m210 v1 and v2 are great products. However, there are some problems when used with manifold2.
On m210 V2(RTK, nonRTK both), The problem I encountered is that depending on the USB mode, the video(x5s) cannot be received at crystal-sky display.
1.When changing the USB mode to PC mode using the slide switch, manifold can detect m210 USB / but, video from gimbal camera(x5s) not display on crystal-sky display with ERROR 'sd card is not enough'

2. If setting the USB mode to mobile mode,
manifold can not detect m210 USB / video display on crysta-sky display


but, on m210 V1 with same manifold it didn't happened.
Even if you connect the m210 and the computer (Linux), it happens again.
ofcourse i activated every flights, update firmwares/apps,  enable USB port to fly. there are enought volumes in SD card.


Are there any solutions to solve this USB mode problem???

This is not an error,   it related with the solution that designed.

USB mode  -   this means the camera storage would treat as a SD card or so,  no  live stream at this time since the ethnet is break.
ETH mode -  normally,  it would be this mode,  usb would be act as ethnet, the live stream can transfer normally.
