Power speakers with USB port

Before I buy a pair of USB speakers, could I power them using the USB port on the airport express then run the 3.5mm cable to them for the music?
I'm sure this is a daft question, but I thought I'd check.

That is correct, although the Express will power a pair of headphones nicely.
The audio port on the Express is dual purpose as it will work for both analog and optical digital signals.

Is it safe to use the Belkin power strip with USB ports to charge my iPad? Or is the iPad USB adapter the safest route to take when traveling with device?

Is it safe to use the Belkin power strip with USB ports to charge my iPad?
Or is it better to travel with the Wall Charger provided with iPad?
Concerned about safety of the device. Thanks for your thoughts.

The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

Z87-G65 power issue with usb(port reset failed)

All,
I'm having an issue with my motherboard and wanted to see if anyone had suggestions. In windows 8.1 if I have my webcam or external hard drive plugged in USB. I get this error the the USB device is not recognized and the port reset failed(code 43). I noticed when I turn on the PC and it's booting the light on the webcam and hard drive flash like it's not drawing enough power to stay on. The boot sticks at 9c on the screen and I have to reset. When windows boots they turn off. Since it's before windows boots I think this is either a MB issue or a power supply issue. I have a corsair 750 watt power supply so plenty of power. Any ideas?

Print not response when i connect T1100 Epson to router RT-N16 ASUS with USB port???

For my macbook pro that I brought July 2010. I can print with T1100 Epson printer connect directly to my mac but when I connect T1100 to ASUS Router RT-N16 with USB port and I assign print to T1100 pass through wireless It's not response. How do we do please ???
Many Thanks for your answer...

Hello Shawnondrums,
Welcome to the HP Forums.
I see that you are having an issue with the printer shutting down when attempting to connect to the wireless network.
A very important step that gets easily over looked is, please make sure that you have the printer power cable connected directly to a wall outlet and not a power bar/strip. Here is a document that uses a LaserJet printer as an example but it is meant for HP products in general. Please click on the following link that explains the Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector.
Once the printer is back on, please use the on/off button to do a proper shut down and restart. This will also do a semi power reset on the printer.
If the troubleshooting does not help resolve your issue, I would then suggest calling HP's Technical Support to see about further options for you. If you are calling within North America, the number is 1-800-474-6836 and for all other regions, click here: click here.
Thanks for your time.

You should be syncing your contacts with an app on your computer or cloud service (iCloud, Gmail, Yahoo, etc), and not relying on a backup. If you haven't been doing this, start now and then restore your old backup. You will then be able to sync the new contacts back into the phone. However, you will lose all messages, etc newer thant the backup.

My iphone5 wont charge with usb port but works fine with wall plug... Infact computer. Doesn't recognizes the iphone

Battery not charging with usb port but works fine with wall plug.. So the prob is computer is not detecting the iphone5 . This problem started after upgrading to 6.1.3 version

Try to see what happens on another computer. If it works on another computer, the issue is not at the iPhone.

Mac Book Pro Power Adapter with USB charge ports?

Does anyone make a MBP power adapter with 2 USB charge ports? It seems logical to have one power adapter that charge your MBP, iPhone and iPad all at the same time while minimizing the things one would have to carry on travel.

Hopefully!
I said to them "you dont even need to put the ports on the brick itself, put it on that little wall plug adapter thingy... that way if you only want to charge your iOS devices you can leave the brick in the bag!... Fingers crossed and thanks again for the help tjk!
Best,
David

Anyone having issues with USB port power after upgrading to iTunes 11.1?

After upgrading to itunes 11.1, I can no longer use the USB ports on my wired keyboard to synch my iPhone 4s, ipod Nano, and Ipad 2. Previously, I could use this port to synch and charge the nano and iphone, and synch (but not charge) my iPad. Now I simply get an error when I attach any of the devices ("a usb device needs more power").
I currently use all four of the USB ports on the back of my imac (UPS power supply, aformentioned keyboard, a Lacie backup drive that has its own power supply, and a superdrive). Interestingly, when I unplug the Superdrive (which is plugged directly into the mac on a separate USB port), the USB port on the keyboard will work. Unplugging any of the other 2 devices does not allow the port on the to work.
I bought the wired keyboard to have the easily accessible UBS port to synch my nano as well as the fact I needed a number pad.

Get yourself a good self-powered 7 port USB hub to plug your extra devices into.

Brand new ipod nano will work when attached by cable either to a power adaptor or usb port but stops immediately when disconnected, despite being put on charge with different adaptors. Battery indicator remains constantly on lightning flas symbol and whit

My Brand New ipod nano (sold to me two days ago by Apple as replacement for previous ipod nano -15 months old and therefore out of warranty - which had suddenly stopped functioning altogether) will operate only when attached by cable to either power adapter, usb port on my laptop or when playing on a docking station. When detached, it stops playing and screen goes dark and it will not respond to any buttons, despite being charged several times for many hours on different chargers. The battery indicator stays on lightning flash symbol on white background and has only momentarily shown fully charged symbol once !
I am baffled as to why this new ipod has a similar problem to the old ipod.
Is there a virus out there which can have this effect and which I may have picked up on my Pc and have inadvertently transferred to both ipods when sync-ing ?
My PC has Norton anti-virus software.
Any suggestions , please ?

Sounds like the Nano has a faulty battery. You should be able to have Apple swap it out again for you at no cost.

Syncing music with USB port 1.1

I just got an iPod classic 160GB, but it doesn't communicate with my computer properly.
I tried to put some songs to the new iPod, but after syncing 20 songs I got the error message "Attempting to copy to the disk "(iPod name)" failed. The disk could not be read from or written to."
I called AppleCare to solve the problem, and the guy told me that I need to upgrade the USB port from 1.1 to 2.0.
Does anybody know if I really need to upgrade my USB port to 2.0?
I read some of the topics on this discussion page and some people were saying that the USB 1.1 works with iPod classics.
I also want to know if any of the transfer cables which convert FireWire to USB2.0 works with iPods.
I don't want to spend any more money to upgrade my computer to make it work with my iPod.
(I had to upgrade OS)
Please help me to get my iPod work!!

The USB port on your Cinema is a port on the built-in hub in the display. It can't supply the power needed by the iPhone.

Video issues with USB port replicator with Digital Video

I have a T400 running Windows XP SP3 32-bit, with the graphics mode set to use the ATI video card. I'm also using the latest approved Lenovo ATI driver for this machine.
I have two issues, one of which I consider major:
1) Sometimes when I plug in the replicator (got the latest drivers off of the Lenovo download site) everything works great, and other times the monitor never powers up. I plug the replicator into my laptop and the external keyboard and mouse work and the port replicator system tray icon appears, but the monitor is still in power-saving mode. If I try to activate the monitor by "extending" or "mirroring" it, it comes up with a pop-up that says:
"ThinkPad USB port rep. device: Error" - "Fail when adding device instance into driver!"
2) This is more of an annoyance, but I noticed when the monitor does work that black areas of the screen end up getting sparkly green lines through them. They aren't "actually there" in the sense that it's not corruption from the computer, they are simply artifacts of what seems to be some signalling problem.
Any help is greatly appreciated.

Your reply is 2 months later, I had to revert to Office 2010 and return the laptop to the end user.
But, I got another model of the same laptop right now which can be used to test it, I will let you know if it works out this time with the lates DisplayLink software for Windows.
