W4 Windows tablet - any way to charge while also using the USB port?

I have an Acer W4 tablet with Windows 8 and I want to keep a USB printer and the USB charger attached to the tablet at the same time, but since it only has one USB port I cannot seem to make this work. I have tried an external, AC-powered USB hub which also charges attached USB devices, but it seems like the tablet won't charge when the USB port is in "host" mode, which it needs to be to talk to the printer. Anyone have a workaroud (hardware or software) for this problem? Thanks

I think the end of this thread:http://community.acer.com/t5/Windows-Tablets-and-Convertibles/how-to-charge-the-W4-820-tablet-while-data-transfer-is-going-on/m-p/271906/highlight/true#M11301has the most current info on it. Not easy but theoretically can work.

Is there any way to unlock iPhone besides using the slide?

Is there any way to unlock iPhone besides using the slide? My vision impaired Dad is slowly learning to feel his way to the approximate position of the slide and learn how to flick his thumb to unlock the iphone. Is there any other way to unlock an iPhone from sleep?

If you activate "Voiceover", your Dad can use the voiceover gestures to control the phone. These are different from normal gestures. For example, Unlock iPhone: Select the Unlock switch, then double-tap the screen.
To learn about voiceover, see this: http://www.apple.com/iphone/how-to/#accessibility.using-voiceover

What is the best way to connect my guitar to the usb port on my IMac

This is for use with Logic Pro X
what is the best way to connect my guitar to the usb port on my
I-Mac

As has been said really, the less you pay the less quality, and flexibility you'll have on your sound.
For example, you could run on a 'Rocksmith Real Tone Cable' if you just wanted a cheap way of getting your guitar into the computer for some fun. Probably cost you $30 (I live in UK so can't be sure). If you're starting out then this could be considered the best option for dipping your toe in the water without spending too much.
You won't get a really nasty sound out of that if you can process it yourself in Logic afterwards to clean up, but it won't be great either. I imagine it could get quite noisy so you'd need to get heavily gating your guitar sound, if you're playing something clean that's not ideal.
Longterm, you're far better getting a decent audio interface, as you need something to play sound back through, if you have different input sources you usually have to create an aggregrate device on osx to use multple sources at once esp if you're using the built in audio chip on your mac to listen.
All this can add latency and possibly sync issues (i.e. drum tracks not in time with audio etc.), although generally it's not too bad, but it's something worth knowing if you want to do things on the cheap without buying a dedicated interface.
What kind of money did you want to spend? Are you thinking super duper cheap, and then see how it goes and maybe spend more in future if you enjoy it? Personally i would say £100-150 would get your something good to start with, like that Presonus audiobox, there's a lot of options like that available.
My local music shop always push the alesis io2 on new users, gotta say i'm not that overly impressed with it. Line 6 stuff will be good however, but limiting. Although i beleive you get their software for free with it?

Is it safe to use the USB port in my car to charge my iPhone 5s or do I need to buy a car charger?

Is it safe to use the USB port in my car to charge my iPhone 5s or do I need to buy a car charger?

Check car manual to see if it supports charging ,some do not
or use a USB 12 volt plug in for the "cigarrette lighter" socket and plug into that ,probably a better solution

With the original ATV is there a way to use the usb port with external hard drive?

Is there a way to use the usb with ATV1 and external hard drive?

I have the same question and refuse to beleive that Apple would put the USB port there for a HD and not be able to use it for that purpose.

Is there any way to get accurate framing using the iPhone 5 camera?

The iPhone 5 has a 16:9 screen, yet the photos are still produced in a 4:3 ratio. So what you see on the screen while framing the shot with the native camera app is not the same as the photo you end up with on your camera roll.
Is there any way to fix this? I want my photos to look exactly like how they appear on the screen before I hit the shutter.

I just realized this just now cause there is always some extra frame added when I review my pics on camera roll. This site might illustrate the problem further..
http://blog.crushapps.com/2012/09/with-the-iphone-5s-camera-app-what-you-see-is- not-what-you-get/
The only solution Ive found is to use an ap Like Camera Asesome or Kitcam App they do use a 4:3 framing and take pics of exactly what you see on screen..
However, I feel this is a design flaw by apple, you should be able to take a pic exactly to what you see on screen... I dont care if there is a black bar on top or in bottom(or both) on screen, rather than having an overscan of what your actually are saving on your phone. And its completely ridicoulous cause images appear with black bars when you review them on Camera Roll where the overscan would be nice (estetically wise , and a double click would reframe to what you actually took)
Hope this answers your question..

Is there any way to get Mail to use the Inbox as the Sent folder?

This may sound like a silly question, but I have an IMAP account with over a hundred nested folders. I've tried using rules to sort email that comes in, but honestly? It's more trouble than it's worth. Generally, I leave emails in my Inbox until I've dealt with them, and then I sort them into the appropriate folder.
Unfortunately, this means that I've then got to go and do the same thing with the message that I've just sent—which I sometimes (often) forget to do. I then end up with hundreds and hundreds of messages in the Sent folder that need to be hooked up with their respective originals. Bleh.
Does anyone know if there's a way to get both the original message and the response to end up in the same folder automatically? Mail doesn't allow you to use the Inbox as anything but the Inbox—it's the root directory for the mailbox.
Anyone?
BTW, I'm posting this here because I have Tiger at work, where this is more of a problem, though I've got Leopard (and soon Snow Leopard) at home.

Go easy—I've been using Macs since 1984 and have only used Microsoft's bloatware when work obliges me to. (I talked the boss who insisted that we run all of our email and calendars from an Access server into running OS X Server; Entourage went away, and life is much better. Word is still part of my everyday grind because of change tracking, but I have hopes for Pages.) I've used any number of email clients over the years, and Mail is my app of choice for many reasons.
Nonetheless, a useful feature is a useful feature, even if it comes from Redmond. It's not 1996 any more—Macs aren't the downtrodden Rebel Alliance and Microsoft isn't the Empire.
It seems to me that—especially with an IMAP account—you're not dealing with something intrinsic in the structure of the emailing system, since the folder structure doesn't even reside on the client computer (except as a mirror).
I suppose that I could use a rule to shunt all email for that account into a single folder and then use that same folder as the Sent folder. I'd need to create the same rule on my various Macs (and punt on my iPhone)... but I suppose that would work. But I'm still not sure why a more elegant solution isn't possible.

Recently changed my email provider. However, Calendar continues to try to send alerts to my old email provider. I have not found any way to tell Calendar to use the correct email address. I have chained iCloud, AppleID, and local email settings.

Sorry for the long title - I thought I had to explain my entire problem there ...
I recently switched ISPs, so now I have a new email address. I've updated mail, can send and receive successfully, recreated my iCloud account, and made sure my Contacts entry was correct. But Calendar's alert function stubbornly tries to send email to my old email address. I haven't found any way to change the list of email addresses that Calendar uses. This is the Calendar desktop app, not iCal. Any tips would be appreciated.

So what was the solution. I have a similar problem on all of my devices now

Is there a way to turn 'passcode on immediately' while also using the fingerprint sensor?

If I turn my fingerprint sensor on in the new iPhone 5s to use as the passcode, it requires it to be used immediately after locking. I would like to change this to 1 minute but there aren't any other options when the fingerprint sensor is on. Is there a fix to this?

i am wondering the same thing. Also there should be an option where you ONLY have the fingerprint unlock instead of also having the numerical password when sliding phone.

Not normal. Take it to an Apple Store for evaluation.

The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W 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 (2.5W, 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

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.

In rare instances when using the Camera Connection Kit, you may notice that iPad does not charge after using the Camera Connection Kit. Disconnecting and reconnecting the iPad from the charger will resolve this issue.
