It may be as simple as CDC-ACM retrying without a delay or giving up. Or this is in usbcore. Could you initially try without CDC-ACM, so we can narrow this down? And tehn we can try with dynamic debugging or thought what can be done. And thank you for identifying the root cause for the malfunction. Yet you are clearly right that even such a device should not crash the kernel. Regards Oliver
