We should check the return of usb_new_device() so that if no USB device is found, we print out the right message rather than always saying "new usb device found".
Signed-off-by: Bryan Wu bryan.wu@analog.com Signed-off-by: Mike Frysinger vapier@gentoo.org --- this is against u-boot-usb.git ... apparently that has a lot of whitespace cleanups in it. i'm guessing those will be merged into mainline after the next release ? or should i redo the patch against u-boot.git ?
