I think ISP 1582 is USB Host Controller. You mentioned the issue with USB
Client.

Have you looked into Interrupt Line from your USB Client ?



If USB Client Interrupt got stuck by some reason, ActiveSync will be
disconnected.

Can you provide more information about your issue ?

Thank you.

Dear Friends:

Thank you very much,
ISP1582 is usb2.0 device driver, not usb host, for usb
massStorage mode, it works stability, but for ActiveSynch mode, when we
copy big file, it often terminate.
I search related document from internet, other friends say they
also find this problem, but I don't know how to solve this problem.
Please help me, thank you very much.

Best Regards
Mike Han
