While these instructions are specifically for USB devices that use FTDI Chip components, it's likely that similar options would be present on other USB to Serial adapters that are also experiencing communication problems. The following procedure will show you how to reduce the USB transfer sizes and latency timing. Performing a firmware recovery or firmware update may fail unless the driver settings are modified. Digi RF radios operate at lower baud rates than are optimal for these drivers and can cause some communication problems when performing certain tasks. The default configuration for FTDI's drivers are optimized for high speed serial devices. Digi interface boards and USB adapters use an FTDI Chip for the USB to serial conversion.
