Hi,
I have 3 the same devices of the same brand, e.g. their vendor, product
and version fields in struct hiddev_devinfo are all the same. Two of
them are on the same bus, the third on some other bus.
USB PORT 1 USB PORT 2
| | |
| device B device C
device A
Using udev these devices get a /dev/usb/hiddev[0-15] node allocated.
My question now is: will each device always have the same node? Will
device A always get for example /dev/usb/hiddev0? and C always
/dev/usb/hiddev2?
And if that is not the case, how can I then find those? Will it work if
I use busnum, devnum and ifnum?
