i use the testcap as an model, i delete it’s time function, when the
SRB_READ_DATA command arrived ,i make the 7146 works ,and then i use
StreamClassStreamNotification function with StreamRequestComplete

trouble.

From your ISR queue passive level callback via StreamClassCallAtNewPriority( … Low … ) and
complete your SRB from there.
