Hi, I recently purchased a 802.11n wireless USB device. Specifically, its the Trendnet TEW 649UB [1]. I believe it uses the Realtek RTL8192SU chip. I'm running Ubuntu 9.10 64bit. The current kernel is Linux 2.6.31-15. When I plug-in the device, it doesn't work. dmesg shows the following logs: ------------------------------------------------------------------------------------------------------------------------- [ 1754.202557] usb 2-2: new high speed USB device using ehci_hcd and address 4 [ 1754.363248] usb 2-2: configuration #1 chosen from 1 choice [ 1754.410823] ieee80211_crypt: module is from the staging directory, the quality is unknown, you have been warned.

The last error keeps looping for a few times. When I place the firmware in the /lib/firmware/RTL8192SU directory, and plugin the device, I get a kernel panic. Is there a chance that I could get this device working sooner than later? If so, where do I get the source? Also, is there a way that I could help speed up the development of this driver? I have already tried ndiswrapper but unfortunately, the 64bit driver causes ndiswrapper to segfault. Thanks!
