The USB specification? +AD4- Or something else? This is our customer requirement. +AD4- +AD4- I have no good idea except module parameter so that we can maintain backward compatibility but be configurable out of module. +AD4- +AD4- Do you have any other better solution? +AD4- How long do you exactly need to wait? Why not figure out how long the device takes and if it fails, slowly back off until the full time delay happens and then you can abort? It's IOP issue and difficult to figure out because it depends on device itself. I know we have multiple devices with delay+AF8-use+AD0-0, but then it's recovered and detected by reset after 30s timeout, that is too long than 1 sec.
