There was a problem hiding this comment.
Reference to others doing something similar, https://github.com/OpenXT/vusb-daemon/blob/ed721b3caa4b0fc93a54fac6b86cad17228ce842/src/udev.c#L383-L387
It's using 10 because the devnum and busnum are base 10 vs the others are base 16

Hello,
this commit exposes the devnum and busnum to the library.
I use this to get the path for the device on ubuntu for udev.
Before this change the
device.deviceAddressanddevice.locationIdwere set to zero.Related to #8 and #51
