CardBus USB 2.0 Enabler supports USB 2.0 and USB 1.1 hard disks and CD-ROM / DVD ROMs natively and normally doesn't require any third party driver. However, if you want support other type of USB devices or if you have compatibility concerns, you may combine USBENAB with Cypress Semiconductor Corporation (or other) drivers in any combination.
CardBus USB 2.0 Enabler is compatible with Cypress DUSE 4.x driver for DOS. However both drivers should be properly configured. Please notice, that mis-configured DUSE driver may hang on startup. In our experience, the best result is obtained when DUSE driver is configured to exact resources configuration of CardBus USB 2.0 Enabler.
Let's take an example of bootable floppy below. We are willing configure Adaptec AUA-1420 card with DUSE driver. The Adaptec card consists of two USB 1.1 OHCI adapters and one USB 2.0 EHCI adapter. On our test platform we are using memory at 0xD4000. In such case CardBus USB 2.0 Enabler will use memory as follow:
We are starting USBENAB as follow:
USBENAB.EXE /M:0xD4000 /I
In this case we need configure DUSE 4.4 driver as follow:
DUSE.EXE nou ohcn=2 ehcn=1 INT13 EBAR=0xD700 OBAR=0xD500
The DUSE 4.9 Driver however will require slightly different configuration:
DUSE.EXE ver=2 nou ohcn=2 ehcn=1 INT13
As result you should see on the screen that DUSE output of used resources exactly match CardBus USB 2.0 Enabler.
