hi,
have an ASUS ZenBook UX330UAK, none usb working, even usb-c.

If an usb keyboard or mouse is connected they are not recognized.

It can`t boot from any usb device, only with internal ssd.

On bios setup screen doesn't show any usb device connected.

There are 5 volts present in all connectors, and D+ have voltage too, but not in D-.

Diode mode readings in D+ and D- are .465

There are no protector chip, so cpu could be damaged.

Bios have been reprogrammed with a good dump, but cant reprogram kbc IT8995VG-128/DX.

What should i test now?

Thanks.

it actual for all ports? And data pins of usb 3.0?
What about camera? It connected to usb line.

Yes, all usb2 have the same value, but usb3 and usb-c lines are a bit lower. (.346)



Camera does not work either.

As all those pins goes directly to cpu, seems that cpu are damaged, I think.

System cant install/initialise driver for usb hub (maybe error of device)? Try to change CPU.

It is not a windows problem, can not boot from usb. (linux or any os)

Also sd-card it is not recognized.

Asus ezflash only "sees" ssd, so can't update bios from usb devices in bios set-up menu.

You haven't Vertyanov JIG or another EC Programmer?
What kind of ssd installed on this laptop? Can you connect it to working PC via sata/usb? Install windows on it and update bios under windows...

Hi, I could not do more test.

The owner needed it.

Thanks for your help.
