Description of the problem
Some users of Dewesoft USB instruments on Windows 11 may see a message that DEWEUSB.sys driver has been blocked because the driver does not pass the Windows driver policy:
Description of the solution
This can happen on new or recently updated Windows 11 computers because of an updated Microsoft driver policy when legacy Dewesoft USB drivers are installed.
To fix the issue please download and install the latest Dewesoft USB driver (v3.4) from our webpage. Direct link to the driver.
