Hi,
usb_id etc is ok, but I found that the properties are not written to the udev database. After some research (actually more try&error) I found the reason is, that there is no NAME for the hso0 device. I added a line
KERNEL=="hso0", NAME="hso0"
And now it works :-)
Question is, is there any udev rule file that is missing on my system that is supposed to do that job or could it be a missing kernel option?
I saw a similar behavior for Ericsson MBM device (unfortunately I don't have one here to test), so it seems to be a general issue on that system.
Thanks very much for your support, this was a long standing issue on that system and I am very happy to found the reason!
Regards
Gerald
