LinuxQuestions.org - [SOLVED] Ralink chipset works in Ubuntu Jaunty, not Karmic beta

I have a USB wireless adapter, the Rosewill RNX-EasyN1 (networkmanager lists it as a "Ralink 802.11 n WLAN") that worked fine in Jaunty but not Karmic. The driver (rt2870sta or rt3070sta or something like that) is still around, but plugging it in doesn't let me connect. It shows the device in networkmanager but I don't think it gets its own file in /dev. Running dmesg shows the following output after I plug it in:

Code:

So, what is going wrong, or where should I file a bug on launchpad?
