4.3.2.5.6

Set Feature

This command sets the Stall feature for all supported Endpoints. It also supports the Device Remote Wakeup feature

and Test mode.

4.3.2.5.7

Set Configuration

The device supports only one configuration. An occurrence of this command places the device into the Configured state.

Since only one configuration is supported, 01h is the only supported configuration value.

4.3.2.5.8

Set Interface

Only one interface is supported by the device. Therefore, this command is of marginal use. If the command is issued

with an alternative setting of 00h and interface setting of 00h, as shown in Table 4-32, the device responds with an ACK.

Otherwise it responds with a STALL handshake.
