Today I bought an ASUS Ai-Flash USB flash drive, 32M in size. Not long after bringing it back, I carried out driver testing under DOS, and the result is really a bit puzzling.
Using USBASPI1.SYS + DI1000DD.SYS in CONFIG.SYS for driving, at the beginning several times, the successful ones were in the majority. When successfully driven, I felt very good using it. Not only did the memory usage very little (USBASPI1.SYS and DI1000DD.SYS together occupied less than 20K of memory), but it was just like a hard disk, readable and writable, and supported long filenames (when using DOSLFN).
With DUSE, it didn't work. Although it showed "USB device detected", it couldn't load it and would wait for a relatively long time. USBASPI2.SYS also rarely succeeded. Only the effect after loading USBASPI1.SYS was really good. Unfortunately, later for some reason, it seemed very difficult for USBASPI1.SYS to succeed anymore, always showing messages like "Target not found" and leading to failure in driving. Now it's still under further research.
Just to add, DUSE supports PnP, which is really good. It's a pity that USBASPI.SYS doesn't support it. Also, my this computer doesn't have a standard USB interface, but only a PCI to USB card. I don't know if there will be any impact.
Anyone with experience, netizens might as well also talk about their own experiences and insights when driving USB devices under DOS!
