Hello,
rt2500usb is broken since kernel 2.6.29. It has been discussed before but
never solved:
http://rt2x00.serialmonkey.com/phpBB/viewtopic.php?f=4&t=4834
https://bugzilla.redhat.com/show_bug.cgi?id=484888
I have Asus WL-167G and it really does not work. Scanning works, association
too but no packets can be sent (looks like receive works because tcpdump
shows packets from other machines). DHCP fails (No DHCPOFFERS received).
The problem is caused by this patch:
rt2x00: Implement HW encryption (rt2500usb)
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=dddfb478b2...
Removing it from 2.6.29 restores the functionality.
