    Thanks for your reply。
    Yes，the HID has it's speed limitation，but I don't wan't to write a windows driver which is too difficult for me。I'v also checked the cdc class and found nothing,it is dedicated to serial 232 and NIC though the bulk transfer can be used.
    Since it is just a hobby project,the speed is not the main thing taken into account.
