HI,
I use the following code to enable portsc of uhci
under DOS,but the port enable failed (set the bit but
it doesn`t take effect) , I don't know why . Is there
anyone know what's the problem ? Thanks :)
static void uhci_reset_port(unsigned int port)
{
unsigned short status;
I want to know how to drive usb host controller/hub to
send request to my usb device under dos , Does anyone
help me about the way to it or have example code ?
thanks in advance
