Hi all,
Sorry if this offtopic is this list, in such case please point me to
correct location.
I am tring to write a rule that will create a specific char device for
every different USB connector (this is an embeeded application, and
the use case is: "please connect the device to the upper connector").
I am using 173 on 2.6.32/arm.
I have two different USB controllers which can be identified by
ATTRS{serial}=="musb_hdrc" and ATTRS{serial}=="ehci-omap.0"
First try:
KERNEL=="hidraw[0-9]*", ATTRS{serial}=="musb_hdrc", SYMLINK+="aaaaaaaaaa"
KERNEL=="hidraw[0-9]*", ATTRS{idVendor}=="c1ca", SYMLINK+="bbbbbbbbbbb"
OK, works. I see both links generated. Now I need to combine them:
KERNEL=="hidraw[0-9]*", ATTRS{idVendor}=="c1ca",
ATTRS{serial}=="musb_hdrc", SYMLINK+="cccccccccc"
KERNEL=="hidraw[0-9]*", ATTRS{serial}=="musb_hdrc",
ATTRS{idVendor}=="c1ca", SYMLINK+="dddddddddd"
None working. What I think in happening is that the idVendor of the
USB hub is matched and not of the device. I need to match:
ATTR{idVendor}=="c1ca" and some parent has ATTRS{serial}=="musb_hdrc"
What is the golden rule I am missing?
- diego
