Now it is certain that there is code in Shuangmi's BIOS that fully supports USB usage in DOS. I have downloaded the relevant BIOS and hope to analyze its program together with interested friends and refine it. Since Shuangmi is not willing to open up this technology, we have to do it ourselves. I hope that through our efforts, all motherboards can be equipped with this function, so that DOS can play a greater role in development!!!!!

Repeating it here just hopes that the moderators can work hard for it together! : )

The analysis and tracking tools can't separate the USB part. It's a pity there's no source code. Hey, I'll try harder. If it really doesn't work, I'll have to give up eventually ^_<
