You need a special charger for the A700. There are two extra contacts to change the tab. This is due to the large battery.

I understand that I'd love to know the pin layout of the normal charger I'd try to make my own but at least it charges from my nexus 7 charger but what am trying to figger out is why it won't connect to my pc via mirco usb

I've decided to make my own charger the pin layout is pin 1 is 12volt+ and the pin 12 is 12 volt - I read that from another forum if this mod works I shall upload photos

[Q] Car charger?

Will the Desire HD car charger work for Inspire as well?

Thanks
Consider they're basically identical phones yes, it will work. Just about any micro USB charger will work.
Thanks....
I bought this because of the extra USB port.

Yes an NO lol. All depends what ROM you are using , what kernal is flashed and your device. You could "possibly" run a command via terminal but you wont have the function of both. It will be one or the other.

I would like to mount a USB memory device simultaneously while charging. Are you saying this isn't possible
Sent from my HTC One X using Tapatalk 2
I think usb otg and charging in the same time is not possible as the two use the 30 pin connector, so you need accessory that is otg and has a socket to connect for charging in the same time, i have not seen this accessory yet
All otg cables i see has a socket only for usb stick and some has additional sockets for sd cards as the 5 in 1 accessory (i have one)

External usb drive and charging

Is it possible to connect an external USB HD and still charge the tab? (Tab 2 10.1)
I am fitting it in the car so will be constantly connected to car charger but also need the HD connected and ideally 1 or 2 spare USB ports (hub)
Can this be done?
Thanks,
Mark

Yes should work with a double side usb cable
Be careful the Tab is drawing high current level by itself , you will need at least a 2amps car charger

Ok, cheers for the reply...
Hard drive will have its own power supply and I'll use official Samsung car charger for tab...

the one I have doesn't charge-- even when using a male-to-male USB cable. But it does work with OTG

Can I use a cheap otg cable, or are the expensive ones better?

Cheap cables are just fine.
Also, it's impossible for the phone to charge while using OTG. For OTG to work some of the pins are used for handling data and therefore cannot be used to charge.
I ordered one from china, took about 3 to 4 weeks, then I ordered from ebay..
they work fine... they only work with jellybean....

Actually, the thing that prevents charging isn't the pins, it is a software toggle that turns the phone's port into a power supply for the external device, the charging circuit is switched off in the pm chip. There are charging/power usb otg host cables available for phones that support it, e.g., Nexus 7, with patched CM10.1, and the phone can get charged while usb hosting.
the 4 pins are still 2 data, two power, in otg mode.
I don't know if a software fix would work for captivate. I've got the datasheet for the cappy power management chip somewhere. if I can find it, I'll report if the chip can support it and if so, then maybe the N7 fix could get ported to cappy.

AW: USB OTG Cable
I use a 0,70€ cable... I don't recommend it, the connection between phone and usbstick interrupts too often.

Yea. It's a bit of a gamble when buying cheap cables. I also bought a really cheap usb otg cable from dealextreme and the connector on the phone's end is too loose. The OTG cable that came with Nokia N8 is ok.
I use this OTG cable: www.amazon.com/Electronics-Micro-USB-OTG-Cable/dp/B005GGBYJ4/. Small US company, offers a lifetime warranty, only takes a couple days to get from Amazon (free two day shipping if you have a Prime membership). I've had a few from them and never had an issue (other than I tend to lose them). Perfect fit and just the right length. Good stuff.
AW: USB OTG Cable
I bought one from Conrad electronics here in Germany, it costs like 6 euros and works perfectly.

I bought a cheap £2.99 cable from Amazon UK which works just fine.
The packet it came in states the brand as 'Afunta' (Made in China).

[Q] Wirelss charger and usb otg

I have an odd issue whereby I cannot charge my phone with my wireless charger if data is being written to my usb otg , charging worked fine after I took out the usb otg. Any solutions? Thanks
Read somewhere on here before that someone else had the same problem with a mhl adapter. Don't think you can use anything in the port while charging wirelessly.
To my knowledge it can not be done. I know that with cyanogenmod and wired charging with a y otg cable work but not with stock rom.

Confirmed. I have a Meenova. When it's plugged into USB in usb-otg mode, my Qi charger won't work. Running Slimrom currently. Does it on both my Nexus 5 and Nexus 7 2013.
