U盘无法识别
今天把联想4G的U盘插在USB口,无法自动挂载,
fdisk -l了,也没有该u盘的任何信息。接着:
root@debian:~# dmesg | tail
[ 5753.208083] usb 5-1: device descriptor read/64, error -71
[ 5753.424105] usb 5-1: new full speed USB device using uhci_hcd and address 4

[ 5786.722372] i2c i2c-1: sendbytes: NAK bailout.
出现了这个错误,网上搜了一下,也没有找到什么有用的信息。是不是flash里面烧的程序有错呢?
还有新买的一个磊科无线网卡(USB接口,插在台式机后面的USB接口上),在开机启动的过程中,也会出现类似的情况,然后启动后鼠标键盘全部失效...拔出来重新插就OK了,而且换一个USB插口,在启动过程中就ok。
PS:这个U盘不是正品的(虽然是正品的价买的,被人骗了@_@)
