i finnaly make the Sheevaplug working with my Communication card (USB to Serial). The communication card is used to connect other controllers. The sheevaplug now is used as a server and run my software to gether all the information from all the controllers through the communication card. However, i found ramdonly the communication between Sheevaplug and Communication card is shutdown.
I think it might be the USB buffer overflow. does anyone konw what is the reason or any suggestions?
