Check the "dmesg". If you see something like: usb0: 12MBps Full Speed USB v1.0 usb1: 12MBps Full Speed USB v1.0 usb2: 12MBps Full Speed USB v1.0 usb3: 480MBps High Speed USB v2.0 Then you are using the new stack. Make sure that you are using the latest version. Hence you needed to remove "if_ural.c" it does not sound like you are using the latest version. Do a "svn update" again, build a new package, install that, and build a new kernel. --HPS
