Hi, I tried attaching my motorola t720 cellphone and got some errors:
First of all, messages like this appeared on the console: Sep 2 22:47:26 tequila kernel: usb 1-1.3: new full speed USB device using address 9 Sep 2 22:47:26 tequila kernel: usb 1-1.3: device not accepting address 9, error -71 Sep 2 22:47:26 tequila kernel: usb 1-1.3: new full speed USB device using address 10 Sep 2 22:47:27 tequila kernel: usb 1-1.3: device not accepting address 10, error -71 Finally, I got this in my syslog: 2 22:34:07 tequila kernel: drivers/usb/class/cdc-acm.c: v0.23:USB Abstract Control Model driver for USB modems and ISDN adapters Sep 2 22:34:23 tequila kernel: usb 1-1.3: new full speed USB device using address 8 Sep 2 22:34:24 tequila kernel: usb 1-1.3: device not accepting address 8, error -71 Sep 2 22:34:24 tequila kernel: usb 1-1.3: new full speed USB device using address 9 Sep 2 22:34:24 tequila kernel: Unable to handle kernel NULL pointer dereference at virtual address 00000005 Sep 2 22:34:24 tequila kernel: printing eip: Sep 2 22:34:24 tequila kernel: d0c18b58 Sep 2 22:34:24 tequila kernel: *pde = 00000000 Sep 2 22:34:24 tequila kernel: Oops: 0000 [#1] Sep 2 22:34:24 tequila kernel: PREEMPT Sep 2 22:34:24 tequila kernel: CPU: 0 Sep 2 22:34:25 tequila kernel: EIP: 0060:[pg0+277281624/1069895680] Tainted: P Sep 2 22:34:25 tequila kernel: EFLAGS: 00010246 (2.6.5) Sep 2 22:34:25 tequila kernel: EIP is at acm_probe+0x78/0x530 [cdc_acm] Sep 2 22:34:25 tequila kernel: eax: c25647c0 ebx: 00000000 ecx: c5859f60 edx: 00000000 Sep 2 22:34:25 tequila kernel: esi: cf4b8bc0 edi: c1c329c0 ebp: cdc37400 esp: cf7f3de8 Sep 2 22:34:25 tequila kernel: ds: 007b es: 007b ss: 0068 Sep 2 22:34:25 tequila kernel: Process khubd (pid: 92, threadinfo=cf7f2000 task=cfa271e0) Sep 2 22:34:25 tequila kernel: Stack: c25647c0 00000000 cbb573c0 000081a4 00000000 c018909d cf7f3e04 413783 d0 Sep 2 22:34:25 tequila kernel: ca345440 cbb573c0 ca345440 ca345440 c0167d22 ca345440 c0393fd0 ca3454 40 Sep 2 22:34:25 tequila kernel: 00000000 c25647c0 d0c19ee0 cf4b8bc0 ffffffed cf4b8c2c d0870081 cf4b8b c0 Sep 2 22:34:25 tequila kernel: Call Trace: Sep 2 22:34:25 tequila kernel: [sysfs_new_inode+93/176] sysfs_new_inode+0x5d/0xb0 Sep 2 22:34:25 tequila kernel: [dput+34/528] dput+0x22/0x210 Sep 2 22:34:25 tequila kernel: [pg0+273444993/1069895680] usb_probe_interface+0x61/0x80 [usbcore] Sep 2 22:34:25 tequila kernel: [bus_match+63/112] bus_match+0x3f/0x70 Sep 2 22:34:25 tequila kernel: [device_attach+65/160] device_attach+0x41/0xa0 Sep 2 22:34:25 tequila kernel: [bus_add_device+91/160] bus_add_device+0x5b/0xa0 Sep 2 22:34:25 tequila kernel: [device_add+161/304] device_add+0xa1/0x130 Sep 2 22:34:25 tequila kernel: [pg0+273470726/1069895680] usb_set_configuration+0x1d6/0x270 [usbcore] Sep 2 22:34:25 tequila kernel: [pg0+273449193/1069895680] usb_new_device+0x249/0x3c0 [usbcore] Sep 2 22:34:25 tequila kernel: [pg0+273455637/1069895680] hub_port_connect_change+0x175/0x280 [usbcore] Sep 2 22:34:25 tequila kernel: [pg0+273456618/1069895680] hub_events+0x2ca/0x340 [usbcore] Sep 2 22:34:25 tequila kernel: [pg0+273456781/1069895680] hub_thread+0x2d/0xf0 [usbcore] Sep 2 22:34:25 tequila kernel: [ret_from_fork+6/20] ret_from_fork+0x6/0x14 Sep 2 22:34:25 tequila kernel: [default_wake_function+0/32] default_wake_function+0x0/0x20 Sep 2 22:34:25 tequila kernel: [pg0+273456736/1069895680] hub_thread+0x0/0xf0 [usbcore] Sep 2 22:34:25 tequila kernel: [kernel_thread_helper+5/20] kernel_thread_helper+0x5/0x14 Sep 2 22:34:25 tequila kernel: Sep 2 22:34:25 tequila kernel: Code: 80 7a 05 0a 75 b7 80 7a 04 01 76 b1 8b 49 0c 89 4c 24 40 8b Kernel is a self-compiled 2.6.5 on a debian system. Other usb devices (as my touchstream lp keyboard) work perfect. And back a year ago, I managed to attach the phone under kernel 2.4, with a small patch to register the vendor/product ID I found here: http://www.qbik.ch/usb/devices/showdev.php?id=1021 Any suggestions?
