Is there any chance to refresh DMA channel or Bulk-In endpoint Automatically
hardware condition：cyusb3014，fpga for send data.
firmware condition：AN65974 from cypress Website linked ”http://www.cypress.com/?rID=51581“
opereation：cyusb3014 connected fpga with slavefifo,the fpga send Data Constantly，then I open the Streamer software and Streamer will get data from cyusb3014,but sometimes later ,the stream can not get data anymore .I examine the ep 0x81 state and DMA channel state,but they all normal. then i write code to reset the ep and DMA channel.
as soon as the streamer get data normal, i send the command to reset the ep and DMA channel,the stream will can not get Data immediately, same as the err talked above, and later i will can not work anymore. but if i reset the ep and DMA channel without let streamer get data,then the streamer can get data normally.
