Question Overloaded USB hub - now what?

[FeuerFrei]

I went and plugged a car jump-starter battery into my computer's USB port to recharge.
BUUUT instead the pc's complaining that I overloaded the USB port.
And threatens to disable the port entirely unless I unplug the listed usb devices and hit "Reset." Uh oh.

{ SEE ATTACHMENT }
Same alert for two items - a card reader, and keyboard. Hit "Reset" on one alert and the alert for the other device pops up. Alternates. Endless circle, as long as I hit reset.

Already disconnected the USB keyboard and hit "Reset." But I still get the alert highlighting the keyboard on the usb device list, advising to unplug it.

Card reader is integrated into front panel of the Dell pc, so I'd have to open the case and look for a cable to unplug.



Question is: do I have to unplug those highlighted devices right now, or can I just shutdown the pc .... and let them be disabled .... to reenable later ... somehow. BIOS?


Hoping to avoid permanent damage. Keyboard's working (typed this) ... not sure it ever failed.

Most likely the recharge current draw exceeds the USB circuit's capability. Car battery recharge involves serious amps.

Yes 🙁

I agree with the speaker above. To get it, apparently there is not enough power consumed by the computer. So you can split the motherboard. Better not to risk it. Find out the necessary power for the charge and charge with the help of the USB connector which is about 220W.

it doesnt go on your computer.
The reason they use USB for battery charging is its convenient and almost universal.
You are supposed to use a standalone charger for that monster.

Didn't take me long to realize I should have used a wall adapter. The minimal instructions for the battery kit have no guidelines for recharging. It does list key electrical specs though.

Will the PC's USB hub be ok?
I haven't restarted the PC since the day of the incident - it's not my pc.

USB ports are required to have overcurrent protection, so it should be ok. Then again, USB devices are required to negotiate for higher current but often don't, as you experienced, so it depends on how much the manufacturer cared about the specs.

Thanks for the input, Mr.!

Reviewed specs. Looks like a max 2A draw for charging. There's the problem.

Spec for battery

Charge Input: 5 V - 2 A

Anker wall adapter shorty linked to should work.
