USB devices not showing up in 10.6.5 update

I use two pioneer cdj 400 which hook up via USB to the mac, they use to work fine with my USB hub in 6.4 but since the update to 6.5, only one show up in the system profiler in the USB hub as cdj 400 or composite device, the 2nd one also show up as composite device.
What's going on?

Apple isn't here.

No USB devices are showing in finder although I have a thumb drive, a card reader and a Seagate external drive plugged in. When I unplug one, I get a message that I didn't eject the disk properly.

We have already replace the DVD Drive and the board for the fault of not recognising disc but the problem of the USB error message coming up on the screen still remains, we tried disconnecting the USB board from the front but the message still comes up on the screen.
Any help would be much appreciated..

Same problem here, wondering if it has been caused by a recent OAD ?

Had the same issue. Tried everything that was posted for troubleshooting bye apple and on the discussions.
Finally, tried something that solved it and it works flawlessly now. I changed my wireless router.
I was using my ISP's supplied ZyXEL PN660 ADLS2+ with Wireless N. Swtiched to an older Linksys WRT160N and it is working beautifully now.
Take a look at your router, make sure the firmware is up to date, and that UPnP is enabled, and if all is correct, and you have done everything else, try another Wireless router if you can.

I've run diagnostics. Can't find device. I've tried resetting. The toggle has been turned on and off.

Cable works fine on my other iPod. Reset by pressing menu and center button together for 6-10 seconds. Left it to charge for many hours. Started acting up while running. Suddenly the music stopped playing but my Nike + was still working for the rest of my run. Took it straight it home and plugged it in to the wall to recharge since the battery was fairly low. Looked like it recharged ok but then screen went blank and now does it not show up on iTunes, does not seem to recharge by the wall charger (apple wall charger plugged into a surge protector in India). I have turned the hold switch off and on many times.
Sounds like a repair issue, which is not easy to do in India :(

Lion 10.7.2 / iTunes 10.5 - Devices not showing up

Any device attached via USB is not showing up in iTunes. I have the following ipad2, iphone 3gs and itouch (latest gen)
USB connections are working as ipad2 and itouch devices show up in iPhoto.
I have a Mac Pro Early 2008 version.
I've tried the following:
1) switching USB ports on my Mac Pro
2) rebooting Mac Pro leaving devices powered on
3) rebooting devices leaving Mac Pro on
4) turning everything off, and booting Mac Pro first. waiting 2minutes and then powering on ipad2, iphone, itouch
Nothing seems to work. Hoping someone else is stuck in the same spot or can advise next steps.
Thanks,
Nick

So far the only solution I have been able to find has been launching the recovery partition and running disk repair. That will fix the problem until you trigger it again. Fortunately, or unfortunately, I have pinpointed what triggers it on my computer.
Seems to be a flaw in keychain access. When Safari's connection times out due to an expired certificate (common in university networks that require a log in every few hours), the security settings freak out and effectively shut down safari's ability to do anything. The fact that it attacks KeyChain access and iPhoto and more is just a really big system wide glitch. Here's the run down:

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!

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

"USB Device not Recognized" when shuffle is plugged into computer

Everytime I plug my shuffle into my Dell laptop it comes up with the message "USB device not recognized". The shuffle doesn't show up in my computer or itunes. I've done some of things that it says to try, but I'd really like to get this fixed and get my shuffle working. Typically when I plug it in, it blinks once, yellow/orange, and then no more, and the notice comes up on the computer screen. If this makes a difference, the shuffle worked fine until last summer when my hard drive crashed. Upon installing a new hard drive, the shuffle began to not work/sync with my computer as it had been before. Any suggestions on how to get my shuffle working again? Much appreciated!

Well start with these articles and see if that gets you anywhere...

"USB Device Not Recognized" error when I connect iPod to my PC

I have a brand new 5th gen (I think) iPod.
I have been able to connect it successfully to my home laptop, download music to it and play it so I know the iPod works per se and the cable is ok too.
Now at work (where tons of my music is) when I connect it to my PC here and I get a "USB Device Not Recognized" error pops up from my taskbar. When I click on the message it pops up a "USB Device Not Recognized" window which displays a list of USB ports, and shows "Unknown Device" for the one where the iPod is connected.
I think its probably USB1.something as opposed to USB2.0 but from what I understand that shouldn't matter.
Can anyone suggest anything ?
I've tried the 5R's as far as I can, and I read through this thread:
http://discussions.apple.com/thread.jspa?threadID=500559&tstart=15
but there didn't seem to be anything conclusive.
Thanks for any help,
Jill

First make sure the latest iTUnes is installed on this work PC, IF your allowed to install things on it, the latest iTunes version is 6.0.4.2 and can be downloaded from the apple site (Hit iPod+iTunes tab at the very top of this web page)
Another thing is what version of windows is the work PC? Is it windows XP Windows 2000 Or windows Me 98? iTunes will only run on XP and 2000

USB device not recognized win7 iPod Touch 1g

My computer will not recognize my 1st Gen Ipod Touch 8gb when I plug it into my USB port. I get a message USB Device Not Recognized. I've tried everything from resetting the iPod, uninstalling and reinstalling iTunes and all other Apple related programs, to fiddling with the settings in my Device Manager. It will only recognize it as an Unknown Device, not even an Apple device.
What should I do? I just got this thing through a trade, it's clean, wifi works fine, in great condition. I just don't know what to do! It won't show up in iTunes at all, won't show up as a mass storage device, nothing. I am running Windows 7. I've also tried using different cords, different usb ports, and another computer. None of that made a difference.

Itouch - USB device not recognized and Itouch now no longer works

I'm now on my 3rd Itouch since December all due to the same problem. All seemed to be going well with my 3rd replacement Itouch. Having loaded most of my cd collection into ITunes the night before I was going on holiday I synced my Itouch. Some sort of automatic download took place I think from Microsoft and suggested my drivers were being updated. Next thing I got message to restore my Itouch to factory settings. I did this and all the problems I had with my previou Itouch's started again.
When I now plug my Itouch into my laptop it says "USB device not recognized" and the Itouch will not switch on. I've done everything including reinstalling Itunes, holding down the power and home key but to no avail. Looks like I'm going to have to send my Itouch back again. I have a suspicion that a Microsoft download is corrupting the drivers. If anyone can help I would be very grateful. I really like my Itouch but the fact it keeps failing leads me to wonder if I should opt for something else.

I had success with the holding down the keys and connecting to usb and using itunes to restore firmware like they show here

"USB device not recognized." "The connection between your device and the desktop could not be established. Please check your setup and try again." Tungsten E2, Outlook 2007

Hi,
I am running XP SP 2, on a Dell Vostro 1000, Palm OS Garnet v5.4.7 on a Tungsten E2. I have worked though issues relating to synchronization, Outlook 2007, Docs to Go, etc., in the past. Thank you board members!
Once I worked thru all the initial problems, my Tungsten E2 was sync' ing beautifully to my laptop until a few days ago. There have been no changes (I know of) to the configuration, but now I receive "The connection between your device and the desktop could not be established. Please check your setup and try again." On the laptop I sometimes get "USB device not recognized." I am unclear why I get the PC message sometimes and not others.
I have tried the following: (not necc exactly in this order)
Double checked Hot Sync Mgr settings: Local USB (ver. 6.0.1)
Reset the Palm (multiple times)
Rebooted the laptop (multiple times before and after the Palm resets)
Went to Support Libraries including http://kb.palm.com/SRVS/CGI-BIN/WEBCGI.EXE/,/?St=57,E=0000000001060189973,K=9550,Sxi=3,Case=Obj(3695...)
and http://kb.palm.com/SRVS/CGI-BIN/WEBCGI.EXE?New,Kb=PalmSupportKB,ts=Palm_External2001,Case=obj(1409)
Followed the steps in "Start Here" found at http://forums.palm.com/palm/board/message?board.id=windows_hotsync&thread.id=26057
Moved Backup directory as per a post on this forum
Looked for a deleted a file called "Graffiti_ShortCuts_____________" per a post on this forum
Followed the steps in HotSync troubleshooter guide you can run through located on
http://kb.palm.com
Went into Device Manager - found it shows no yellow ! 's
Followed Device Mgr Troubleshooter - went all the way thru with no solution
Tried all four USB ports - the PC's bell-like tone does not sound when I disconnect or reconnect the Plam's cradle like it does when I conn/disconnect other USB devices -I think that is a clue. ...?
Cleaned the Palm's contacts (and cradle's contacts with a old, dry toothbrush)
Read all the posts under "USB device not recognized."
OK, I'm at a loss, can anyone help me? Many thanks in advance!

Post relates to: Tungsten E2

Hello!
Using a cradle with the Tungsten E2? Tried bypassing the cradle and just use the hotsync cable? Tried a different computer yet? Somehow, the PC is having problems getting a signal from the device. I assume you have the laptop charger plugged into the laptop during this? Not going through a docking station or port-replicator.
One crazy thing you can try is unplug the charger from your laptop, remove the battery from the laptop and leave it out for like 10mins and put it back in and reboot the laptop. This should not cause side effects but still contact your OEM to make sure that nothing else is needed after leaving the battery out for extended period of time. Keep me posted.

My new USBs are not showing up in Disk Utility

HI ! I just purchased 25 new USBs to upload biz marketing content to. The USBs are not showing up in the FInder (I've checked all the options in the Preferences Pane) nor are they showing in Disk Utility. What am I missing? Or should I just return them?

Let's clarify what you have written:
1. My usb drives seem to work with other usbs (that have been used on both mac and windows machines before - still works).
What specific USB drives are you refering to?
Are they the 25 in question?
Have you tested the USP ports on your MBP with other USB drives (not the 25) or other peripheral devices to make certain that the ports are functional?
2. I've had the usb's reformatted on a windows machine and we were able to plug it in to an old mac to see it there.
Are these the 25 USB drives in question? If so, what was the format?
3. It is only when I have returned to my office that ONLY these usbs do not work.
These are the 25 USB drives that have been formatted and are seen on the 'old mac' but do not appear on your MBP? They still do not appear in Disk Utility?
Is this a Mavericks issue? How else would it be visible on older Mac's and not my new Power PC?
It should not be a Mavericks issue
What do you mean by 'new Power PC'? Are you using a MBP or a Windows machine or is this a typo? Exactly what MBP model are you using?
Ciao.

Getting 'USB device not recognized' message when I never did before.

Hi there
I am constantly getting a USB device not recognized when I plug in my nano. I never got this before and as a result all it does is charge. It is not showing up in iTunes anymore so I cannot remove or dowload new songs on to my nano anymore. I have tried to go into control panel and the USB Hub device manager to deselect the power outage option but that did nothing. Please help! I seem to encounter trouble with any accessories Apple sell, whether they be earphones or USB cables.
Thanks

i'm getting the same problem too.
my ipod is nearly about 1 year old.
i use my ipod nano 2GB for music and as a flashdrive to store my uni work.
this morning accessing my files in the ipod on the computer was fine.
then later in the afternoon when i connected it into a computer i keep getting the msg 'usb device not recognised'. also itunes dont recognise my ipod either anymore.
i use Windows XP at home and uni.
i've tried my ipod on at least three different computers at uni and just tried at home.
same msg came up 'unknown device' from windows.
i've read the other posts in the forum and it mentioned about 5 R's and resetting it.
BUT the main problem is i DONT have any back up of my uni work and files and they are really really important so i CANT reset the ipod otherwise i will lose all the important things...my assignments, projects, photos...I was meant to make a back up b4 i start uni next monday but i guess now is TOO LATE.
I've noticed that the socket of the ipod dock conector to usb cable, that connects to the ipod is slightly split open.
Would this be causing the problem?
I am in Utter Despair and Desperation at the moment.
Can anyone help me PLEASE?
i would be sooooo grateful for your kind help and time.
kind regards,
a student who is on the verge of a breakdown due to this problem.
