Hello, I am experiencing problems with USB while trying to download pictures from various digital cameras. The system where I encounter the problem is Fedora Core 2 with a self compiled Kernel 2.6.8.1. When I plug in a camera it gets detected and identified. Gphoto2 (2.1.4) however just hangs and can't even be killed through signal 9. When I strace gphoto2 I am able to interrupt. Afer that it is not possible to remove the kernel module ohci_hcd, though. When I am booting Fedora with a 2.4 Kernel, it works. I've tried other 2.6 versions with no success, too. On the same box Suse 9.1 (Kernel 2.6.4-52) is able to download the pics. I've created a trace of gphoto2 during its hang, maybe it is helpful: gphoto2 D C03F70E0 0 23442 10681 (NOTLB) c6aafdb0 00000086 c33c53b0 c03f70e0 00000246 c79b f800 c14243e0 c0008280 00000000 c6aafdb8 00000246 c3c59800 c08dc6e0 00000000 0000650f 8fe10ab6 000056ea c33c5588 c6aafe94 c6aafe90 c6aae000 c6aafe20 c030efe3 00000010 Call Trace: [<c030efe3>] wait_for_completion+0x103/0x2c0 [<c883ec7a>] usb_start_wait_urb+0x11a/0x160 [usbcore] [<c88451f6>] proc_bulk+0x136/0x260 [usbcore] [<c8846fde>] usbdev_ioctl+0x5be/0x760 [usbcore] [<c01817e2>] file_ioctl+0x62/0x160 [<c018199c>] sys_ioctl+0xbc/0x220 [<c01065e1>] sysenter_past_esp+0x52/0x71 My USB hardware is AMD756. I know it has lots of bugs but there should be workarounds in the driver (2.4 and 2.6). Any hints or suggestions for further debugging? thanks Oliver ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
