Edgerouter4 hardware fault or bug ?

Hello,
I bought the following 4g mobile modem:

and an Ubiquiti EdgeRouter4 and on this I installed openbsd 6.9.
Then I connected the 4g modem to the router but the device seems faulty, because there are continuous disconnect and reconection of the usb device.
The following video show what I mean:

Here is what I did to understand if the problem depends of the 4g mobile modem or the router:
- I tried to connect the 4g usb mobile modem to a linux machine and it works.
- I tried to connect the 4g usb mobile modem to an openbsd x86 laptop and it works
- I tried to connect a usb pendrive to the router and it works
Then in my opinion it's a bug on openbsd drivers.
If this is true what should I do ?
And for last what's your opinion ?

Thanks
Cord.
