Hi everybody! I'm implementing USB1.1 embedded host controller firmware. I have some results in communication with one kind of usb devise... But I need somebody more experienced in USB to give me some tips ... Now I'm trying to implement enumeration process for more than one device... Well - I don't know how many devices I'll have at the beginning on the bus, wich is the right way to allocate memory for the new devices detected - with functions such calloc and malloc or with linked lists? I'll be happy if somebody answer to me.. my mail is: kont40@abv.bg , my icq: 105135362
