Due to the persistent shortage of chips, i had to use another equivalent USB to Serial converter in the later batches of the DVMEGA DVstick-30. The functionality, speed and quality of both chips are equivalent. The FTDI234 was used in the earlier version of the DVstick-30, i now use the CP2102.
Both chips are natively supported by all Windows versions. However, in a few cases it may be that the standard driver does not always work properly because drivers from other apps can influence the standard that comes with Windows. It is then advisable to reinstall the driver belonging to the DVstick-30 that you have.
In the attached document you can see which driver you need for your DVstick-30 and you will also find the download link.
