Must be. Here's something else you can do. Make sure CONFIG_DEBUG_FS is also enabled in the configuration. Then mount a debugfs filesystem, say on /sys/kernel/debug, and post a copy of the /sys/kernel/debug/usb/ehci/ar71xx/registers file (the pathname may be slightly different from this, but it will be similar). Do this after a failed detection, while the device is still plugged in.
