USB System error interrupt

I am encountering an SEI interrupt in he USBSTS. Does anyone know what is (normally) the cause of this error interrupt? I have searched through the reference manual but there is hardly any explanation to the causes of this interrupt.


I am using the iMX1064 to stream HD video from a UVC camera with isoc. transfers. The application can run for several minutes without problems but suddenly I encounter the SEI interrupt and the streaming stop.


Any help appreciated.
