Hi, In OTG 2.0, 6.2.3 GetStatus commands: [ A host is required to use the GetStatus command (Table 6-3), with wIndex set to the OTG status selector (Table 6-4) to request the Host request flag (Table 6-5) from the peripheral (see Section 6.3). If the B-device is not HNP capable, it shall return a STALL if it receives a GetStatus command for the OTG feature selector. ] It looks as if this is a standard USB 2.0 GetStatus() request with the wIndex set to the "OTG status selector" (0xF000). But there is a difference with the wLength, the USB 2.0 standard GetStatus() specifies wLength as 2, but the GetStatus(OTG status) specifies as 1. Is this kind of abnormal? Why it can't just use the same wLength ?
