X301 SATA NAS Storage Expansion Board - UASP issue

Hi,

I have https://geekworm.com/products/x301 attached to a RPI Zero 2W, with latest Raspbery PI OS. On the product page it says:
- Supports USB Attached SCSI Protocol (UASP)
however when I look at the system it shows as USB mass storage (BOT), not UASP:
```
root@raspberrypi:~# lsusb -t
/:  Bus 001.Port 001: Dev 001, Class=root_hub, Driver=dwc_otg/1p, 480M
    |__ Port 001: Dev 002, If 0, Class=Hub, Driver=hub/4p, 480M
        |__ Port 001: Dev 003, If 0, Class=Mass Storage, Driver=usb-storage, 480M
        |__ Port 002: Dev 004, If 0, Class=Human Interface Device, Driver=usbhid, 1.5M
        |__ Port 003: Dev 005, If 0, Class=Vendor Specific Class, Driver=asix, 480M
```
Where it says Driver=usb-storage it should have said Driver=uas

Any idea how to make it recognize as UASP instead of BOT?

Thanks!

The PI ZERO 2W only supports USB 2.0, so it does not support the UASP protocol. However, the X301 hardware itself supports UASP. Please understand.
