您好，
dm368 启动时的log中有：
Starting udev
[ 9.620000] musb_hdrc: version 6.0, cppi-dma, peripheral, debug=0
[ 9.810000] musb_hdrc: USB Peripheral mode controller at fec64000 using DMA, IRQ 12
[ 18.720000] FAT: bogus number of reserved sectors
[ 18.720000] VFS: Can't find a valid FAT filesystem on dev mmcblk0.
Remounting root file system...
logger: mount: mount point /proc/bus/usb does not exist
我已经在内核配置中关掉了usb master，这个musb_hdrc为什么要这么长的时间，谢谢！
