Syzbot doesn't test real devices.  It tests emulations, and the emulated
devices usually behave very strangely and in very peculiar and
unexpected ways, so as to trigger bugs in the kernel.  That's why the
USB devices you see in syzbot logs usually have bizarre descriptors.

Do you mean I have to debug for a device which doesn't exist?
I don't understand why I must consider a fake device
which provide unexpected USB descriptor deliberately?
