    Hello, yesterday I did some tests on the fpga,using the chipscope, to understand what was really happening. I discovered that the FX2 controller during the connection with a usb port of the PC always sends a signal on the progb line causing the clearing…

    Hello Manfred, nice to ear from you again. I'm fine, thanks. I hope you too. I was hoping that doing a reset of the pipes could solve the problem, but it seems useless. Your suggestion, to save the state in RAM, is good so I try to implement it. But if…

    Hello Claudio, long time not seen! I hope you are well. I'm afraid a disorderly break of the communication between FPGA and FX-2 leads to the fact that the statemachine in the FPGA and the slave-FIFO configuration must be set up again. They are then no…

    Hello, we need to implement an automatic recovery of the USB communication in our systems using the USB3FPGA boards. I have implemented all the procedures to deinit and Init again the ceUSBAPI class and to reload the ceusb driver, but it seems that it is…
