After update, USB is not working, can't do a hardware test. what now???

I did the software update.
After that my 1 and only USB port is not working anymore.
Totaly dead.
Cant do any hardware test, since they ask to use a dvd. Well no USB so no Disk Drive So no hardware test.
Also the online test is not working.
Need to download a file. which is failing to.
Dont know what to do.
Please help

I'd try a SMC reset first.

I need these Devices because they are my only network access via the Asix USB to Ethernet Adapter.
After the installation I have compiled and used the drives for the Asis adapter.
The both other devices are my USB Keyboard and Mouse.
2. My other problem is, that after the update my resulution of my console is very weak, this is just bad but not a real problem, I can live with that.
Thanks in advance for helping me

After updating software ipad not working

I can log in but no apps are working after updating to IOS 5

Generally a sign that the iPhone had previously been jailbroken or
hacked to work with other than the original wireless provider and the
update has relocked the iPhone to the original carrier. You must
now contact that original carrier to see if they offer unlocking and if
you qualify.
Terms of Service for this forum prohibit discussion of jailbroken iPhones.
Google may provide some direction. Contact the developers of the
jailbreak - they support their software, don't they?

After upgrade USB Keyboard not working to unlock cryptdev-ed HDD

Hi,
Is there any sane reason, why my USB keyboard does not work after upgrading right now to enter the keyphrase to unlock my hdd? (x86_64, kernel 2.6.28-1.1, luks encrypted hdd that contains an lvm2 volume) The keyboard works fine in grub, short time before I have to enter the password, it goes black (numblock LED turns off). Luckily I have an USB-to-PS/2 converter, so I just plugged it in there, the system recognizes this and I'm able to enter the password. Afterwards, pluggin the keyboard back into its USB port, it works again.
Has anyone encountered the same strange behaviour? Or has anyone a solution for this problem?
best regards

Even worse, my LUKS key is stored on a USB-Stick. After upgrading, my USB-Stick was not recognized and so the LUKS key could not be read. Luckily (very luckily) I had defined a plain text keyphrase for LUKS slot 2 and so I was able to enter this via the PS2 keyboard. Anyone who has not provided this "backdoor" for themselves faces a difficult task.
A bug report exists concerning this problem: http://bugs.archlinux.org/task/12867

TS4079 Since the latest IOS update Siri is not working correctly on my IPhone 4S. What happened?

Any help in understanding why Siri is not working properly would be most appreciated. Siri has not been working properly since I received the update to iOS 6.0. Siri acts as though it is looking for an answer or making an appointment for several minutes , but never answers the questions, makes the appointment, or Siri give nonsense answers. As of this moment, Siri is of no use to me at all.

Try these steps in order
-Restart iPad
-Hard reset(Hold power and home button until it restarts)
-Backup and restore
After the restore, set it up as new iPad. That way we can tell if it is the software or a hardware issue.

After my last OSX update: usb ports not working on my apple numeric keyboard

I'm curious if anyone else has lost usb connectivity on a Apple numeric keyboard after the last OS X update. I get the error msg "USB device needs power, connect usb disk (jump drive) to power or a usb port on this Mac". I am using OS X 10.9.1 (13B42) and the last update I took was iMovie 10.0.2 on Jan 25, 2014 on an 27' iMac (late 2012) i7 3.4 GHz, 3TB fusion, 32Gb RAM, GeForce GTX 680MX 2048MB video. All four usb ports are be used and are active on the back of the iMac. All I need is the occasional acess to a couple of jump drives via the keyboard ports. I have just ordered a 3.0 powered usb hub (Satechi) This will soon be a non-issue, but I know it used to work and I'm thinking that the OS X update might has done something to my keyboard ports. Anything?

The keyboard ports are usually slower transfer rate than other ports, so would likely be unsuited for use with flash or USB storage. There is usually an upper limit to the system load of all the ports together, perhaps that load is near the maximum already, too.
Hopefully the powered USB hub will resolve the issue.
Good luck & happy computing!

SA30 USB do not work after reinstall, please help!!

Hi, my SA30's USB do not work at all after reintalling, I do not have the original CD with the laptop as it is a gift from my mate.... I couldnt find the driver from the website, please could anyone help me???
I could use the USB mouse but when I plug the external hard disk in, it has no responses, I tried to search for new hardware, it couldnt detect it. Any information would be appreciate, cheers.

When you instll another OS than the recovery OEM OS you have to install the drivers and tools in a right order!
This order is on the Tools & Utilities CD in a html file! When you follow these order all hardware should be detect!
Also you can go to http://eu.computers.toshiba-europe.com and download the drivers

I got that message with all of my libraries. Do see if the galleries are still on your iDisk mount your iDisk and go to the iDisk/Web/Sites folder and look for a folder titled "_gallery". Inside of it should be folders for each of your galleries. The folders are titled with 6 digit numbers which makes it difficult to know which folder is for which gallery.
Thanks. "_gallery" is empty
Have you tried re-syncing as Larry suggested?
I'm sure it will work, but I'm perplexed as to how this could happen.
Do you find that iPhoto now launches faster? Perhaps it's because my web galleries are gone?

After doing a widows update itunes will not work at all

after doing a widows update itunes will not work at all

hiya!
I get the itunes has encounterd a problem and needs to close, sorry for the inconvenience error, no specific error number. I do not have QT installed,
not having QT installed is what will be causing your itunes error message at the moment. let's try a careful standalone QT 7.1 install.
download and save a copy of the QT 7.1 standalone installer to your hard drive. (we'll run the install from there rather than online.) switch off antivirus and antispyware applications prior to the install.
Quicktime 7.1 Standalone Installer
if that install goes through okay, does your itunes launch properly again?
(if you get an error message on the QT standalone reinstall, let us know what it says. include error message numbers if you're getting any.)
love, b

The wish list only works on apps you have to pay for. To get it tap the icon of the app you want to save. After it opens at the upper right corner is a box with a arrow. Tap that then tap add to wish list list in the box that opens.

Sometimes you have to reset the SMC two or three times for it to work, don't know why. I've seen that error message before and 100% of the time it was fixed with an SMC reset. I suppose it's possible that your keyboard or mouse IS drawing too much power, do you have access to another you could try?
