The log is attached. To make sure this value is actually changed, I added two debug prints in u_audio.c. You can see the two printk's in the attached log. for (i =3D 0; i < params->req_number; i++) { printk("REQ NUM (c) %d\n", i); // <=3D=3D=3D Added if (!prm->reqs[i]) { printk("ALLOC %d\n", i); // <=3D=3D=3D Added req =3D usb_ep_alloc_request(ep, GFP_ATOMIC); The symptom is still the same, getting BNA interrupt. The log is attached. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
