Describe what you want to implement and what the issue & the steps to reproduce it are:

Does the ML500-75M camera not support USB2.0? My embedded board only has a USB2.0 interface. Works fine on X86X64 host. Does ML500-75M only work with USB 3.0 hardware interface?

Is your camera operational in Basler pylon viewer on your platform

no. You can use a dart camera at USB 2 port.

no. You can use a dart camera at USB 2 port.

But prompt： The device cannot be operated on an USB 2.0 port. The device requires an USB 3.0 compatible port

What causes? The USB3.0 interface works normally. The above prompt appears on the USB2.0 interface....
