Question Asrock B75M-GL R2.0 but in bios and system read B75M-GL

[ToyCrane]

I just bought this motherboard form market place, when i check on website it was B75M-GL R2.0 but in bios and system it read B75M-GL
but everything work normally except usb port 2.0 in motherboard always said "Power Surge on the USB" when i try to plug usb inside windows.
is it because wrong bios that usb 2.0 not working? or the problem from the motherboard?

R2.0 with usb3 front panel and B75M-GL without usb 3.0 front panel
as u see at the first picture my motherboard is R2.0 but
when i download new bios in asrock website the motherboard can't read R2.0 bios but B75M-GL can
how i can check my usb 2.0 short or no?

i already connect my usb 3.0 front panel and it's work but in bios system browser it's show there's no usb 3.0 socket

is it possible seller force to flash B75M-GL bios to R2.0 motherboard?
