I use STM32CubeIDE 1.16.0 to do project and use STM32H743.when my code is over 512K, I re-write ld file,but download is failed.But I use STM32CubeProgrammer to download the same elf file,it worked!!! So what's wrong about it ?

I will try what you said.USB reset status can be received.but descriptor is not.

We have a Timer interrupt and priority is very high, the interrupt time is 100us.we do not want usb interrupt disturb it.I had tried the method like you said.But when the host send get descriptor command, device wasn't response.
