USB 305 Drivers?

Hey, I’ve installed a Sierra Wireless USBConnect Lightning on a Acer Asprire One along with AT&T Communication Manager. Well, CM installed fine, but said that there was, “No Wireless Device Detected”. Ok,so I check device manager for the Aircard and there are yellow ?s next to the USB 305. Alright, I need to download the drivers for USB 305, but the software that came with the USBConnect (CM and Tru-Install) don’t have the drivers. So, I went out on the web and couldn’t find a single site with a download for USB 305…HELP! Oh, before I started searching for drivers, I re-installed CM and Tru-Install; same results. Oh, I also installed the aircard on a different computer and everything works fine…
