Hipad pro and OTG support

Icannot connect a FAT32 HDD to the hipad pro
No usb notification on the screen
If I connect the same disk to a samsung tablet with android 8 or 2 different phones it works well i can see all my files and,access them. It is not a connector problem i use the same connector fir all these tests
When connected to the hipad pro the disk flashes indefinitely then thé tablet crashes a chuwi 3D appears on the screen nothing happen
If I disconnect thé disk it reboot to thé standby screen
Anyone with same problem ?
