    Hi Rami,

    the only case where I regularly experience "diasppearance" of USB Blaster is when other FTDI USB FT232 or FT245 instances are connected to the computer, e.g. a FTDI USB-to-serial bridge. Have you other devices connected to the said USB hub?

    As far as I'm aware of, the FTDI problem exists since many years and has never been solved. My solution is to switch to a different USB-to-serial bridge or a different FPGA adapter if both are needed in a test setup.

    Regards
    Frank
