Loss of power to onboard USB and PS2 ports

Hi jhunix,

I'm going to need even more information; The devices that use PS2 connections, which device is it, and how many of those devices do you have?

One thing that might be a problem, if the issue you see is intermittent, I would check the PS2 connector and see if the pins are bent or broken. PS2 connector pins sometimes will bend or break and this can cause some connection issues if not completely stop the keyboard/mouse from working... Also given the age of your PC the PS2 port may just be bad, but this is not a fatal injury to a computer.

Replacing the Keyboard and Mouse with a standard USB keyboard and mouse, should resolve all of your issues.

PS2 is an older technology that keyboards and mice used to run on; Now however USB connections are used.

Further more, if this an HP Desktop with 2 USB ports on the front, and 4 USB ports on the back, you will want to avoid using the 2 USB ports on the front, especially on older HP and Dell Desktops, the reason is the power supplies often do not have enough power to run multiple USB devices on the front USB ports.

The back ports should be fine regardless of the number of devices.

Hope this helps.

Short answer, no. The ribbon supplies power to the motherboard, the disk drive and the usb ports, as well as the controller port. Without it, nothing will work.

The pinout is as follows when looking into the cable like this;

Pin Name Description
1 DATA Data

Dualshock and Dualshock 2 uses this for powering vibro-motors. Voltage on PS2 is 7.6V, however many sites says it's 9V. But it will work on 9V too.
4 GND Ground
5 VCC Vcc
6 ATT ATT select
7 CLK Clock
8 N/C Not connected
9 ACK Acknowledge

You might think about a USB hub for all your USB devices. ps2 port is more or less dedicated for mouse, which is why your mouse pointer is stuck in the middle of the screen. Go ahead and get an externally powered USB Hub to power other USB devices. To answer, ps2 for mouse needs just a mouse, not USB device.

Because there are so many different case and motherboard combinations sometimes it can be difficult following the instructions for connecting the front panel, USB header and audio header.

Below is a few generic guide that should stop some of the confusion with the labels on the wires.

***Please note this is a generic wiring guide and we can not guarantee it will work with every motherboard. Please check your motherboard manual first. Wiring the headers wrong can cause damage to the motherboard and case, this damage is not covered by the warranty***

another handy USB wiring guide can be found here http://www.directron.com/installusb.html

this maybe easier to follow

Believe it or not, if you have a floppy drive in your computer, try unplugging it and disconnecting the data ribbon. Many times, damaged floppy drives can short out motherboard functions and even prevent computers from powering up. If that doesn't fix it, then get a usb keyboard and mouse set (wireless would be fine) or borrow some, and see if they work. If they do, then the power outage damaged the PS2 ports.

Open the case,You can find the cables just attached to the backside of Port on case.Normally they are indicated by vcc,gnd,+,-
Now check if your motherboard had got USB1 ,USB2 written on it .Your pin no 1 is the one which is mark by small square/ small trangle indication / Numeric 1 ,Now you have to attach VCC to pin 1 , Port- on pin2 , Port + on pin3 ,and Gnd on pin4

Yes, you can buy a PS2 Multitap Adapter. I had the same issue and just picked a mulittap adapter up on eBay for $8.50

i think the capacitor near by the USB port is burned out so there is no power storage or power supply for the USB ports so just have a check with the capacitors near by the USB ports if you are good at recognizing that problem ..
otherwise just contact the motherboard technician ....
he will have a check and if the capacitor is burned out he will replace it ....

any doubts reply me
i am always here to assist you
thank you

Hi sambi,

If you are currently, working on PS2 mouse port which is the error occurred as stated in your problem. Try to used other PS2 mouse which working on the other pc maybe there was a short circuit on your old mouse. If the problem persist, You can use the alternative way by using USB port to plug your optical mouse.

Try to look for ps2 to usb port converter in the computer stores maybe you can still used your old mouse.

Hope this will be helpful to you.


Best Regards,
