ISA problem!!!

Takes a lot of time and solved a lot of problems I passed the compiling for Hellow sample at last.
After that I made an ISA driver by DS2.5 with source 280-28f
and load it successfully
but when I test it it always report error:
    when read    it report \"0 byte read\"
    when write   it report \"0 byte written\"
ask for help..........

你的这些描述信息在哪里看到的？你没用DRIVERMONITOR看一下，驱动执行的过程吗？
