使用主板USB2.0连接的设备在Ubuntu14.04中不能工作,尽管它们在GRUB 2中工作得很好。
当我连接一个键盘时,dmesg
会沿着这些思路吐露出一些东西:
usb 7-3: new full-speed USB device number 6 using ohci-pci
usb 7-3: device descriptor read/64, error -32
usb 7-3: device not accepting address 6, error -32
usb 7-3: new full-speed USB device number 7 using ohci-pci
usb 7-3: device not accepting address 7, error -32
usb 7-3: new full-speed USB device number 8 using ohci-pci
usb 7-3: device not accepting address 8, error -32
usb 7-3: new full-speed USB device number 7 using ohci-pci
usb 7-3: device descriptor read/8, error -32
usb 7-3: device descriptor read/all, error -32
usb usb7-port3: unable to enumerate USB device
将相同的键盘连接到主板的USB3.0可以很好地工作。
