Inconsistence response of usbpipedemo, Why?

[jorgeuriarte]

Hi There,

I have placed a break in the right place on my target board and I can see the OUTpacket value received from the host, and I also see going back to the host, where I have the usbpipedemo sample running. It all looks good initially, in fact, every time I initialize the program (delphi2010) it all works great when I send a first text through the open pipes. then I get the text displayed in the input data window. If I send a second text, it goes to my target and out to the host, but the host no longer responds. It is like the byte is stuck somewhere in the netherworld.

Any help will be greatly appreciated,
Jorge
