If so, could a current NBLA device be upgraded with a new PL2303 chip of the versions PL2303 HXD, SA, RA GC, GS, GT, GL, GE, GD, GR which are windows 11 compatible? Will NIP Embedded place other PL2303 chips in the new NBLA devices to overcome this problem of automatic driver updates by windows and compatibility with it? Since last week, I still need to reinstall often the NBLA software or the PL2303 driver to have working communication with the NBLA, as more and more computers will run windows 11 in the short future, If you have problem, you can always restart the process from STEP 1.I tried to find that on the internet but nothing usefull unless you block ALL driver updates but in that case your computer is not getting the updates for other programs as well what is ofcourse not OK and not the intention. PL2303 GL works with this 5.2.1.0 driver in Windows 11. Driver version 3.8.40 does not work, you need to update the driver to an older version. When trying to connect to IS02, the Profile Editor software will show the USB driver version on the Communication Error screen. This driver version 3.8.40 does not work with IS02 in Windows 11. This driver version 3.6.81 works with IS02 in Windows 11. Windows will revert the driver back to the non-working version when any of such USB ports is used. Don’t use those USB ports that have never been updated with the old drivers.Or plug in multiple IS02 devices into all the USB ports to be used with IS02, and update the USB drivers for all those ports.Always use one dedicated USB port on the PC for IS02 devices.To avoid updating the driver again, try to stick with the following guidelines: The driver needs to be updated again in such cases.

However, when the IS02 device is plugged into another USB port, the default driver is installed again, and even the default driver is used again on the previous USB port.

The updated driver will survive the sleep and restart of the Windows on the same USB port. (make sure the battery is installed for IS02.) Go back to Profile Editor, the software shall be able to communicate with the IS02. If it is a version of 2021, it is still the wrong one. It should be the version of the year 2015, not 2021. You can double click this Prolific USB-To-Serial Comm Port and select Driver to see the version. After the driver is updated, the Device manager will change the display of the PL2303 device to the following.Browsing through the following steps to pick the old driver 3.6.81. If you see only one version of driver without the version number/date, select it and complete.Right click on the PL2303/Prolific device and select Update Driver.In Device Manager, find the Ports(COM & LPT), and select the item related to PL2303 device or Prolific device.Right click on the Windows icon on the task bar and select Device Manager.
