When using that 2000-2004 Panasonic USBASPI.SYS driver under DOS with this MP3 player that uses the ATJ2075, both read and write speeds are unbelievably slow, only about 20-30K/s. QV can't even smoothly play the MP3 files on it. But when using other USB flash drives or MP3 players, the speed is normal. My motherboard is a GA-BX2000+, and the DOS I'm using is the original Win98 DOS, with only HIMEM loaded, without EMM386 or SMARTDRV. Please suggest a solution to this problem.
