Q. Just got my daughter a new samsung galaxy ace mobile and she is trying to transfer music from her laptop to her phone but when we connect the phone to the laptop with the USB cable it doesn't recognise the device, we didn't get a disc with the phone and im unsure if there is something we can download from the samsung site or elsewhere that would allow us to connect both together to allow her to transfer her music to her phone, thank you in advance :-)

How can I connect a HP Laserjet 1012 with no wireless printing support to samsung galaxy note 10.1?
Q. How can i print using HP 1012 laserjet printer using usb cable connection. I have OTG cable for samsung galaxy note 10.1. What software will be needed to connect and print through HP 1012 printer?
the printer is without wireless support, and i want to print in complete absence of any windows or mac PC.
A. Then you'll need to buy a Lantronics print server.
What Micro USB cable that provide fast charging?
Q. Hi,
I bought PowerGen 3.1A Wall Charger, when I use with original Micro USB cable that come with my Samsung Galaxy S4, the charging current is 1.9A, when I use with a generic USB cable, the charging current is only 700mA. (I have a way to test the charging current)
Does anyone know which Micro USB cable that carry fast current, such as 1.9A like original USB Cable that come with S4, or even better, carry up to 3.1A that this Wall charger provides?
Thanks All.
A. One - it is not a "charger", it is simply a power supply. The battery charge control circuit is inside the phone.
Two - re. the 3.1A, you can't do that. The power supply acts like a (nearly) constant-voltage supply and the phone presents an effective series resistance, resulting in current E/R. The only way to force more current into the phone would be to increase the voltage output from the supply. This would likely burn up something in the phone - maybe the battery.
Think about it: Some of the outlets in your house are likely 20 amp outlets, wired with 12 gauge wire. Others are 15 amps, wired with 14 gauge (smaller) wire. Will a 100 watt light bulb draw more current, hence more power, hence give more light, on a 20 amp outlet vs. a 15 amp? Of course not. The outlet supplies 110 to 120 volts, the bulb has an effective resistance when running up a little more than 100 ohms, resulting in a little less than an amp of current and so a power usage of 100 watts. It doesn't matter how much current the outlet can supply, as long as it's at least as much a the load requires.
Regarding your 700 mA problem - that would have to be one very poor piece of USB cable to limit current in that way. Let's do the numbers...
Assuming the Samsung cable had 0 ohms resistance, then if the phone is pulling 1.9A at 5 volts, it has an effective resistance of just 2.6 ohms.
5 volts at 0.7 A would require a total R of 7.14... call it 7 ohms. So the generic cable would have to be adding 4.4 ohms to the path. Or 2.2 ohms per side (2.2 on the +5 side and 2.2 on the ground side).
Even if it's #30 wire, it would have to be 22 feet long to add 4.4 ohms to the path! (#30 is about 0.1 ohm/foot)
But, you could just try looking for the fattest Micro USB cable you can find and see what happens.
Keep in mind that current to a phone is not only charging current.. the phone uses different amounts of current at different times, depending on screen on or off, network conditions, etc... and even battery charging current varies a LOT over time. I wonder if the real issue here isn't simply a change in conditions between measurements.
