Host requests

The ISP1130 handles all standard USB requests from the host via control endpoint 0.

The control endpoint can handle a maximum of 64 bytes per transfer.

Remark: Please note that the USB data transmission order is Least Signiﬁcant Bit

(LSB) ﬁrst. In the following tables multi-byte variables are displayed least signiﬁcant

byte ﬁrst.

8.1 Standard requests

Table 5 shows the supported standard USB requests. Some requests are explicitly

unsupported. All other requests will be responded with a STALL packet.

Port 4 SC

a logic 1 indicates a status change on embedded function 2 or on

embedded function 3 (downstream port 2 disabled)

Port 5 SC

a logic 1 indicates a status change on embedded function 3; not used

if downstream port 2 is disabled
