated. You'll need to use the ADB keyboard for zapping PRAM, booting from a CD, etc.

USB keyboards and Live CDs - an inconsistency that is driving me nuts

Hello. I tried to boot up my iMac from the LINUX FROM SCRATCH LiveCD to see if I could install that system. When I tried to, it got to the "boot:" prompt but my USB keyboard would not get recognized whenever I tried to boot (yes, I rebooted a few times). I don't have rEFIt on, and Boot Camp didn't partition yet - but with rEFIt and Boot Camp the keyboard would work SOME of the time. Does anyone know what's going on? I thought Apple EFI handled this when it came down to BIOS emulation.
PS - Has anyone ever tried to boot up the Plan 9 from Bell Labs install CD from the iMac? If so, is the fact that it froze after the second text line related to this?

Hello? This is a problem for me! Does anyone have any information?

Matias Keyboard No Longer Recognized by Leopard PB G4 But By Tiger

In February I took a month long trip with my Leopard-based PB G4 and Matias folding USB Keyboard. Everything worked together fine until after my return in early March when I noticed that the keyboard no longer worked with my laptop. Since my return I have received the normal Apple-push updates to my system. I tested the keyboard on my daughter's Dell laptop and it worked fine. I checked the keyboard with a friend's Leopard-based MacBook but to no avail. I called Apple Tech support and they initially informed me that it was not a Leopard issue because all third-party hardware should be automatically recognized by the computer. They also walked me through doing a reset of the computer to bring it back to original operating configuration. I contacted Matias who had their senior engineer look into the USB-capable keyboard and said they are not aware of any problems between the keyboard and Leopard. They also did not have a patch to push to me to get it connecting again but I will be keeping in contact with them about this. I brought my computer into an Apple store only to have them confirm that the keyboard is not being recognized by the USB drives, but there was nothing else they could do for me. I had the USB drives checked out a seperate computer store authorized to work on Apple computers and they both worked fine. At home, nothing that runs through the USB ports is NOT being recognized, everything works fine. While at the same computer store I found an older iMac using Tiger (10.4.7) and successfully tested it there after going through the normal syncing process. But on NONE of their Leopard-based Macs did it work which leads me to believe it is somehow related to either Leopard or an update everyone has received. While the folding keyboard may have only cost $99, I am hesitant to spend $75 for a service call at an authorized repair shop, and they advise me to re-consider having to visit them. Only because it is a great travel accessory for me to work on longer papers and projects rather than the laptop's own keyboard do I want to get this one working with my computer rather than buying another one. So my questions are, 1) how do I individually disable the updates received since March to determine which one is affecting recognition of the keyboard, and 2) why would the keyboard continue to work with Tiger and Dell but not on any Leopard-based Mac? Apple Tech's comments are primarily "it's not a Leopard issue, I should go somewhere else" to get it checked out.
The updates since March are:
Battery Update 1.4
Airport Client Update 2009-001
Airport Utility 5.4.1
Time Capsule and Airport Base Station Firmware Update 7.4.1
Front Row 2.1.7
iPhoto 8.0.2 Update
iLife Support 9.0.2
iWeb 3.0.1
iWork 09 9.0.1
iTunes 8.1.1 for Mac
iMovie 8.0.2
Server Admin Tools 10.5.6v1.1
Any assistance from the community would be greatly appreciated.

Hi, Richard. In answer to your first question, you don't and can't disable the updates you've installed unless you use Time Machine to back up your Powerbook's hard drive. If you do, you can step back in time to just before the last software update, and restore that configuration to your hard drive. Then repeat the process for each previous update. This will be ungodly time-consuming.
If you don't use Time Machine, all you can do is reinstall everything from scratch up to the last point at which you're sure your keyboard was working properly, and then add the subsequently-released updates one at a time until you discover the one that renders the keyboard useless. Then reinstall everything all over again from scratch except that one update.
If I were you and were facing this incredibly tedious diagnostic process, I'd either return to running Tiger or buy a different keyboard.

USB-MIDI no longer recognized by applications

I have been using my mac on stage for quite some time. Together with Kontakt and a USB-keyboard, it has worked well. Until recently. I do not know what I have done that could have broken it, probably it's the latest Mountain Lion update.
The USB-keyboard (currently a KAWAI stage piano) is still recognized by AUDIO-MIDI-Setup, but it is no longer available in the KONTAKT setup menu. I sometimes use MIDI-Pipe (and it work well until recently). Now, within MIDI-Pipe, I can still select USB-MIDI as input, but MIDI-Pipe does not receive any MIDI signals.
I was able to solve the situation by setting up a new user. Within the new user, MIDI (and MIDI-Pipe and Kontakt) worked well. This was two days ago. Yesterday I had a gig and, after starting my MacBook on the stage, MIDI was gone again. I was able to solve the problem by setting up yet another user, but that was no fun with the whole audience watching...
The second breaking of MIDI was particularly mysterious for me since I have done nothing in between except shutting down the Mac, rebooting it, logging with my old account, doing E-mail, shutting down the Mac and recharge it.
Needless to say, this situation can't go on. I need to rely on my equipment! Setting up new users on stage is not an option...
Any suggestions are greatly appreciated!

I've just updated to 10.8.3 and the problem is still there.
Currently I have one user account under which my USB keyboard works as it should, and I have two other accounts on which the keyboard still doesn't work. Please don't tell me to simply use the one account that works, because the other two accounts initially worked, too, and I do not want to risk to once again loose MIDI functionality while I am on stage!
I've found one difference in Audio-MIDI-Setup / MIDI-Studio between those accounts that don't work and the one account that works: In those accounts that don't work, there is only one triangle below the USB-MIDI symbol, indicating unidirectional (output) functionality, whereas under the working account, I see two triangles (input and output). Furthermore, under the problematic accounts, Audio-MIDI-Setup keeps crashing.
****! My MAC is my equipment on stage. I need it to work!

USB devices all of a sudden no longer recognized in windows 7

Hi,
I am using a HP Pavilion Simline s5550nl edition with windows 7 home premium (64-bit) since 1.5 years. Never had any problems until 3 days ago. Since 3 days suddenly some new devices, already plugged-in devices and previously used devices are no longer recognized (USB-device not recognized-error after plug-in).
I used an USB-mouse, USB-keyboard, Smartcard-reader, Sony Story 1.5TB External HDD, USB WebCam. They al worked fine.
3 Days ago I bought a WD Elements 2 TB External HDD. After plugging in, it was not recognized at first. Replugging it in it was recognized, but trying to open the drive in Explorer, it gave a not-formatted-error (while the disk should have been pre-formatted for Windows 7). However, i tried to format the disk, but it could not reach it any more. After rebooting the system the WD elements HDD gave the USB-device-not-recognized-error, using all other USB-ports didn't change that. In fact my Sony External HDD was no longer reachable either. Unplugging and replugging it in gave the same USB-device-not-recognized-error. Trying previously flawless working USB-devices all gave the same USB-device-not-recognized-errors (USB-flash disk 4GB, External HDD 2.5inch 160GB, USB-/card reader HUB, iPhone).
I then tried to connect my Sony and WD external HDD on my other computer with windows XP SP3. They were recognized within seconds and working fine (also the WD elements External HDD indeed turned out to be pre-formatted).
Strangely enough my USB-mouse, USB-keyboard and smartcard-reader kept being recognized at plug-in. Furthermore, my printers (connected over LAN) and NAS (connected over LAN) were usable without any problem. I did not encounter any other problems in functionality of windows. I then thought it might be a corrupted general USB-driver for mass-storage or something, so I started to google this problem. Things I have done so far (before each step I unplugged all USB-devices, rebooted and reconnected the devices):
- Turning computer off, unplug power-cable for 2 minutes, reboot.
- Updating BIOS to version 6.04 (was running version 6.02).
- Uninstalling all USB-devices/mainhubs etc in devicemanagement, automatic reinstallation at restart.
- Try installing newer USB-drivers for mainhubs, messages the installed drivers are already the latest.
- Uninstalling all 'hidden' USB-devices.
- Trying to go back to configuration of 1 day ago (maximum i could go back), resulted in an error that the file might be corrupted.
- Turning computer off, unplug power-cable overnight, reboot.
- Running HP-systemdiagnostics: all passed.
- Running Norman anti-virus scan (latest update): no infection.
- Again uninstalling all USB-devices/mainhubs etc, automatic reinstallation at restart.
I also noticed that during the night before this malfunction appeared (so actually several hours), on january 20th, an automated microsoft critical update was installed (some anti-spyware definition update). I am now thinking it might still be a driver-problem of some sort of general USB-mass storage driver or due to this microsoft update or maybe some clever virus.
I no ordered a Recovery disk (never had to use one, so did not jet own one), to recover windows and if that doesn't help reinstall it. However I hope that anyone can bring up a solution that I am overlooking?
D. Berks

OK, meanwhile I found that only uninstalling the USB2-driver enables the USB-ports again. Uninstalling it makes al devices recognizable, whil reintsalling it immediately makes all USB-devices unrecognizable.
I tried updating the driver to the latest version, deleting it (after reboot an automated reinstall is triggered), but nothing helps. As if soething that stays in the system makes USB2 to corrupt USB-channeling or something.
I strongly believe that it has something to do with the windows-update, but I can nowhere as a question about it to microsoft (will cost 70 euro's!).
Does anybody knows what this could be? Or better: knows of a solution?
Tanks,
D. Berks

My old Intel-Based iMac is no longer recognizing USB wired input devices; it only recognizes Bluetooth. What happened?

My friend's old Intel-Based iMac is no longer recognizing USB-wired input devices (Kensington TrackBall, Logitech Mouse) plugged into any USB slot at the back of the computer.
They were working before and for many years.
All of a sudden, A pop up window came up. IT said no Bluetooth mice could be found. We don't know what set off that window to pop up and look for a WL mouse. It never has before in the 5 or more years my friend has been using this computer.
I supplied a wireless Apple mouse and his is back running again.
But want to know why his USB-input devices (Except his keyboard) are not being recognized. He would prefer to use his Trackpad (Wired), but can't find anything in SYstem PReferences to allow that. The computer only seems to want a Bluetooth input device.
Anyone have an idea what happened and if this can be reversed?
I think he is still running Mac OS X 10.5.8.

Hi Carol, lets try this...
reset FW bus, same goes for USB reset...
Reset the Firewire bus
If your Firewire or USB isn't recognizing any device. A solution which has worked for some whose hard drive became invisible in 10.4 was simply to follow these four steps to reset the Firewire/USB bus:
1. Shut the machine down.
2. UNPLUG the power lead to the computer and any firewire/USB drive/devices.
3. leave it for 10 minutes.
4. Connect back up and reboot.
