Many thanks, I've just committed the code with a change in linux_osspec
to check if the device->bus_id starts with i2c instead of checking that
device->bus equals i2c. The latter was 'unknown' on my box - might be a
kernel or libsysfs issue.

I've added that info.[category|capabilities] will be set to i2c. Btw, I
wonder what a desktop application would use such a device for, any
ideas?

Again, many thanks,
David
