Damaged USB controller workaround.

[Michael Albert]

The USB controller on my windows tablet (asus t303ua) was damaged, however USB-C port is still working fine, but it doesn't work from the BIOS, and hence the computer is technically dead, once the operation system fails.

When i connect an external HDD to the USB-C port and power on the computer, the HDD turns off in the welcome screen and then it ONLY powers back on in the operating system, it remains off if i go into BIOS.

My workaround, can i use an externally powered SATA? Is it that the USB controller isn't giving enough power to the HDD on its own?

In other words, if i use an externally powered HDD, would that solve my issue and make the HDD recognizable in the BIOS since it will remain ON?

(Thank you so much!)

MERGED QUESTION
Question from Michael Albert : "Fried USB ports on ASUS T303ua (Transformer 3 Pro)"

Hello, i have got my USB port fried, now it won't recognize any USB device and it suffers to let the LED on a memory reader turn to full power.

I bought a USB-C to USB 3.0 adapter to replace the fried USB port and use the charger USB-C port instead as an all-in-one, however, it looks like the motherboard connections have been affected as even the USB-C port is not able to work well with external devices. (hopefully it detects and processes data from devices, unlike the fried one, but it is slow)

The help i'm seeking:

1) How much would it cost me to fix this issue at Asus service WITHOUT a warranty? assuming i will have to get a new motherboard.

2) Instead of replacing the motherboard, it is easier if i find a way to read USB devices in BIOS using the USB-C adapter, because this is the main issue, i cannot run any live ISO anymore, even though the USB-C works in the operating system, it doesn't detect/read devices in BIOS.

Thank you so much!
