68013 always pending operation

Nov 12, 2008 1 Replies

When I use Cypress EZ-USB control panel to output data to 68013, the task is often pended, the softwaer shows "pending:OpIndex=38: OpType=4=Bulk Byte Transfer" Who can help me to solve the problem? thanks!


In EZ-USB control Panel's manual, it tell us when send a "IN" to 68013 but no data in the FIFO of 68013, the task will be pending. But why a OUT command will leads to pending ?
