I get either a "acm: probe of 3-3:2.1 failed with error -5" but it works or a Unable to handle kernel NULL pointer dereference at virtual address 00000008 printing eip: c023d9c3 *pde = 00000000 Oops: 0000 [#1] CPU: 0 EIP: 0060:[usb_driver_claim_interface+67/112] Tainted: P EFLAGS: 00010202 EIP is at usb_driver_claim_interface+0x43/0x70 eax: c02ffe72 ebx: dddcf200 ecx: 00000004 edx: dddfa2ec esi: dddfa120 edi: 00000000 ebp: dddce3c0 esp: c15b1dd8 ds: 007b es: 007b ss: 0068 Process khubd (pid: 5, threadinfo=c15b0000 task=ddf8e040) Stack: c030a460 c02ff409 c02ffe72 00001388 dddcf200 c025141c c033a8e0 dddfa2ec dddce3c0 dddce3d8 00000007 00000094 dddcf200 00000000 00000020 dddfa120 c1796ac0 c1796ad4 dddddc00 c033a968 c033a900 c033a8e0 dddfa240 c023d713 Call Trace: [acm_probe+1228/1408] acm_probe+0x4cc/0x580 [usb_probe_interface+115/160] usb_probe_interface+0x73/0xa0 [bus_match+63/112] bus_match+0x3f/0x70 [device_attach+65/160] device_attach+0x41/0xa0 [bus_add_device+91/160] bus_add_device+0x5b/0xa0 [device_add+167/272] device_add+0xa7/0x110 [usb_set_configuration+456/576] usb_set_configuration+0x1c8/0x240 [usb_new_device+690/992] usb_new_device+0x2b2/0x3e0 [hub_port_connect_change+461/816] hub_port_connect_change+0x1cd/0x330 [hub_events+773/848] hub_events+0x305/0x350 [hub_thread+53/224] hub_thread+0x35/0xe0 [default_wake_function+0/48] default_wake_function+0x0/0x30 [hub_thread+0/224] hub_thread+0x0/0xe0 [kernel_thread_helper+5/12] kernel_thread_helper+0x5/0xc
