Is there a way to connect my Cell Phone to my Tablet via USB so that I can access the data on the phone through the tablet (ie photos, music, videos)? Also is there a way to also charge the phone via the USB while its connected to the tablet (while the tablet is charging)?
No to your usb questions what you can do though is get softwaredata cable and use it to create "virtual cable"/connection between the devices

I have a custom USB peripheral that I use to communicate through USB OTG of the tablet. The device is wired in such a way, that I don't use a Y-cable. In the USB line, I have wired it so that the device can either be powered by the tablet, or it can be powered by an external power supply.
Scenario A:
---------------
When the USB peripheral device is self-powered, it directs power to itself and sends the power to the tablet as well. The tablet is charging while hosting the peripheral device. The USB connection is still intact.
When the power is pulled, the USB peripheral device shuts off completely. What should happen is when the power is pulled, the tablet should detect this and start supplying power to the USB peripheral. This doesn't happen for some reason, until the tablet is rebooted. When the tablet reboots, it detects that there is a USB device plugged in, and starts supplying power.
Scenario B:
--------------
When the USB peripheral is bus-powered, (meaning the tablet is currently supplying power to peripheral device and is currently hosting it), plugging in the power to the peripheral SHOULD start charging the tablet. This doesn't happen. Instead, the tablet continues to discharge.
So basically, I would like the tablet to supply power to the USB device when it detects that the power is gone. Alternatively, when the tablet detects power coming into its port, it should start charging.
Because I custom made the USB peripheral device, I am able to manually force the host to re-enumerate the device by pulling down the 1.5K pullup (hopefully you know which one I am talking about). Do you think this will work? In my application, I wouldn't have access to the OTG adapter and therefore I wouldn't be able to pull it out from the tablet. [That's what he said...]
How would I come to realize in my app that the power is lost and I need to re-initialize a new handle for the USB stream? Suppose I am able to do this, re-initializing the USB port will enable the tablet to start charging again?
Thanks.
I want to upload pictures from my S3 to laptop.
There is no problem with my cable and laptop because my phone was able to charge when I connect my phone with the laptop. However, my laptop didn't detect any device when I connect my phone in with the cable. Hence, I am unable to upload images / add songs to my Samsung Galaxy S3.
I need to enable fast charge/AC on USB and keep it enable to communicate via USB. I need my tablet to charge as connected to AC and be able to transfer files in the same way as if I connect to a PC.
I will have a AC adapter in the middle powering the device 5V/2A, so I wont burn my PC USB port (I wont drain any power from the PC, just the D+/D-/GND Lines...). I know that I should not connect the tablet directly to a PC once I do this.
I have my device rooted, but I do not want to use a custom kernel. Is there anything I can change on my kernel to do this?
Once I think I saw some change that I must do in a system file to be able to do this, but I'm unable to find it now...
Thanks for any tip,

How do I connect my Android TV stick to my laptop? It has no reset or power on button. Just a microsd slot and two USB ports: a regular one and a mini usb one.
Hi can you tell us a little more about your device what make brand ect ect also some photos would really help
yes model number would help a lot.
usually it is going to be connected via the regular USB connector to the PC. Then you should see the internal and/or external SD cards as part of your computers resources.
Power on and off is by plugging in the power source, which sounds like it is micro-usb. Then remove to power off.
additional tips...
Some additional tips; I hope they can help...
In the OS settings, under "Device", subheading "USB", make certain that "connect to PC" is checked.
Also, if you use a microUSB-to-USB cable to connect the dongle to your PC, make certain you use a cable that you know has all four wires internally connected.
- I was going nuts one time, trying to figure out why I could not get the stick PC to connect over USB, and it turned out I was using a cheap microUSB-to-USB cable that was intended for power ONLY. (it had only the two power wires in the cable, and not the two data wires). Swapping the cable out solved that dilemma.
Cheers!
Could some one please suggest a way in which I can avoid running down the phone's battery when accessing the internet via a hard wired connection into the USB micro port of my mobile phone?
Do you think this would work?

For this purpose I do not want to access the internet on the phone by wireless.

I have tried:
IA micro to usb adapter: Plugable: Model USB2-OTGE100. It does not have a power supply and uses my phone's battery to power the adapter.
A Micro-B usb hub that has 3 standard usb outputs and one power input. It also has a Charge to OTG switch and it does not do what I want as it does not charge the phone at the same time as browsing the internet.
