Hi, I just installed Windows 8 , and tried to install the winusb driver, for the PCSGU250, which I just downloaded from the website.
This driver won’t install in Windows 8.
I get the message The third-party INF does not contain digital signature information

can you please fix this ?

kind regards,

In 64-bit version of Windows 8 you have to disable the driver signature enforcement in order to install the PCSGU250 driver.
For more details how to disable the driver signature enforcement please see:

Please use the latest driver for the PCSGU250 from this downloads page:
velleman.eu/support/download … U250&type=
Download and extract the package: “Drivers for Windows Vista and Windows 7. (Can also be used for Windows XP)”.
