Usb Gurus,
I am working on a biometric device (fingerprint reader) for Linux. This
device has 2 configs and I need to use the 2nd config. On initial connect
to the system usb core selects config #1 and my driver claims the interface.
I can
cat bConfigurationValue
and see the response of '1' properly.
But, I then do the
echo '2' >/sys/bus/usb/devices/2-2/bConfigurationValue
and when I read the bConfigurationValue it is null. It is not 0 or 1 or 2.
And my driver is unbound and probe is not called again. Like the device
is no longer present.
I am running 2.6.9.
Any clues what is happening ? Any ideas on how I can select config #2.
Thanks in advance,
Mike
