以下就是运行dmesg后与USB有关的信息:
usb 1-1: new high speed USB device using address 2
usb 1-1: control timeout on ep0out
ehci_hcd 0000:00:10.4: Unlink after no-IRQ? Different ACPI or APIC settings may help.
usb 1-1: control timeout on ep0out
usb 1-1: device not accepting address 2, error -110
usb 1-1: new high speed USB device using address 3
usb 1-1: control timeout on ep0out
usb 1-1: control timeout on ep0out
usb 1-1: device not accepting address 3, error -110
我不知道问题出在哪儿!
