 Posted: Thu Jan 10, 2008 6:21 pm Post subject: Udev won't give me /dev/ttyS0 (Solved) |
 |
|
I need this node for a serial tablet stylus. and the udev used to give me all 4 standard serial ports in /dev.... now it only gives me ttyS1, ttyS2, and ttyS3. This is a HP tabletPC and the /dev/ttyS0 is needed for the digitizer and pen. I think I lost the node after an emerge -uDav world fiasco, but it also might have happened after a kernel upgrade. here is my dmesg output...

I can get the node (/dev/ttyS0) to show up w/ a custom udev rule...
| Code: | #No Legacy Serial ports /etc/udev/rules.d/10-local.rules
ACTION=="add", DEVPATH=="/devices/platform/serial8250/*", OPTIONS="ignore$
ACTION=="remove", DEVPATH=="/devices/platform/serial8250/*", OPTIONS="ignore$
|
However this causes Hald to fail... I'm at a loss as to what has changed to get this node written correctly from Udev with out a custom rule... I never needed it before, I just Had to get the port working to test the Xdriver for the pen.
Any ideas?
