How to flash rebadged ASUS CRW-5224A cdrw?

I bought an ASUS CRW5224A cdrw drive(52x24x52x). It’s firmware version is
1.20. When I tried to upgrade its firmware, the utility tells me it can’t
find the device to upgrade. I guess the reason is, the burner is
recorgonized as “CRW5224A”, instead “ASUS CRW5224A”. That is, the part
“ASUS” is missing in the name. What I can do for this situation? Thanks.
