Hello,
I've got a Canon digital camera set up and working with gphoto2 via
devfs+devd but it's not elegant/clean enough:
attach 0 {
device-name "ugen[0-9]+";
match "vendor" "0x0123";
match "product" "0x3210";
match "sernum" "1234567890";
action "devfs rule -s 10 add 100 path $device-name* user joe; \
devfs rule -s 10 add 200 path usb[0-9] user joe; \
devfs rule -s 10 applyset";
};
Problem with this solution is that it changes owner for all /dev/usb
files i.e. usb, usb0, usb1, usb2 and usb3.
How can I check exactly which /dev/usb* entry corresponds to my camera?
And by the way /dev/usb3 means port 3, hub 3 or what are they?
Tried with:
usb_number=`sysctl dev.ugen.0.%location | cut -d '=' -f 2` but it turns
out that it's not what I'm looking for because sometimes when it returns
"2" then I still need write access to just /dev/usb3.
Any ideas please?
Michal
