Descriptors programmed into an I
String Descriptor Indexes
An index of 0x00 indicates the string is absent. If the string descriptor is present, the index value is the
beginning address location divided by 2. String descriptors must not cross I
boundaries, i.e., the starting address must be moved to the next I
Pipes
The ISD-300A1 provides four USB pipes: Default Control, Bulk Out, Bulk In, and Interrupt.
Default Control Pipe
The default pipe is used to transport standard, class and vendor-specific USB requests to the ISD-300A1.
