I've noticed when I have my tablet plugged into my computer via USB it doesn't appear to be charging. The battery icon is showing a red lightning bolt. This is different than when I have my tab plugged into a wall socket.
Working as intended or..?
Your PC USB port can't supply enough juice (500ma max) compare to your wall socket (>2000ma) to charge while power the tab. Turn the tab off and your will get some charge off the USB port.

It's been charging my tab for about a month now with no problems at all, but I'm not here to argue, if you feel that you know more than I do. I've charged the tablet using that adapter from my laptop, PC, and Energizer XP4001 Power Pack.

Ahh thanks! Was wondering why it wouldn't charge via my USB port.
(In fact using my Samsung Focus USB adapter for the outlet doesn't seem to work either... I need to use only the Samsung Tab USB adapter)

The focus charger is rated only about 700ma (same exact one as Captivate/SGS), marginablly better than PC USB. GT 10.1 has a rather large battery and hence it requires much larger charge current. You don't see any laptop get charged via USB, do you?

Is that through the orginal AC adapter or through PC USB?
Turning off the tablet and charging it via USB works, but it takes forever!

And you are not the only one who is waiting twice as long before his tab is fully charged. Then we can open a topic "Why does it take so long before my tab is charged?" As foxbat stated: You don't see any laptop get charged via USB, do you?
So if I say your adapter doesn't work its just as accurate as your answer it does work.

Hey, I'm not here to argue with you. I'm just an idiot.
Go about your business, and don't listen. I'm ok with that.
First of all, not all USB ports are equal.
On many modern PCs, the USB ports can deliver more than 500mA over USB if required. This is definitely true for pretty much all Macs since 2007, and quite a few mainboards from other manufacturers (see this article for some background).
Secondly, I've had one of these adaptors for quite a while now, and have used it regularly to charge my Galaxy Tab 7" which uses exactly the same power supply and cables as the GT 10.1. I can categorically state that when using this adaptor, it the GT7 does charge from a Macbook Air and a 5000mAh external battery that has a 1A output USB port labelled for an iPad.
Whilst it might not be as quick as the wall charger, it is definitely much faster than attempting to charge the GT7 from the same devices without the adaptor, even if the device is in use.
I've not formally tried to charge my GT10.1 with it yet, but I did check to see if the "not-charging" indicator went away (which it did), so I rather presume it will work much like the GT7.
Regards,
Dave

You don't need to embarrass yourself by saying you're an idiot, It's very childish and the second time you mention I'm supposed to be smarter then you. I'm sorry you take this so personally.
i just use the supplied cable and it charges via usb on my computer. it shows not charging, but it basically trickle charges when the tab is both on and off

Went to local electronic store and rigged up a mod for laptop charging, it basically charges with any usb port. Time to make a few spares .
one thing in the laptop it wont transfer data but it charges with my 1 dollar cigarette charger lol
why was this needed?
(new to tablets, waiting for an HTC tablet)
The tab doesn't charge when connected to a PC.

Interesting... Why is that?
are those resistors connected on pin 2 and 3? or better yet... got diagram?
The tab needs a power source that produces 5v @ 2 amps before it will charge properly.
Mine charges fine with my laptop...I beleive it only trickle charges, alot slower then the wall plugin, but it does charge.
wow 2 amps?
USB spec is max 5v 500mAh or 500mw? (2.5w ~) ? ... confused.
USB will charge the tab. However charge time is much longer due to lower USB power output.
When I go to Menu>Settings>About Tab> Status it says it isn't charging when it is connected to my laptop and the battery icon has the lightning bolt charging symbol but has an 'x' next to it so I assumed it was telling me the truth. BTW what clock widget is that in the OP picture?

While that is the USB spec for devices that are intended to use USB for data, occasionally you run into devices that will trickle charge off a 500mA connection but require a higher amp connection, usually provided by a specific wall wart plug, to rapid charge. The iPad had a similar function/issue if I'm not mistaken.

The galaxy tab charges just fine through usb connection on a pc or laptop, if ur doesn't u have two things to check, first are u using a usb2.0 or higher port and is your device set for usb storage file transfer, u can check in settings while connected to a pc or laptop, I charge my tab almost everyday using my pc as I transfer a lot of files daily, I don't even notice a difference in charge times compared to charging via an electrical outlet.

There's an existing thread about USB charging here: http://forum.xda-developers.com/showthread.php?t=845844
It includes schematics and other ideas regarding charging.
The charger is absolute CRAP. 3 feet long and cant be powered by usb? WTF?
Any idea how I can fix this? Longer one or a adapter or something? Id prefer to charge from my laptop/desktop
anything from bestbuy? need a fix asap
Yeah, no idea why it's so short... really annoying. you could try an extension cable?
http://www.amazon.com/Belkin-F3U134...ZWXA/ref=sr_1_1?ie=UTF8&qid=1308614970&sr=8-1
Oh, btw, you CAN charge via USB, but it's just reaaaaally slow. If you use the tab while plugged in, you might not even gain charge... just slow it down. The battery in the 10.1 requires much higher amperage than USB can provide.
Just an FYI. A regular USB 2.0 extension cable wouldn't work with the Transformer (which also has a short data cable). USB 3.0 extension cables reportedly worked though.
Hi, everybody.
i just buy a samsung galaxy tab 7.7 and just noticed only can be charged by using the power socket provided by samsung.
now i found a way to charge your tab by your laptop or PC through samsung STANDARD USB DATA CABLE cable.
First, download the software (ASUS Ai Charger) attached:
Second, just install and enjoy to charge your tablet through use cable.
FYI, battery indicator still showing no charging but actually it is charging.
you can check after one minute by viwing the remaining power up.
Thanks.
Is this software just raise yr usb port mah to certain amount?
If so, will this harm the computer?

My tab charges when plugged into my computer without that (or any similar software, only Kies and AOSP USB drivers installed). It doesn't show charging but the charge definitely goes up. Does that software actually make it charge faster? I have to say, I'm pretty dubious.
I would recommended getting the following adapter, I originally bought it for my original tab and was able to charge via the laptop with no problem. It charges as fast as the wall charger.

Thanks for the info.
Though it must be noted that you need an Asus motherboard for this, my Gigabyte provides 1A front USB ports thats where I charge the Tab7.7 I'll try if there is any difference real world difference if I plug it into one of the regular USB ports.
I accidentally found out I was able to charge from my Mac without using this special software as follow:
I bought an external battery, New Trent IMP99D (Amazon Link) and it came with a special USB extension cable (picture below) that is designed for the Tab 10.1. If I plug the GT7+ directly to the IMP99D without using the extension cable, NO charging takes place. However, if I use the extension cable, charging works.
I connect the extension cable to my MacBook Air, connect the GT7+ charging cable and the tablet and... VOILA.. it's charging! HoneyComb even reported that it is an "AC Charging" and it charge pretty fast.
So you can either
a). Buy the battery and it comes with the cable
b). Buy JUST THE CABLE, model IMP44B (manufacturer link here)

If you just want to charge via pc you can turn off your device, this way will work.

I recharge the battery using my pc all the time... just connect it with the USB cable and that's it... no software or anything like that... The tablet battery Icon does have a strange X on it but it still charges the phone (AHHuummm, Tablet) just like the electric plug thingy...
After a certain person (on XDA) forcing me to prove that charging VIA USB is possible, I suppose I should share with all of you guys as well. I have a MZ601, so it's an original XOOM (you don't say right? hahaha), a few weeks ago I brought a car charger that has multi-tip, so it means you can swap out the adapter and such. I tested it on my XOOM and it worked, so I came to the conclusion that the XOOM official charger was 5V but in reality when I was chatting to solarnz about it, he mentions it was a 12V and to my surprise it was. Anyways the point is if you can convert or buy an adapter pin to usb for the XOOM it is possible to use any source of USB power to charge the XOOM.
Here are some pictures so you get the idea:

So there, I hope you guys can find it useful and not flame me like that certain someone.
Edit:
I should also add, charging via USB is pointless and slow only for if you really need to. Unless you got an adapter that outputs 1.0A + it probably be faster than standard usb, but what's the point if you got your original charger?
Always good to have options.

very interesting post, i have a car charger but not multi pin...didnt know that it can charge through pc usb
Thats really good to hear, as the pin is fragile and i hate it. I have an old samsung tablet usb charger and to my surprise it did work.
Where can I find these adapters?
I've always been sure that plugging the xoom to a usb 5v 1A+ charger would have worked but couldnt find a bloody adapter that fits that unique pin
You can not charge xoom by usb.
Usb is not connected to the xoom battery.

That's not exactly charging via USB.... that's using a power tip adaptor to charge FROM a USB power source.

I no longer have my Xoom, but if I remember correctly, the Motorola dock for it charges via USB... the standard plug goes into the dock, but where the Xoom sits, there is only HDMI male and USB male connectors.
FWIW: My mother now has my old Xoom and she accidentally bent the pin inside the Xoom where the normal charger goes. The only thing that will work now is the dock to charge it until the port can be fixed.

That's correct. Just checked what you call the "pogo pins" on my OEM dock and they are at 12VDC. Contrary to the title of OP, I don't think it's possible to charge via USB.

Thanks for the confirmation. I had been using this cable (https://www.amazon.com/Tendak-Micro...07828&sr=1-2-spons&keywords=otg+y+cable&psc=1) for my Nexus 7 I had installed in my dash, and for some reason it just doesn't work with my HD 8. Even with the USB DAC not connected, the cable registers power, charges for about 30 seconds, then says it's not connected to power anymore. don't have this issue with the Nexus, or with any of my other power cables, but that's the only OTG angle cable I have.
I'll try the one you use, but I'll have to use a Micro USB angled extension to make it fit in the dash. Unless someone else knows of an OTG y cable with an angled plug that actually works for the HD 8?
Update: I've bought two additional otg cables from Amazon, and one will work for the usb device, but doesn't charge the tablet, the other charges the tablet, but won't work for the usb device. After testing both of these several times, they both started to have the same behavior as my other one, it shows charging for a few seconds, then stops, but continues to power the usb device. If I connect a normal power cable it will stay in "fully charged" mode forever and Automate reports power is connected. I'm starting to get really frustrated. I'm pretty sure it is actually charging, because when I left it connected like that for an hour, it never moved from 85%, but then as soon as I plugged in a normal charging cable it started "charging" at about 6% per minute, and said 100% within 3 minutes. Not even a QC 3.0 can do that. I'm so confused.
