Red Hat Bugzilla – Bug 147002
usbserial not part of default udev configuration
Last modified: 2007-11-30 17:10:59 EST
Description of problem:
When I plug in my handy-dandy USB to serial/parallel box (Keyspan
UPR-112 if it matters, but this seems to apply to all such devices),
the parallel device /dev/usb/lp0 is automatically created just fine.
The same is not true of /dev/usb/ttyUSB0, but it should be.
Version-Release number of selected component (if applicable):
udev-039-10.FC3.6 (installed Fedora Core 3 from CD, then applied all
updates to 3 Feb via yum. So I have hal, etc, in case that matters).
The problem was fixed by adding the following to
/etc/udev/rules.d/60-local.rules . This bug is a request to have such
a line added to the default configuration.
BUS="usb", KERNEL="ttyUSB[0-9]*", NAME="usb/%k"
(assuming, of course, that my understanding is right about how all
this udev stuff is supposed to work).
what about the created /dev/ttyUSB* ?
The default created /dev/ttyUSB* has different permissions/owner/group
than the ones which I get with the rule I posted, but adding myself to
group uucp took care of it.
Not that I'm going to claim that I tried to put it in /dev/usb for
reasons of permissions. I just didn't know to look in /dev/ttyUSB0.
So this bug should be closed (unless of course there is some
documentation which could have pointed me in the right direction, but
I'm not sure there's any place I looked which could have done so).
