Are you sure, that linux-usb follows the spec? One example: The spec
says: >>> The lower byte of the wValue field specifies the desired
configuration. This configuration value must be zero or match a con-
figuration value from a configuration descriptor. If the configuration
value is zero, the device is placed in its Address state. The upper
byte of the wValue field is reserved. <<< [USB 1.1, 9.4.7 Set Configura-
tion]
But when I submit a SET_CONFIGURATION(0) I get punished with an
error return code...
Regards,
Gregor
