Hi guys, I'm having some issues with the USB ports on my laptop. There are 3 USB port on my laptop, left side 1 USB 3.0 and 1 USB 2.0, right side 1 USB 2.0.

The USB port on the right side is fine no problem at all, but the left side is very hard to connect with USB devices(mouse, flash drive), I have to like adjust and plug in the USB device to a certain position only my laptop can detect the device.

There is no dust in it and I have not drop my laptop before. It only happened recently, is it a software problem or the port is broken?

If you have to wiggle the connector to make it work, it is a physical problem with the port, not software and there is probably nothing you can do but have the port replaced by a qualified tech. If not under warranty, then you will have to determine yourself if worth the cost.

If you need more ports but don't want to spend a lot of money on repairs, consider getting an inexpensive USB Hub with it own AC power supply. Having its own power supply ensures you don't put too much demand for power through the laptop's port.

As far as how this happened, those ports really are not very robust and it does not take much to cause physical damage. With a bit of bad luck, one strong yank on a connected cable from just the wrong direction could have caused it.

Does pulling too much power does damage to the port or the device won't work at all?
"In theory", if too much power is demanded through the port, it "should" just shut down the port so no damage will occur.

But if there is something wrong already (a factory defect, for example, it won't physically damage the port itself, but it could damage a component in the interface behind it.

But to that, there is very little concern about demanding too much power if you only connect a single device to any port. Ports are designed to easily support 1 device. If a power hungry device (like a big hard drive enclosure, for example) uses a lot of power, they typically come with their own external power supplies. So no worries there either.

But when you attach a hub to a port, then connect several USB devices that don't have their own power supplies to that hub, the total demands could exceed capacities. A hub with its own power supply prevents that.

We have here whole serie of ADATA, think its UV310 and they all need to be in precise position or they loosing connection. Think it is just bad contact, the port (the pins) can be slightly worn already.
And there should be no such thing as pulling too much power out of USB, it won't provide more. In my observation some power hungry devices like optical USB drives just won't spin (with no damage to USB port itself) and need to connect the second USB for additional power.

I see, I'll try and see whether I'm able to claim warranty cuz there is only 1 USB can be used right now and it is not USB 3.0, other two only can use to connect my mouse, cannot transfer files or connect any other device.

My nephew had this issue, and he literally melted 2 of his 3 ports (and the mobo connectors behind them) before realizing what was happening, so anutha lappy in the scrap heap for him, hehehe :)

If it's not under warranty, try a Bluetooth USB mouse that doesn't require the dongle. That would free up the port used by the mouse. (If its Bluetooth capable)

Right. Not all laptops support BT so in that case, it might require a dongle.

I bought one of this, may I know how it works though? Like it still connects directly to the laptop, how does it make sure that it doesn't pull too much power from the laptop?

If it's a powered hub as Bill linked, (plugs into wall with it's own plug) it won't pull any power at all it has it's own, that's purpose of using a powered hub

As much you will "play" with the connector, as higher will be the risk to damage the motherboard connection. So, I strongly advice you to go to a GOOD repair shop.

^^^This^^^.

When you use a self-powered hub, the hub provides the necessary power the connected devices. Only data is then routed through the notebook's USB connector. And the USB specs call for the USB interface to support up to 127 devices! So no worries there.
