The resistance of the usb port?

There is a suspicion of closed contacts in the ports of the laptop. Namely a shorted d+ and d - contacts. What resistance must be d+ d-? Checked the power contacts, increasing resistance(capacitor charge) is normal. Check date contacts 19 Com does not read any pendrive or mouse...

What you this information will give? Resistance there is certainly nonlinear. All you can check is to avoid breakage, or circuit.
Open and no short circuit, but neither the work nor the stick nor the mouse, etc. - athena9 commented on July 9th 19 at 14:02
to fail can not only output circuits. Though of course they often fail, but still. - Nathan_Gaylord commented on July 9th 19 at 14:05
