Possible to change voltage for your USBs?

[marc512]

Iv made a previous topic about my webcam. one of the suggestions was the webcam isnt getting enough voltage..
I read that USB2.0 can deliver 4.75 or 5.25. Im just wondering my USB ports could be just giving 4.75 and my cam needs atleast 5 or something

Is there anyway i can check this out? If there is away to up the voltage please say. I know myself it probly wont work but its worth a try.

Webcam seems to work on my old pc.

Iv tried all my usb ports. Even the motherboard ones. Im beginning to wonder if its just ****** lol. Ill probly buy another cheapy thing of ebay from hongkong

(yes i know theres atleast 3 things wrong with that.)

The best way would be to use a digital multimeter, and read the voltage from the pins on the USB port.

Upping the voltage is harder however, you'll need to break out the soldering iron I imagine...

I got a small USB port thing with my msi motherboard, i couldnt get a reading of it so i cut the wire and took it directly from there.
All 3 ports on my motherboard got 4.92. I dont know about the ones on the I/O area. I was told to do this in another topic because none of my usbs where working and i was worried incase it was faulty motherboard. Turns out it was bios problem. Updated bios sorted that. I tried reading the amps at the time but i got nothing.
