I’ve been evaluating the new Juniper SRX300 range of Firewalls, specifically the SRX300 and the SRX340.

In addition to the usual RJ45 serial console port, these devices also feature a mini-USB console port, which is basically just a SiLabs USB->RS232 interface. Unfortunately, Juniper decided to use a custom USB VID:PID coding in the firmware, so the standard SiLabs driver won’t work.

To make matters worse, Juniper didn’t sign their custom driver that they provide. The result is that you can’t install their driver in a Windows OS that requires driver signing (such as Windows 10) without compromising your client OS by disabling that requirement.

My solution was to purchase a code signing certificate and sign the driver myself. Since this was at some personal cost to myself, I’m making it available for others in a similar situation, so they don’t have to purchase their own certificate. I did this after contacting Juniper and not receiving a prompt response.
