I've installed Slackware 14 on an old machine and bought a wireless usb dongle, a RaLink RT5370 for the network interface. I've installed WICD 1.7.2.4, and rt5370-2.5.0.3 from SlackBuilds. However, when I run wicd-curses it says No wireless networks found.

lsusb reports:
Any thoughts?

P.S. I not excatly new to linux, but since I'm not running X my knowledge of all the commands is not up to par.

Your hardware is detected, but the rt5370 driver you built from Slackbuilds may not be loaded. Run lsmod to see all the modules loaded. If there is no rt5370 module, try loading it manually with modprobe.

I ran lsmod and found the following modules loaded:
I did some more research and found out those modules listed above have to be removed and the module rt5370sta needs to be loaded.

I now have an interface ra0 which I activated with ifconfig ra0 up

However, when I run wicd-curses still says no wireless networks found. Am I still missing something?

I fear that you have reached the limit of my expertise here. I have never done wifi via a usb connection. My laptop has a built-iin pci device. All I can tell you is that the modules I required to be loaded in order to make the wifi work were the following:
I have also uninstalled wicd since Slackware 14 has Network Manager which I now use and which appears to be very reliable compared with wicd under Slackware 13.37. Your use of wicd-curses suggests that you want to use a network management tool with a CLI mode - I don't know if Network Manager has such a tool or not.

Just checked - there is a CLI tool supplied with Network Manager - nmcli which can be used to provide lists of devices and connections etc.

Thanks, I seem to have fixed the wireless driver part of my problem. Still can't get wicd-curses to see networks. Now I just need to figure out how to use nmcli.
