从你那里我能看出什么输出dmesg
,超级速度肯定已启用:
925 [ 2367.435312] usb 4-2: new SuperSpeed USB device number 2 using xhci_hcd
但你会遇到一些失败:
931 [ 2367.452508] usb 4-2: Enable of device-initiated U1 failed.
932 [ 2367.452666] usb 4-2: Enable of device-initiated U2 failed.
933 [ 2367.453158] usb 4-2: Enable of device-initiated U1 failed.
934 [ 2367.453310] usb 4-2: Enable of device-initiated U2 failed.
...
937 [ 2367.516876] usb 4-2: Enable of device-initiated U1 failed.
938 [ 2367.517032] usb 4-2: Enable of device-initiated U2 failed.
您还会在输出lsusb -v
:
131 bDescriptorType 4Couldn't open device, some information will be missing
132 Couldn't open device, some information will be missing
现在,很抱歉,因为我必须告诉你:我怀疑这是硬件故障 - 外部硬盘可能有问题,也可能是电缆松动。为确保万无一失,请尝试在另一个系统/机器上检查它们(硬盘和电缆)。
