USB 1.1 Device Does Not Appear In Image for DOS
Please note: This article applies to version 1 product(s) only.
Problem:
Your USB 1.1 device does not appear in Image for DOS.
Cause:
USB 1.1 support is not enabled in the Image for DOS environment, or is not supported by your system.
Solution:
Enable UHCI support in Image for DOS using the UHCI environment variable. To enable the UHCI environment variable, you can either set it manually, or within a batch file. The command required is as follows:
set IFD=UHCI
If you are using other Image for DOS environment variables, such as IBXT or CDWS, you will need to separate the variables with a semicolon. For example:
set IFD=IBXT;CDWS:4;UHCI
If you wish to set Image for DOS environment variables in AUTOEXEC.BAT, you must use a DOS floppy diskette. A floppy diskette created with MakeDisk will not use AUTOEXEC.BAT. (However, you can use MakeDisk to enable UHCI support; please see below.)
