I can help you fix both of these problems in one fell swoop because I just installed my rt2870sta-based wireless card yesterday.
To get Internet access, you must blacklist the rt2800usb driver. This allows the rt2870sta driver to work. You won't get any of those error messages anymore because the module isn't being loaded. I actually was just having issues with the 'driver already registered, aborting...' messages as well, and I just fixed it. I had entered 'rt2870sta' to the end of my /etc/modules file and this ended up being the problem. Remove any entry for 'rt2870sta' from your /etc/modules and those related error messages should disappear. -- Driver (rt2870) and usbcore error messages during boot process https://bugs.launchpad.net/bugs/441303 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
