Any scanning program, like simple-scan or xsane, hangs when trying to do anything with this printer (the process becomes defunct/zombie). The backtrace is: #0 ioctl () at ../sysdeps/unix/syscall-template.S:81 #1 0x00007fffecd80b40 in pp_probe_devices (lst=0xb <error: Cannot access memory at address 0xb>, lst@entry=0x7fffffff5790 "", lst_size=-2147192681, lst_size@entry=16144, cnt=0x7fffffff4d9c, cnt@entry=0x7fffffff5468) at io/hpmud/pp.c:1228 #2 0x00007fffecd78661 in hpmud_probe_devices (bus=bus@entry=HPMUD_BUS_ALL, buf=buf@entry=0x7fffffff56a0 "direct hp:/usb/Photosmart_C4200_series?serial=MY798KP16D04VP \"HP Photosmart C4200 series\" \"HP Photosmart C4200 series USB MY798KP16D04VP HPLIP\" \"MFG:HP;MDL:Photosmart C4200 series;CLS:PRINTER;DES:Phot"..., buf_size=buf_size@entry=16384, cnt=cnt@entry=0x7fffffff5468, bytes_read=bytes_read@entry=0x7fffffff546c) at io/hpmud/hpmud.c:600 #3 0x00007fffed3796c5 in DevDiscovery (localOnly=localOnly@entry=0) at scan/sane/hpaio.c:278 #4 0x00007fffed379cd9 in sane_hpaio_get_devices (deviceList=0x7fffffff9758, localOnly=0) at scan/sane/hpaio.c:359 #5 0x00007ffff7bd6427 in sane_dll_get_devices (device_list=0x69fb80, local_only=0) at dll.c:1058 According to strace, the last two syscalls are: open("/dev/parport0", O_RDONLY|O_NOCTTY) = 11 ioctl(11, PPGETMODES, 0x7fffbe27f54c) ... and the last one (ioctl) hangs (i.e. strace didn't print even the closing bracket). This happens even when the device is NOT plugged via USB.
