Build 224 of the vCOM virtual serial port driver is released.
There were two reports by two different people that vCOM build 222 would hand their system. Not BSOD, but just freeze. I have adjusted the thread priorities in build 224 out of the real-time range where they were set in build 222. I think that perodically the threads priority would be boosted above the GUI's thread priority causing a deadlock.
Important: You will need to edit the N8VBvCOM.inf file to match your current inf file before updating the driver. Once you have the inf edited you can run the update.bat file to update the driver.
