有一个u盘, s3c2416和电脑都可以读写, 但是用V3s出现这个提示,

格过了, 还是不行

供电应该没有问题,
另一个U盘正常。
有没有办法解决?

按这个做法,然而并没有什么卵用。

Re: 有一个u盘, s3c2416和电脑都可以读写, 但是用V3s不能读写

不过还是有点卵用, 我写N就好了。

echo N > /sys/module/usbcore/parameters/use_both_schemes
echo Y > /sys/module/usbcore/parameters/old_scheme_first

这样之后, 我手里的两个U盘都可以读写了,但是会不会引起别的问题还不知道。

# echo N > /sys/module/usbcore/parameters/use_both_schemes
# echo Y > /sys/module/usbcore/parameters/old_scheme_first

我这里5个U盘, 3个OK, 还有两个插上去控制台毛反应都没有,U盘在电脑都是正常的。
感觉要成背锅侠了。

看来3楼的办法只可以解决一部分问题, 不能解决全部的问题。
