Hello Folks, Under MS-DOS 6.22, I have been working with the Panasonic USB drivers from www.dosdays.co.uk: usbaspi.sys and di1000dd.sys
These USB drivers are a big improvement in attaching flash drives and USB hard drive external drives to a DOS machine. These drivers are limited to using USB Mass Storage only. And yes, I have been limiting disk partitions and file systems to FAT16, less than or equal to 2 GB. But the drivers are not robust. The drivers cause MS-DOS 6.22 to freeze often when using newer, faster, larger flash drives. Older, slower, small 0.5 GB and 1 GB flash drives seem to work best with these drivers. Moreover, these drivers freeze regularly if loaded into DOS high memory. A lot of division overflow. I think because new, large flash drives are so fast; I have been getting the DOS error message often: "Abort, Retry, Fail?" New, fast, large flash drives work a little better if I plug the flash drives through a hub, to help slow them down. It would be a big plus to FreeDOS, if someone could locate or even develop USB drivers that are robust, work with the newest, large, fast flash drives, and will support all general USB devices.
