根据这个方法配置的USB的内核,但打印出来还是不对,U盘插上去之后显示如下:
usb 1-2: new full speed USB device using s3c2410-ohci and address 4
usb 1-2: device descriptor read/64, error -62
usb 1-2: device descriptor read/64, error -62
usb 1-2: new full speed USB device using s3c2410-ohci and address 5
usb 1-2: device descriptor read/64, error -62
usb 1-2: device descriptor read/64, error -62
usb 1-2: new full speed USB device using s3c2410-ohci and address 6
usb 1-2: device not accepting address 6, error -62
usb 1-2: new full speed USB device using s3c2410-ohci and address 7
usb 1-2: device not accepting address 7, error -62
请问这是什么原因造成的?
