Help! I have quite a few USB devices, a USB keyboard and a USB flash drive. Normally under DOS I use the motherboard's built-in driver for the USB keyboard. There is no problem using it. But after I load the USB flash drive driver under DOS, my USB keyboard gets locked up! The USB flash drive can be used, but the keyboard can't! No way! My config is like this: device=himem.sys /testmem:off device=USBASPI1.SYS device=Di1000dd.SYS files=10 buffers=10 dos=high,umb stacks=9,256 lastdrive=z I personally think maybe reloading the USB keyboard driver in config might solve the problem! But I still can't find a DOS USB keyboard driver. So now I'm asking the moderators for help!

Try using some parameters when loading USBASPI.SYS. Or load the OHCI/UHCI driver for the USB keyboard as well.

Is it USBASPI1.SYS or USBASPI.SYS? Mine can't drive the USB flash drive! --- ----- ---------

You can try both USBASPI1.SYS and USBASPI2.SYS, and use whichever one works better on your system.

I can use USBASPI1.SYS, but USBASPI2.SYS doesn't work! As for the USB keyboard, it just won't work! After loading USBASPI1.SYS the keyboard is the same as if it wasn't installed As long as the keyboard isn't USB, it works fine!

Then can loading OHCI/UHCI drive the USB keyboard?

No! I feel like control of the USB has already been taken over!

It works! It's just that you can't use the USB flash drive when it's plugged into the USB keyboard's hub!
