If you try many bios same not bios problem check usb port and check motherboard maybe component damage remove hdd/cdrom check switch button all other hardware.

I'm puzzled.
you ask problem hang logo or only USB not work ?
Note: When I try many BIOSes, the same problem shows that the laptop has a different hardware error.

There may be a different reason.i just say what i see.hanging when logo comes as well as usb not working.there is one chip pch with cpu and as the chip is not available,i can not change it.
