Hi,
I am working to implement Wind River USB peripheral Stack on Synopsys USB 1.1 IP
I am using "USB Complete" as a reference for me
In "USB Complete" I found these two phrases
1st
"Disconnect
A downstream port is in the Disconnect state when a Single-Ended Zero has
lasted for at least 2.5 microseconds.
"
2nd
"Reset
When a Single-Ended Zero has lasted for 10 milliseconds, the device must be in the Reset state. A device may enter the Reset state after the Single-Ended Zero has lasted for as little as 2.5 microseconds. A full-speed device that is capable of high-speed communications performs the high-speed handshake during the Reset state.
"
I get confused is it Disconnect or Reset State after 2.5 microseconds?
Dose this means that: in case of reset state I get 1st Disconnect interrupt then I get a Reset Interrupt?
Best Regards
