Table 5 – Device Descriptor
Device Qualifier Descriptor
The device qualifier descriptor describes information about a high-speed capable device that
would change if the device were operating at the other speed. For the ISD-300A1, none of the
descriptor information requires modification, thus only one Device Qualifier Descriptor is
required. The ISD-300A1 returns the same descriptor while operating in either full speed or high
speed mode.

Table 6 – Device Qualifier Descriptor
Standard Configuration Descriptor
The ISD-300A1 requires two configuration descriptors. The first configuration is returned when
the VBUS_POWERED signal is active, the second configuration when the VBUS_POWERED
signal is inactive (brick powered). The configuration descriptor contains information about the
ISD-300A1 device configuration. Each configuration has one interface that supports four
endpoints. See the
VBUS_POWERED
section on page 38 for more information.
