I still haven't had the time to do another edit session to go over
everyone's comments. I did try to launch darktable today and had it
block again. Here's the last few lines of strace:
mprotect(0x7363000, 4096, PROT_READ) = 0
mprotect(0x10f6000, 4096, PROT_READ) = 0
munmap(0xb7721000, 92150) = 0
openat(AT_FDCWD, "/dev/bus/usb",
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 5
getdents(5, /* 4 entries */, 32768) = 64
close(5) = 0
openat(AT_FDCWD, "/dev/bus/usb",
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 5
getdents(5, /* 4 entries */, 32768) = 64
getdents(5, /* 0 entries */, 32768) = 0
close(5) = 0
openat(AT_FDCWD, "/dev/bus/usb/002",
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 5
getdents(5, /* 3 entries */, 32768) = 48
open("/dev/bus/usb/002/001", O_RDWR) = -1 EACCES (Permission denied)
open("/dev/bus/usb/002/001", O_RDONLY
It seems darktable is blocking trying to open the root USB device.
This may very well be a bug in the virtualbox USB support. There's
nothing attached to USB:
$ lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Running with "-d all" doesn't seem to give any more useful info
$ darktable -d all
