LINUX内核版本2.6.21，使用我的两块板子（cpu均为s3c2416），一块作为USB HOST,一块作为USB DEVICE。现在情况是将DEVICE设备连到HOST上出错，错误消息如下：
[[email protected] /]# usb 1-1.1: new full speed USB device using s3c2410-ohci and address 3
usb 1-1.1: device descriptor read/64, error -62
usb 1-1.1: device descriptor read/64, error -62
usb 1-1.1: new full speed USB device using s3c2410-ohci and address 4
usb 1-1.1: device descriptor read/64, error -62
usb 1-1.1: device descriptor read/64, error -62
usb 1-1.1: new full speed USB device using s3c2410-ohci and address 5
usb 1-1.1: device not accepting address 5, error -62
usb 1-1.1: new full speed USB device using s3c2410-ohci and address 6
usb 1-1.1: device not accepting address 6, error -62
可确定HOST侧是好的（因为我连上U盘可正常识别），看来问题应该在DEVICE这边。
HOST和DEVICE侧的驱动都是移植的友坚开发板自带的驱动。
由上述消息大概问题出在哪，我现在都没有方向了。请指教。
