SRX300 – Signed Driver for USB Console Port

All been a bit quiet here for a while, so just posting a small note to keep the blog flowing.

Normally I connect up to hardware via a USB to Serial Cable. The SRX300, a newer model of the small/medium sized branch Firewall/Router comes with an USB interface. This differs from the USB input port you get for updating firmware. The box ships with a standard USB type A to USB Mini Type B cable (link just for identification purposes) and  I thought i’d test out the on board USB port and supplied cable.

When I connected it up to the laptop, device manager identifies it as Juniper Networks BX Series System Console. When I searched around the web and Juniper website I couldn’t seem to find a driver that would work.

Eventually, I found a site which had a bit of information regarding the on board connection, a SiLabs USB->RS232 interface. And reference that Juniper has used a modified version of the chipset driver. In the link below there is a driver that has been signed by the author and instantly the driver worked for me. So worth a look, that being said, you can’t beat your good old USB-Serial console port but handy if you ever forget it on the road!
