Is there 12 volts on the front USB?

Question

motherboards

I have 12 volts, more precisely 11.2, coming to the front USBs, what could be the problem? Has the power supply gone wrong somewhere? Let me explain, I assembled a computer from rubbish, my mother was intel dx58s0, i-7 percent, I inserted a flash drive into the front USB, it didn’t work, although it worked, ... I scored, the next day I put the phone in for charging, I also safely rested in another world, then it dawned on me to measure the volts, and showed 11.2

Answer 1

What USB version?
If USB 3.0 and older - then there may be 12V and 20V
