AN1886 - APPLICATION NOTE
More Information.
The overall lengths of the
DATA0
and
DATA1
packets between each function on a
multiple-function device are equal. The data field of these packets is the longest length supported by the
functions. For example, with a multifunction device that supports data retrieval from a piece of test-and-
measurement equipment and keyboard input, the test-and-measurement function requires a 512-byte
buffer, but the keyboard requires only 16 bytes of data. The following examples show the resulting DATA
packets that may appear: Incoming keyboard data from the USB keyboard function.
[SYNC]
[DATA (16 bytes of keyboard data) (496 bytes zero-filled) ]
[EOP]
Incoming test-and-measurement data from the USB test-and-measurement function.
[SYNC]
[DATA (512 bytes test/measurement data) ]
[EOP]
NOTE: To see the problem, a USB analyzer is required.
This fix is recommended when you are using multiple-function USB devices. This fix does not affect single-
purpose USB devices. For additional information about Windows 98 and Windows 98 Second Edition hot-
fixes, go to the Microsoft Knowledge Base, and request article 206071,
