Hi, I founded the trouble : rt2500usb should NOT be loaded at the same time that rt73usb : the two drivers are different.
How to fix it : $ cd /lib/modules/`uname -r`/ubuntu/wireless/rt2x00 $ sudo mv rt2500usb.ko rt2500usb.ko_bak $ sudo depmod -a Then unplug your device, remove all remaining rt* module : $ sudo rmmod rt73usb rt2x00usb rt2x00lib rt2500usb Plug your device. It should work. In fact, there are bad vid:pid identifiers in rt2500, that should only be in one module. I put bellow the list of duplicate identifiers : v148Fp2573 v050Dp705Ad v050Dp7050d Mine is v148Fp2573 and should only be rt73usb. ** Changed in: linux-ubuntu-modules-2.6.22 (Ubuntu) Sourcepackagename: None => linux-ubuntu-modules-2.6.22 Assignee: (unassigned) => Ben Collins (ben-collins) Status: New => Confirmed -- [Gutsy] Ralink 2573 usb adapter does not work out of the box https://bugs.launchpad.net/bugs/139070 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
