Hi, i want to communicate with usb device using bios command.I know that bios support hid class and mass storage class, but does it support other usb classes (and is it full support )?is it possible to communicate with usb device by sending to usb port bytes, treating classes as unneeded element. how it is during pc initialization (before system starts) is usb device classified (hid, cdc, msd...) or is it treated as a device with byte exchange without class abstraction layer? thanks in advance
