完成答案：

如果您的控制器并没有支持UAS，Linux内核是一种足以告诉你这样：

$ dmesg | grep "UAS"

[58669.959610] usb 4-2: USB controller 0000:03:00.0 does not support streams, which are required by the UAS driver.

[58669.959613] usb 4-2: Please try an other USB controller if you wish to use UAS.

同样，lsusb显示了bInterfaceProtocol 98的一行，但是它是空的：

$ lsusb -v -d 0080:a001 | grep -i interface

bDeviceClass 0 (Defined at Interface level)

bNumInterfaces 1

Interface Descriptor:

bInterfaceNumber 0

bInterfaceClass 8 Mass Storage

bInterfaceSubClass 6 SCSI

bInterfaceProtocol 80 Bulk-Only

iInterface 0

Interface Descriptor:

bInterfaceNumber 0

bInterfaceClass 8 Mass Storage

bInterfaceSubClass 6 SCSI

bInterfaceProtocol 98

iInterface 0
