refractor list_find_previous_item & list_remove_qhd to act on ehci_link_t* instead of ehci_qhd_t* fully support 1ms, 2ms, 4ms, 8ms for period list (each list has a dummy queue head) - change period list structure limit the maximum polling interval to 256 ms add max_loop static MAX number of iteration for list_find_previous_item add test for close 256ms polling interrupt
