Hello I want to use USB Flash drive(Memory stick)instead of Floppy Drive as media for data storage & as data carrier. I did tried to use available USB drivers for DOS as USBASPI.SYS DI1000DD.SYS to detect my USB stick So ok by using these driver my USB stick does get detected and i can carry out file transfer operation between USB stick & harddisk. But once i unplug my USB stick to copy data from another pc & again replug it to same pc then it doesn't recognise.What i have to do is that i have to reboot my pc then it detect's attached USB stick. So are there any drivers by which i can use my USB stick freely as plug and play in DOS as floppy or as we use USB stick in windows.So that i don't have to reboot my PC. Ashish S Dhane

I don't think DOS will allow hot-plugging of USB. Maybe somebody here knows better. M2 If at first you don't succeed, you're about average.

M2 is correct. Hot-swapping is usually a Windows/Mac/Linux k2.2+ exclusive... http://www.answers.com/topic/hot-swap

The secret is to unload the USB drivers and then reload them again when you plug your stick back in. Most of the usbaspi.sys drivers won't unload and of course not all of them work either. The early Panasonic works best for me. Try the batch file in USB.ZIP at: www.urlfly.com/te That's my solution...

Followup: This works for DOS 6.22 - If you're running something else, you may have to tweak it. Also, you'll probably want to "rem" out the last line. The first time I access MY drive, I get an "abort, fail, retry" message. That line saves me having to type retry. (You don't want that drive letter anyway) Mike

DUSE USB Driver can be loaded/unloaded from COMMAND LINE: http://www.pocketec.net/downloads/duse_4_9.zip

Ahhh yes, DUSE4 Wont run in protected mode and eats up 180K of conventional memory. Sooo, when you're through playing with it, you have to reboot anyway. Doesn't sound like much of an improvement.
