IN: input for the USB host; OUT: output from the USB host.
Hub endpoints are not indexed.
Generic endpoint can be used as bulk or interrupt endpoint.
Port 2 can be disabled by connecting both D
+
and D
to V
CC
.
The port number is reduced by 1 when downstream port 2 is disabled.
7.2 Hub endpoint 0 (control)
All USB devices and functions must implement a default control endpoint (ID = 0).
This endpoint is used by the host to configure the device and to perform generic USB
status and control access.
The ISP1130 hub supports the following USB descriptor information through its
control endpoint 0, which can handle transfers of 64 bytes maximum:
Device descriptor
Configuration descriptor
Interface descriptor
Endpoint descriptor
Hub descriptor
String descriptor.
7.3 Hub endpoint 1 (interrupt)
Endpoint 1 is used by the ISP1130 hub to provide port status change information to
the host. This endpoint can be accessed only after the hub has been configured by
the host (by sending the Set Configuration command).
Endpoint 1 is an interrupt endpoint: the host polls it once every 255 ms by sending an
IN token. If the hub has detected no change in the port status it returns a NAK (Not
AcKnowledge) response to this request, otherwise it sends the Status Change byte
(see
Table 4
).

a logic 1 indicates a status change on downstream port 1
Port 2 SC
a logic 1 indicates a status change on downstream port 2 or on
embedded function 1 (downstream port 2 disabled)
Port 3 SC
a logic 1 indicates a status change on embedded function 1 or on
embedded function 2 (downstream port 2 disabled)
