Unable to charge G2 via USB?

Plugged in my G2 overnight Saturday night when it was down to about 25%, woke up on Sunday morning to see it hovering at around 80/81% and discharging. After looking at the battery stats, I was able to tell that it charged to over 90% before stopping charging completely and starting to discharge.
I was using the original cord and power brick when it happened, if that makes any difference.
I have confirmed that the issue is not any of the specific chargers that I have around (either the cords or the brick, and have used both the OEM one as well as others) - and I have booted into Safe Mode to see if that would solve the problem - it did not.
Luckily, I was able to get a wireless Qi charger from a friend as that is the only way that my phone will (very slowly) charge.
Help!

You can install the cable driver manually by using the following steps:
1. Connect Cable to USB
2a. If PC sees cable it will ask for you to supply a driver, browse the disc and select the XP driver from drivers folder and there you go.
2b. If PC does not see the cable it may be found in the Device Manager as Other or USB Device. (device manager can be found by pressing Windows Key and Pause together) or go in through Control Panel.
3. Highlight Other or USB Device and right click and go into Properties.
4. Select Update Driver and do as 2a.
Hope this works

Help needed: blackberry keeps resetting or won't turn on after charging, especially via USB

This is a bit of an odd one and I'd appreciate any help that others can give me.
I've had my blackberry 8900 for about a year and a half now.
Whenever I charge my handset from an empty battery (e.g. this problem isn't a problem when I charge it if there's still some charge left) - either from the main power charger or via USB, I experience problems.
Whenever it's fully charged I unplug the charger and normally at this point it cuts out completely. The screen goes black and cuts out - it doesn't even go through the normal switch-off process. From then, it won't turn on for around 3 - 4 minutes (the red light occasionally appears on the top, although it's fully charged).
When it does turn on, it goes through a soft reset.
This is more of a problem when I charge it via USB but equally affects charging it from the mains as well.
Any ideas?

It's fixable. First, charge it for several hours and then WITH the
charger still connected, remove the battery a minute and replace, and
reboot.
If that does not do it, and it continues in the reboot loop
1)
Make sure you have Blackberry Desktop Manager installed.
http://na.blackberry.com/eng/services/desktop/
2)
On your PC, go to Start > Run and copy and paste the following line
exactly (meaning with the quotation marks):
"c:\program
files\common files\research in motion\apploader\loader.exe" /nojvm
3)
The Application Loader Wizard will appear -- click "Next."
4) In
the "Connection:" drop-down menu, you should see "USB-PIN: UNKNOWN".
Click the "Next" button.
5) You should then see a list of
applications ready to be installed for your Blackberry. Hit Next and
Finish and you are well on your way to getting your Blackberry back to
life. Just don't disconnect anything and let the lengthy process finish
completely.
NOTE: If you do not see a list of applications
mentioned in step 5 and instead see the message "The Blackberry Desktop
Software does not have Blackberry Device Software for the device that
you have connected to the computer. Contact your wireless service
provider or system administrator," then you must download Blackberry's
Operating System for your carrier and device.
http://www.blackberryfaq.com/index.php/BlackBerry_Operating_System_Downloads
Just
select the appropriate carrier and network type, select your Blackberry
model from the list and download the latest version. Install this
download and follow the above steps again and you should be on the right
path.

How to charge Z1 via USB to PC?

How to charge Z1 via USB to PC?
Thanks people

Its got to do with the charging power. The original charger for the Z1 outputs 1.5Amps, most lower end car chargers barely output 0.5Amps which is the lowest power rating for USB charging. The ports on yours computer give out 0.5Amps that's why it takes for ever to charge a Z1 through a computer. Even though they all out out the same 5 Volts, the Ampere is different. Try to find a car charger that gives out 1.5Amps and you will be fine

Unable to charge Microphoto with USB AA Battery Char

Hi All, Prior to purhcasing the microphoto, I went down to creative HQ store with my USB AA Portable Charger to test if my portable charger can charge the Microphoto.
The staff were very helpful and let me test on unit, and also inform me that as long as I see a "lighting" icon on the top right corner, the microphoto is charging.
After buying the microphoto, i find that I am unable to charge my microphoto with my AA charger.
The "Lighting" icon is there but the battery indicator just does not increase.
Kindly advise.
My AA USB Charger looks like this

Charging iPhone via USB vs. FireWire

My iPhone charges fine when plugged into my computer via USB cable. However, it doesn't seem to charge when plugged in using the iPhone-to-Firewire cable. Is there a reason for this or do I have a faulty cable? Thanks for any help.

The iPhone has different power requirements for changing that Firewire does not use.

Charge & Sync via USB?

Anyone had any success charging AND syncing the phone via the same USB connection? I find it ridiculous that the USB adapter covers the pins required to power the phone yet doesn't seem to charge the phone at all...
The desktop "charging" station seems to have the same problem.
I have the phone plugged into a Powered USB Hub (ie. hub is plugged into wall so should have plenty of power to pass onto devices) if that makes any difference.

I have the sony ericsson s710a. I bough the dcu-11. However, I was also unsuccessfull to charge and sync via this USB.
I remember seeing a sony ericcsson connected via USB at one of the apple stores. I don't know if it charges but I syn the phone via USB. At that time I was interested in this whole thing so I didn't pay to much attention, so I don't remember how that phone was setup.
If anyone knows how to do this, please help. Thank you.

IPod touch AND iPod classic not detected by Windows 7 or iTunes, but both are charging fine via USB.

I already tried uninstalling and reinstalling all the Apple software on my computer but that didn't help whatsoever. Both devices are fully charged, and I have tried different cables and USB ports, but to no avail. When I check for the driver software in my Device Manager (in various categories, but most importantly, the Universal Serial Bus controllers), it doesn't appear, so I figure that might be the basis of the problem. Is there somewhere that I can download the driver since it's not automatically installing when I plug in the iPods?

Do the USB ports work for for other devices?

Charging iPod via USB hub???

Hi Folks,
Does anyone know, if it's possible to charge the iPod battery by using only an USB hub (with external power), while computer is turned off?
I tried, but with my hub it didn't work. Has anyone experienced the same?
Thanks

The hub does not send power out until the computer tell it to.

Charging iPod via USB

I have my video iPod and its USB adapter for charging it on a computer. My computer with all my music on it is getting repaired. If I hook up my iPod to another computer it gives me the red circle with a line through it and says "Do Not Disconnect." I've already quickly clicked Safely Remove Hardare and unplugged.
Can I charge my iPod on a computer w/o iTunes and keep my old music?
What about with a computer WITH iTunes... Can I stop it from dumping my music and uploading the music on that computer?

Yes, you can charge it on a computer that doesn't have iTunes.
If the computer does have iTunes, you may see this message when you first connect it.
Click 'no' or 'cancel', then safely eject the iPod, leave it connected and the iPod will charge.

Charging phone via USB removes custom ring/notification tones.

Per phone instructions I put my custom ringtones on my SD card. Now when I connect my phone to my laptop for charging during the day POOF, all the ringtone/notification tone customizations disappear and the custom tones disappear from all the menus.
An added "feature" of this situation is that toning is altered from the expected.
How does one stop this behavior?

when you plug it in, pull down the notification
press on usb, and set to cahrge only
if you mount the sd for the comp to see your phone wont have access to it

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.

The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) 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%.

Charging iPad One vs iPad 3rd gen via USB...

just got an iPad 3rd gen. As I've read here, apparently, the PC's USB port doesn't supply enough power to make the 3rd gen battery charging icon say "charging". Instead, it reads "not charging". However, it initially DOES say 'charging', before changing to 'not charging' a couple of minutes later.
Question: my iPad 1st gen ALWAYS charges via PC USB port. Why? Both AC chargers are 10 watts I believe, so why would the 1st gen charge while the third gen doesn't? Does the 3rd gen require more charging watts than the 1st gen unit does?

Using the 10W charger, an iPad 1 will charge in about 3-4 hours, however, the iPad 3 requires about double the time. How long does it take to charge your iPad 1 using the PC's USB port?
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) 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).
