Subject: Which node has the device been bound to?
Date: Wed, 29 May 2002 10:23:34 +0000 [thread overview]
Message-ID: <marc-linux-hotplug-102266789207618@msgid-missing> (raw)
Within a USB policy agent script, can we tell precisely which node the
device has been bound to? According to
Documentation/usb/usb-serial.txt:
When the device is connected and recognized by the driver, the driver
will print to the system log, which node(s) the device has been bound
to.
But the log message is too succint:
May 27 10:51:11 localhost kernel: usbserial.c: Compaq iPAQ converter
now attached to ttyUSB0 (or usb/tts/0 for devfs)
In case of one iPAQ, we can find the relevant log entry by grepping the
LAST matched line. But if two iPAQs are attached nearly at the same
time, the last matched line may not be the relevant entry because
context switching may happen between two agent scripts.
Do you have any method that can solve it?
Thanks.
