Sidebar not recognizing USB device but keyboard OK

USB can not be seen on the sideboard. I am so angry I can't see straight and having a GD brain tumor doesn't help because my processes are slow and it's hard to understand… So I did a CLEAN install. When I reboot with option I can see and reinstall lion like I have 3 times with my device. When I go to system profiler it sees the FING simpletec device. I mean what a bug. Mac was supporting MACKEEPER for a spell so I thought this would be a GREAT program and then they took it down. I, naturally, have done EVERY EXPLICIT THING to fix this problem. Adding a user, still didn't see it. I don't think there's an answer to this problem tonight because it BLOWS MY FING MIND and there is no answer. I wanted to use my terminal to get into the system and hopefully resove this issue. I did install MACKEEPER because it was in the F app store and now I did EVERYTHING to remove it but I have a feeling they've done something to circumvent the yoinking of their crap off the system. Switched the USB Storage1.3.5 2.dmg. Checked for drivers. Entered my stupid user name and pass 100 times on this site which is ludicurious. EVERYTHING. I've looked and looked and looked and well, it can't be such an easy solution. It recognizes my keyboard but not one other fing thing. Not my camera... I just can't get over it. I can't *wait* to get a new computer because the next one is going to be a PC because after 13 years of supporting Apple I'm just not feeling the love and I've lived with so much aggravation, lost out developing my craft because the software was not available so… I've just about had it. I've looked for programs… ugh. change

I had the same problem. Try this. If you've recently done the uninstall/reinstall software phase, don't bother again. The problem, at least for me was NOT the computer, it was the nano.
Reset the nano. Push the hold button till you see orange and then back again, lay it on the table and press the center of the circle (select) and the Menu at the same time, hold it 6 to 10 seconds until you see the apple.
Then, plug your cable into the computer first, wait a minute, then plug it into the apple and WAIT (if you are so inclined, this is a good time to say a quick prayer).
It worked for me, hope it works for you.

Solution for XP not recognizing USB device ...

Hope this helps ... here's how I got my XP machine to recognize the IPod.
1) Un-installed all the software (not sure if this was critical, but it is part of the order of events I followed).
2) Next, I unplugged the IPod from my desktop and unplugged the USB cable from the IPod. Then --- I plugged the USB cable into my desktop FIRST and then plugged it into the IPod.
TBy plugging in the USB to the desktop first, I seemed to jiggle XP into recognizing the IPod. Now I can just connect and disconnect the IPod like any other USB device.

Macbook Pro (Retina) not recognizing USB devices?

I'm having some odd troubles with my Macbook Pro that I haven't had before.
I have an iLok that's not being recognized by the computer so I can't start up Pro Tools; however, when I tested the iLok on my sister's Macbook Air, it was recognized fine on iLok.com's tests (that also proved not to work with my Macbook).
I also have an Anker 4 port USB hub (not external-powered) that was running my Intellimouse by Microsoft perfectly fine until I shut down my computer last night and turned it on this morning to try it out.
Strangely, the mouse works directly on the USB port, but won't when attached to the hub anymore. The hub worked with another device but my ILok doesn't get recognized on my Macbook through it either (or any of the 2 ports directly either).
I tried an SMC reset (ctrl+shift+opn+power) and a PRAM reset (cmd+opn+P+R on power-on), but everything is still haywire.
I might have installed some updates last night, I can't exactly remember but vaguely can recollect a dialog box from the App Store.
What can I do to really resolve this issue? Is anybody else having something of this sort happening?

Just wondering if you ever found a solution. My mbp retina is not finding my iLok 1. No green light. Max 5 won't authorize.

USB Device Not Recognized - USB device attached has malfunctioned & Windows does not recognize it

I have an HP Pavilion dv4 Notebook running Windows 7 Home Premium and the USB ports worked fine for an HP deskjet printer and an older Casio digital camera. Then one day, the laptop decided not to recognize the Casio digital camera and gave the error message "USB Device Not Recognized" and also indicated that the device attached to the computer has malfunctioned. This prompted me to buy a new Canon digital camera. Well, a new camera did not fix the problem. Now, anything connected to either of the 2 USB ports will not be recognized by my laptop. Help! I'm at a loss to figure this out. I've tried the suggested Microsoft help below:
Suggestion 1: For the issue with USB devices, uninstall and re-install all the USB controllers. This lets the controllers recover the USB port from its unresponsive condition.
The USB controllers represent the USB ports in Device Manager.
a. Click Start, type device manager in the Start search box and hit Enter.
b. Expand Universal Serial Bus controllers.
Note: You might have to scroll down the list to find this item.
c. Right-click the first USB controller under Universal Serial Bus controllers, and then click Uninstall to remove it.
d. Repeat the above step for each USB controller that is listed under Universal Serial Bus controllers.
e. Restart the computer. After the computer starts, Windows will automatically scan for hardware changes and reinstall all the USB controllers that you uninstalled.
f. Check the USB device to see whether it is working.
This did not correct the problem. Then from device manager, I tried updating drivers on all the USB controllers and root hubs. While some may have received downloaded software updates, it still did not correct the USB device not recognized problem after restarting the computer. I'm hoping someone knows of the fix to this situation and can pass it along to me. Thanks for reading and posting any help.

Hey 655micha,
I'm sorry you're having an issue with a USB device. Do you get an error window that pops up? If so what does it say? Have you checked Device Manager? Is is just one device that isn't working? Has it ever worked before? Is it just one USB port in particular that isn't recognizing devices?
What model do you have? Here are the steps to find your product number. FN + ESC is the easiest way to find that information.

Mac mini not recognizing USB mouse and keyboard upon boot

hey guys, i have a 2.4GHz mid-2010 mac mini with 2GB of ram, running 10.6.8 with all software up to date. this computer was purchased about two months ago. when i boot the computer, it does not recognize the USB keyboard or mouse though each is powered by the USB ports. oddly enough, after waiting for about 5-10 minutes, the keyboard and mouse magically begin to work normally and anything i did while they were both "frozen" happens all at once.
any ideas? i've done an SMC reset to no avail, tried other USB keyboards/mice, and i am unable to reset the PRAM because the keyboard doesn't work while the computer is booting. thanks in advance.

yeah, i did all of that; former tech here. i might just nuke it and start over, i wanted to post and see if anyone had the same issue. bizarre thing is that it actually DOES recognise the peripherals and they start to work after about 5-10 minutes, 'remembering' everything i did while it was semi-frozen. i.e. the mouse starts clicking everything i clicked, the keyboard logs all keys pressed, and everything happens all at once as it 'wakes up'. haha. one of my co-workers told me that the girl before me who was using this mini wasn't too bright and had that whole macdefender thing happen so it might be some residual leftover from that.
it also takes a pretty long time to boot so i'm suspecting it may or may not be something hardware-related.
thanks for your response!

My MacBook is not recognizing USB drives, but it recognizes my iPhone. Can someone assist me? Thank you.

I am trying to get my mac book to recognize the thumb drive. When I go into Disk Utilities it does not show up there either. I have no problem syncing my iPhone to it so I do not think the USB drives are bad. Can someone help me out? Thanks!

I am getting the same issue with my MacBook Pro. If I go for a long peroid of time without restarting it starts to 'forget' USB sockets. First one stopped wortking and then the other. I restarted and they both beagan working fine again. Try giving that a go - I know it's an obvious option but it worked for me.
Otherwise check the file system on the thumb drive - is it Mac compatible? FAT 32 for example? Does it show up on other computers?

On the moment that I connect the Iphone 5 on Windows 8, it is not recognized by Itunes, but actually it appears as a usual USB cable, or as a camera. And then I can't synchronize the Iphone 5 with Itunes. So, what do i do?

Hi pedro109,
If your iPhone is recognized by the computer, but not seen by iTunes, you may need to restart the Apple Mobile Device Service, as described in this article -
How to restart the Apple Mobile Device Service (AMDS) on Windows
http://support.apple.com/kb/TS1567
Once iTunes recognizes the iPhone you should be able to sync it with iTunes. See this article
iTunes 11 for Windows: Sync contacts, calendars, and other info with iPod, iPhone, or iPad
http://support.apple.com/kb/PH12317
Thanks for using Apple Support Communities.
Best,

Hey corky60,
I'd go ahead and give the following troubleshooting steps a shot:
1. Try the iPod troubleshooting assistant:
2. Restart the iPod Service
3. Restart the Apple Mobile Device Service
4. Empty your Temp directory and restart
5. Verify that the Apple Mobile Device USB Driver is installed
6. Change your iPod's drive letter
7. Remove and reinstall iTunes
8. Disable conflicting System Services and Startup Items
9. Update, Reconfigure, Disable, or Remove Security Software
10. Deleting damaged or incorrect registry keys
You can read more about each step in detail in this article:
iPod: Appears in Windows but not in iTunes
http://support.apple.com/kb/TS1363
I'd start at the top and work through the steps until iTunes recognizes your iPod nano.
Take care,
David

USB is not recognizing the device and giving error 10

My PC USB is not recognizing the device (iphone) and giving error 10.. The USb is malfunctioning but ipod is getting connected easliy

Try DFU Mode Restore. Open iTunes on computer. Connect iPhone to computer with USB cable. Hold both Home and Power button, after exactly 10 seconds release the Power Button, keep holding the Home button until iTunes recognizes iPhone in Recovery Mode, usually about 20 seconds time. If the iPhone screen is black, blank this is DFU Mode. Click the Restore button of iTunes.

Yesterday, I plugged in my iPod to sync, and my computer opened iPhoto as it always does. It obviously recognized the device, but the iPod sis not appear in iTunes and I therefore could not sync it. Is there a setting I may have accidentally turned off?

and my computer opened iPhoto as it always does. It obviously recognized the device, but the iPod sis not appear in iTunes and I therefore could not sync it. Is there some setting I may have accidentally turned off?
Also, today, there seems to be no sound coming through either my internal speakers or my headphones, and not just in iTunes. I doubt these two problems are related, but perhaps there is something beyond coincidence and an old computer?

For sound issues check System Preferences > Sound
Make sure the Mute button is not selected.

i have installed updated version of itunes but it is not recognizing my devices can anyone help

Many thanks.
That suggests that another application has stashed old QuickTime componentry in your system files.
So just in case we'll go looking for older QuickTime componentry in the most common locations for it to be stashed.
First we'll need to change some view settings.
In your Start menu, open Computer.
In your Organise menu, select Folder Options.
In the View tab, make sure that "Show hidden files and folders" is selected, and Hide extensions for known file types is unchecked.
Click OK.
Now in Computer, open your C:\ drive (or whichever drive you have your operating system installed on).
Open the "Windows" folder.
If you have a 32-bit version of Windows, open the "System32" folder.
If you have a 64-bit version of Windows, open the "SysWOW64" folder.
What files and folders can you see in there with QuickTime in the title? (In a standard installation of Quicktime you should be seeing precisely two files... QuickTime.qts and QuickTimeVR.qtx ... and no QuickTime folders whatsoever.)

I also live in the United States so redownloading shouldn't be a problem.

My new mac mini does not see usb drives, but in hardware info the usb is visible

my new mac mini does not see usb drives, but in hardware info the usb is visible
i'tried several usb flash drives even brand new ones, they are visible onder hardware info but they are not on the desktop nor in the finder.
what is wrong and doe anyone has a solution ?

It does not show up in disk utility, its only visible through systeminformation.
When you plug in the USB flash drive and then refresh systeminformation it becomes visible.
To remove it I shut down the computer because I cannot eject the USB device anywhere.
After starting up again when I have removed the flash drive it has gone from the systeminfo USB list.
By the way my USB mouse and keyboard are working fine, I also changed ports of these and they still keep on working so I don't think the USB ports are defect.
I guess it some kind software problem, and because I'm new to Apple I do not know much about it how to solve this.

My dvd drive not recognized in device manager,getting the yellow explanation mark.

my dvd drive not recognized in device manager,getting the yellow explanation mark. Tried uninstallingdevice drive and scanning for new hardware. scanned for updates, etc. I getting no results. The laptop is a Pavilion DV5. Thanks

Hi,
It could be that the drive has a Hardware issue, but try the following.
From the Start Menu, open All Programs, open Accessories, right click the Command Prompt and select 'Run as Administrator'. In to the prompt type the following command and hit enter.
sfc /scannow ( note that there is a space between sfc and the / )
Let the process complete, then type exit and hit enter.
Next, open Device Manager, right click the DVD drive and select Uninstall. When this has completed, restart the notebook and let Windows rediscover the device and check.
Regards,
DP-K

Audio CD not recognized with Mini but reads with Macbook?

Error message saying Audio CD not recognized with Mini but reads with Macbook pro. Both machines are using the same Samsung external usb dvd/cd player.
I've tried rebooting the mini, cleaning the disk, unplugging the drive and the Mini still won't recognize the CD's (it's a 3 cd set and all 3 disks aren't working on the Mini.
When I use the same disks and drive with my Macbook Pro everything works fine.
Any suggestions?

Hi Jay,
Certainly a strange one!?
Are these commercial or self made Discs?
Have you tried CD/DVD sharing on the MBP & see if the Mini can read them in the MBP?
