首先你通过设备名找到设备Bus和Device number:
$ lsusb
...
Bus 002 Device 005: ID xxxx:yyyy MyDeviceManufacturer
...
Then look at the USB tree and find your device (mine was Bus 2, Dev 5):
然后查看USB 树找出想查看的设备:
$ lsusb -t
...
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 5000M
|__ Port 2: Dev 5, If 0, Class=Mass Storage, Driver=uas, 5000M
|__ Port 4: Dev 3, If 0, Class=Mass Storage, Driver=usb-storage, 5000M
...
从Driver段可以看出是否使用的是uasp,
如果没启用,显示就想上面Dev 3那样。
如果是arm开发板,可以
cat /sys/kernel/usb/devices
来查看Driver段。
