I'm implementing an USB Host using PIC18F452 + SL811HS. The embedded hos can work properly now with USB Mouse, KB and some other low and full spee devices. The enumeration and data transfer processes are all OK. But the problem occurs when I interface the host with high speed devices The host can send Request Commands to device successfully, but cannot ge data back. In a multiple-packet data stage, the host can only receive th first packet and all the following packet are missed.
Anyone has suggestions ? Thanks in advance !
