USB lost after 10.4.5 update

This only appears to be a problem on my G4 Powerbook, which I updated yesterday to 10.4.5. Today when I plugged in my SD card reader nothing happened. Then I unplugged my wireless USB Kensington mouse and tried that port and nothing happened. Then when I plugged my USB wireless mouse adaptor back in, nothing happened. So now it appears to I have no connectivity through either USB port, at least with a card reader or USB mouse, both of which are bus-powered. Any thoughts?

After updating Mac OS system, I noticed USB camera connection and card readers were not recognized, I tried several card readers and nothing happens. Do you have any suggestion or idea? I really think it is something related to the upgrade, maybe something Apple should fix in the Mac OS upgrade after 10.4.5 and 10.4.6 because before that it worked perfectly.

No USB power on wake up to PCIe USB card after 10.6.8 update. how to fix?

Ever since 10.6.8 update my PCIe USB card does not provide power to USB devices after Mac wakes from sleep. I have to restart to get it to work. How do I fix this before I down grade back to 10.6.7?

I did a clean install on a brand new hard drive and found that both Remote Desktop Client 3.5.1 and OX 10.6.8 caused the PCI express to not provide power to USB devices. I have firewire but nothing plugged in to test. I updated each one separatly (under separate install test) and both had the same effect. The only way to fix I have found is to not install either one. I have send Apple a feedback and rang Apple Care to let them know. I don't know when a fix will come through. I am in the process of doing a fresh install of all my software to 10.6.7 (without R.T.C. I might get Lion but I will only install as a V.M. under Paralells 7 which I can use as a test bench from now on.

Keyboard not recognized in USB hub after 10.6.3 update

After updating to 10.6.3 (using combo updater) the keys on my Apple extended keyboard that shipped with my 24" iMac (2008) no longer work when the keyboard is connected through my Belkin powered USB hub. But oddly enough, the wireless mouse that is connected to the keyboard does work. So the keyboard is recognized and connected properly, but the keys don't work! It's definitely a software thing.
I don't have enough free USB ports on the back of my iMac to dedicate to my keyboard. Any help appreciated. Thanks!

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 quits after 10.4.11 update and can't read external Lacie drive contents

Performed update through Software Updater. (After reading this forum, I now know better for future updates) Now, my USB ports don't work and external Lacie drive looks blank. Plugged USB devices into PC and they work fine. From PC on same network, I can see all the files on the Lacie. Repaired disk permissions, shut down and unplugged everything, even power cord, and let it "think" for several hours. Still same problems. USB lights up for a few seconds then shuts down. Tried all USB ports, same problem. I can connect to external HD but it appears that all the files are gone.

Still not working.
I ran applejack, then re-installed the combo upgrade for 10.4.11, gave it several restarts, still no USB power or access to external HD. One thing that I notice, when starting up and the grey screen is up, the USB is lit. As soon as the little clock thing starts "running" in a circle, the lights go out. If I unplug then re-plug the USB devices, the lights come on for just a few seconds and then go out. Same results with and without USB hub in both ports. This is our old machine used mostly by kids for iTunes so we must attach the iPod to it or they will be on the new iMac, fresh out of the box!
BTW, we were 'tricked' into this upgrade. iTunes gave an error message saying that we had to upgrade or some features would no longer work. After the upgrade, iTunes said it would not load until we upgraded the OS X. I just jumped from 10.4.3 to 10.4.11 because that was the latest version. I have always trusted Apple and never had a problem, until now

Unable to hear sound via usb headsets after 10.10.2 update. Any advice? Thanks!

We just updated our school iMac lab to 10.10.2 and now several machines will not play the volume through headsets while on System Preferences. We have plugged/unplugged and made sure that usb is selected within system preferences. Sometimes, when we go into an app or website that USES sound, it will then work! Unfortunately we have high-stakes testing happening over the next couple of weeks and we need to be able to test the sound prior to taking the test.
Any ideas? Any help would be greatly appreciated! Thanks!
Sharon

sorry, lost track of this thread for a bit.
you need to figure out which preference files in the main account are causing the problem. the one that i suspected is not it. I don't know which one it is, sorry.
maybe somebody else does.
one thing you can always try is the nuclear approach. move the whole folder /users/username/library/preferences to the desktop and log out/in. that folder will be recreated and all the files inside will be recreated with default values when system needs them. see if that fixes the issue. if it does you can start moving the files you need from the preferences folder on the desktop back to the one in the library. you'd need to log out/in for some of them. this is pretty time consuming so I would first see if someone else has another idea.
in the worst case scenario you can always migrate to a new user account.

USB problems after Windows 8.1 update

Since I updated to windows 8.1 my USB ports have problems. The issues occur when I am trying to use a USB to serial cable. It will work for a short period of time and then stop. The error I get says connected device quit responding. Then it will start working again. Sometimes the system will crash and the error is that the driver unloaded before a que'd request was finished. When this happens, it takes about 5 minutes for the computer to come back up.
I had no such issues before the upgrade. Cisco anyconnect, VPN software no longer works either and I don't have the software myself as it was emotely downloaded by my company tech support, but any suggestion for fixing it would be appreciated as well.

The following document..
Release Notes for Cisco AnyConnect Secure Mobility Client, Release 3.1
..contains this statement.
Note: When upgrading to Windows 8.1, uninstall AnyConnect, and reinstall it after your Windows upgrade is complete.
For help with this situation, post in the Cisco forums.

Trouble accessing files on external USB drive after 10.6.8 update

Upgraded to Mac 10.6.8 on my MacBook Pro (I'm not a techie, but the "About This Mac" thingy says 2.53 GHz Intel Core 2 Duo, 4 GB 1067 MHz DDR3 - I assume that means something to somebody). Since the upgrade, I've been having problems accessing data on an external HD connected via USB - there were no issues before the upgrade, but now it's impossible to even navigate to a particular file or subfolder half the time, as the process freezes 95% of the time (every so often I am able to get through, for no obvious reason) - usually I just get what looks like an empty folder and a little spinning thing in the bottom right-hand corner. Sometimes when I do get to a file - say it's a ZIP file - I'll try to unZIP it and the process will hang; if I try to drag it to the desktop and unZIP it there, I can't get it to copy to the desktop, I just get the "copying files" box and a bar that never shows any progress, it just hangs at zero bytes out of whatever it might be.
Also having intermittent issues with another external USB drive, which is the one I use for Time Machine - about one in every five backup attempts is successful, the rest of the time I get a message saying the backup couldn't be performed.
I have two external FireWire drives as well, and I'm having no trouble with either of those - so I'm assuming the problem is USB-related (and 10.6.8 related, since none of this was happening before the upgrade).
So - I'm wondering if anybody else is having the same issues, and f there's a solution that a non-techie like me could handle that won't make blood come out of my ears.
Cheers!

Thanks baltwo - the PRAM tip was helpful. For some reason I still have trouble accessing a few files, I'm putting that down to them being somehow corrupted. Eric, thanks, but I tried using Disk Utility and the communication problems I was having with the drive meant that the repair couldn't be performed. I may try again now that that side of things seems to be running a little more smoothly. Anyway, thank you both!

Paid for apps lost after 2.0.2 update!

I updated to 2.0.2 last night and found that all my paid-for apps have now disappeared from my phone as well as from iTunes!
How can I get them back? I had at least 12-15 and don't want to pay for them twice!

Here's the official how-to:
*How to redownload purchased applications from the App Store*
http://support.apple.com/kb/HT2519
Alternatively,
Call AppleCare iPhone...wait time can be 10-20 minutes so be sure you have time. Usually less than 10 minutes during the morning though.
Once you get to them, tell them the issue or ask directly for "iTunes Music Store Billing Support". If it shows up in your Purchase History (in iTunes click Store > View My Account then find the Purchase History button) they can set it up for re-downloading. From there, they'll direct you to click "Check for Purchases". They should instantly start downloading again, free of charge. Works for music and movies if you can prove you bought them.
Or visit www.apple.com/support/itunes/store/browser and type away. They email back in about 2 days.
Hope this helps someone.

User lost after 10.4.11 update in a macbook.

I've updated from 10.4.10 to 10.4.11 in my macbook intel. Process finished ok.
I have 2 admin users. The user from where I made the update is not usable. When I try to login with that user it shows a plan blue screen with the mouse pointer. The other user is working fine.
I've tried with Safe Mode, but when I click on the bad user, the screen bounces to the login box. There's no way to enter to that users. Which is a big problem. Of course I have tried with Combo Update, Disk Utility, etc, etc.
Any clues on this strange behavior?

Can't explain the behavior, except to say, stuff happens. Log into the good account, delete the bad one, saving data (disk image put into /Users/Deleted Users, create a new admin account using the same username/password combo, log into it, mount the saved data image, and transfer stuff from the image to the account.

Aperture 3: GPS data gets lost after 'Update from Master'

My library contains photos in JPEG format that I geotag in Places, then I save the metadata with 'Write IPTC Metadata to Master'. The problem I have is, that the GPS data gets lost after I do an 'Update from Master', even if I saved the metadata before. I'm having this problem with referenced and managed photos and all my JPEGs from several different cameras. The only way to permanently store the GPS info into my photos seems to be to export the geotagged photos as versions.
Does anybody has the same problem or knows how to solve this?
Thanks in advance,
Michael

Use Houdah geo (http://www.houdah.com) to write location data back to the EXIF. It's interface is very similar to Places (Google maps and pins) and you can interface with the Aperture library. It's a bit of a pain, but if you need it done now rather than wait for an Aperture 3 fix, then...

Many logins & passwords were lost after last update

Automatic login and passwords were lost after the last firefox update. Or should I say would not work until I re-entered them.
A search found they were still there, plus the new entries I saved.
Other logins were lost totally, no passwords were lost.
I did send an immediate report to tech support but heard nothing.
Is it safe to update the new version or am I having to re-enter my logins and passwords again.
I have used firefox for many years as my main browser, I mostly only want to use a different browser when I want to open two different email accounts.

Won't boot after 10.5.2 update (external HDD)

it boots fine with 10.5 from my external USB HDD
after 10.5.2 update, it hangs at the apple logo grey screen with gear spinning
PS: boot from external USB HDD

I have had the same problem and have so far (despite the autofsd suggestion) had no success fixing it. This is on a completely clean installation (which booted fine) with the latest updates including 10.5.2 (which doesn't boot at all).
I have installed Mac OS X on external (USB and Firewire) drives before without any problem and I wanted a development environment for some work I am doing on Aperture 2 (so I need 10.5.2) without running the risk of messing with my existing installation of Aperture 1.5.
The drive itself is the very drive the machine came with so that shouldn't be an issue, although it is of course, now in an external (powered) enclosure.
Playing with the autofsd plist (and also renaming /usr/libexec/autofsd) has had no effect.
I'll try the ps suggestion and see what that turns up.

Ipod connected to DVDR (USB) failure after completes update

Before updating my ipod, connected my ipod with my dvdr by the port usb, and after updating my ipod I cannot. Is possible to install the version previous to my ipod?

After searching for an answer i could only come with one conclusion. Maybe someone else will find another but this is mine.
1. First Uninstall the newest version of Itunes and uninstall the current version of IPOD UPDater if you have it. Then restart your computer.
2. After your restart find software to BACKUP IPOD or Back it up yourself. I used COPYPOD but you can also back up ipod by,
Other Way to BACK UP. Skip this step if you dont know what you are doing!!! (For windows users also for ADVANCED USERS YOU COULD NOT BACK UP AND BE STUCK WITH LOST FILES....) Go to MY Computer, Then the Ipod Drive. Click Tools>Folder Options; then click View tab. by Hidden Files and Folder click "Show Hidden files and folders." after that go back to the drives and start backing up my dragging files to desktop. You files will be In IPOD_CONTROL
It will be a sequences of F_10 and so copy all folders to a backup folder
IF you have files on your ipod backup files also such as .zip, avi, exe, txt, doc, etc.
3. After this you will install the updater from your ORIGINAL CD that came with your ipod. After the install restart your computer.
4. Go to the IPOD UPDATER and RESTORE your ipod. Let process complete.
5. After your IPOD RESTORES move all files back to IPOD by going to Itunes that came with ORIGINAL CD and dragging files from backup location to the device.
(YOu may have to install newer version if so, DO NOT UPDATE THE IPOD!)
6. Restart Your IPOD by Pressing Menu and the Clicker.
7. Stay tuned for more fixes that APPLE may come out with for Itunes and IPOD updater.
I took these steps and it fixed my problem but i still don't know what the cause was. i looked throught all the ipod hidden files and pref. and with no luck could'nt find it. Someone im still looking for answer as to why!
This may also work for people with AUDIO or VIDEO problems after update.

I have a question regarding my txt/alert tones. I recently updated my iPhone 5's software without first backing it up on iCloud or my computer (oops). After my phone finished updating, i lost the new ringtones and txt/alert tones i had bought.

I have a question regarding my txt/alert tones. I recently updated my iPhone 5's software without first backing it up on iCloud or my computer (oops). After my phone finished updating, i lost the new ringtones and txt/alert tones i had bought. I connected my iPhone to my computer and sync'd it hoping that it could download my purchases from the itunes store and then put them back on to my phone but no such luck. When i look at my iphone on my computer and look at tones, they do not show up at all. However, if i click on the "On This iPhone" tab and click on "Tones" the deleted ringtones and altert tones show up...they are just grey'd out and have a dotted circle to the left of them. I also tried to go to the iTunes store on my phone and redownload them and it tells me that i have already purchased this ringtone and asks me if i want to buy it again. I press Cancel. I know when i do that with music it would usually let me redownload the song without buying it again but it wont let me with the ringtones...so how do i get them back? any help would be greatly appreicated

Greetings,
I've never seen this issue, and I handle many iPads, of all versions. WiFi issues are generally local to the WiFi router - they are not all of the same quality, range, immunity to interference, etc. You have distance, building construction, and the biggie - interference.
At home, I use Apple routers, and have no issues with any of my WiFi enabled devices, computers, mobile devices, etc - even the lowly PeeCees. I have locations where I have Juniper Networks, as well as Aruba, and a few Netgears - all of them work as they should.
The cheaper routers, Linksys, D-Link, Seimens home units, and many other no name devices have caused issues of various kinds, and even connectivity.
I have no idea what Starbucks uses, but I always have a good connection, and I go there nearly every morning and get some work done, as well as play.
You could try changing channels, 2.4 to 5 Gigs, changing locations of the router. I have had to do all of these at one time or another over the many years that I have been a Network Engineer.
Good Luck - Cheers,
M.

I lost the ability to use wifi after the 8.02 update. Is there a way to fix this? I've already tried resetting network. Turned the phone off and on. Nothing is working and now I have to run on just data.

csdwarf,
So sorry to hear about the trouble with Wi-Fi! Let's get that working the way it should. Could you provide us some more details regarding where this breakdown occurs? Are you having trouble with turning Wi-Fi on or connecting to your Wi-Fi? Are other devices connecting to your Wi-Fi without issue?
