Hi,
   We are using the MAX3421 USB-HOST/PERIPHERAL Controller interfaced with
the M32C87 controller through SPI for the Mass Storage device operation. We
are facing some problem with that. We are putting the M32C Controller into
Sleep (STOP mode) mode and not the MAX3421, if the USB host is not sending
any data to the controller (USB is disconnected) for 20 secs and once if we
connect the USB cable into the PC the Controller has to wake-up and has to
detect the USB drive on the Explorer. But the controller is not able to
detect, but the other things (waking up, SPI comm, UART etc.,) of the
controller are working fine once it has waken-up. Have any body worked on
this MAX3421/M32C87. Do we need to do any more things for the M32C or
MAX3421 side after waking-up. Plz revet back.

Thanks,
