Hi,
I use a modified version of Keil's USB CDC-ACM function class implementation. It works really well but I am having a problem in the way I am using it. I use the virtual COM-port to connect as a modem to the host PC. My target connects through PPP to the USB CDC-ACM input/output. This allows me to create multiple sockets for multi-channel TCP/IP communication. This creates the problem! With increasing communication throughput my application showes signs of instability. I am looking for a way how I could limit the data throughput at the USB device level. Could someone provide me with an feasable example of how to achieve this? I appreciate your help - thank you!
