For Gen1 isoc-in transfer, host still send out unexpected ACK after device finish the burst with a short packet, this will cause an exception on the connected device, such as, a usb 4k camera. It can be fixed by setting rxfifo depth less than 4k bytes, prefer to use 3k here, the side-effect is that may cause performance drop about 10%, including bulk transfer.
