I have seen software broken because USB drivers can mess this up. However your using the other classes which I have not used and I believe take this sort issue into account. I have a project that one day will want this sort of USB connection. Good Luck... I may come asking questions when I finally get there myself... | |

We need to transfer sensor information from discovery board to the java program running in linux pc which itself is another similir board. And we need to send engine commands from java side to the discovery board. Right now I need to transfer 250Bytes every few mili seconds but this will be increased in future. | |
