Hi balbi, Currently,the RX DMA MODE1 is setup only after a packet has sit in the RX fifo. I just wonder if this way works?I was told that MODE1 should be setup before receiving the first packet,or we have to setup MODE 0 to unload the first packet and then switch to MODE1 for the remaining packets. thanks Cliff -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
