Dear Takashi again > hw_prt_base = 0, hw_prt = 4272, appl_prt = 12187 > call elapsed // 3rd call > hw_prt_base = 0, hw_prt = 6202, appl_prt = 12288 > call elapsed // 4th call > hw_prt_base = 8192, hw_prt = 8192, appl_prt = 12288 > <<< driver stopped here... >> In above case, when 4th "elapse" is called, are appl_prt = 12288 too small ?? This time, appl_prt should be over 16384 (= 8192 * 2) ? If so, is transmission speed of my driver too fast ?
