혹시나 해서 jsm583 칩으로 만들어진 리뷰안 m.2 to USB3.0을 이용해서 사용이 가능한가 했는데 역시나(?) 안되는 듯.
usb 자체가 pcie bridge로 작동하는게 아니라 usb storage class로 잡혀 버리는 듯.

PCIe Bridge는 맞지.. storage solution 이라 그렇지...(!!)
JMicron announced its JMS583 (USB 3.1 to PCIe Bridge controller) received USB-IF Logo Certification The JMS583 is mainly used in the development of PCIe/NVMe related products, such as converting a PCIe/NVMe SSD to a superspeed plus USB interface portable mobile storage solution. This will significantly reduce the cost and time needed for PCIe/NVMe SSD production in the factory, which will also accelerate the end-product’s time-to-market. JMicron believes that the market will always strive for extreme high-speed, low power consumption, thin and light solutions for external storage products. |

USB 쪽을 Mass stroage class로 구현되어서 발생한 일인듯하다.
