USB驅(qū)動壓力測試問題

thzhr2009

cpu：BCM5892
linux2.6.32.9
usb otg驅(qū)動加載，外接U盤。壓力測試方法：

load OTG driver modules
sleep 10
mount /dev/sda1 /mnt/usbd
ls /mnt/usbd
umount /mnt/usbd
unload OTG driver modules
loop again
循環(huán)測試兩千多次后出錯:
mount: mounting /dev/sda1 on /mnt/usbd failed: No such file or directory
umount: cannot umount /mnt/usbd: Invalid argument
找不到usb的設(shè)備節(jié)點/dev/sda1了，有沒有遇到類似情況的朋友提供幫助。
