If the radio you are working with appears to be unresponsive even after performing the above steps, you may need to perform a recovery. The driver is now optimized for use with Digi radios. Click OK on both windows and close the Device Manager. Latency Timer (msec): Change this to 1ġ0. Find and Right-Click on the USB Serial Port (this can be named a number of things, make sure it is the correct one for your radio)ĩ. Find the Port (COM & LPT) section in the right-hand column and expand itĤ. This is represented by the public libusbtransfer structure type. The generic transfer object must be treated slightly differently depending on which type of I/O you are performing with it. Select Device Manager from the left-hand columnģ. For the asynchronous I/O, libusb implements the concept of a generic transfer entity for all types of I/O (control, bulk, interrupt, isochronous). Find My Computer (Windows XP, 2000) or Computer (Windows 7, Vista)Ģ. This guide assumes you have a Digi USB interface board (XBIB-U, XIB-U, XTIB-U) plugged into the computer and that the appropriate drivers have been installed.ī. 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.
