Hi
More information about the case as asked.
My kernel version is 2.4.25
My port mean what is says in dmesg when i plug my device. ( So yes there
is two physical connectors and one virtual connector in my hub ( to down
stream ). Here is what dmesg is saying from it. ( i have but some debug
in
usb.c: kmalloc IF da71a8c0, numif 1
usb.c: new device strings: Mfr=0, Product=0, SerialNumber=0
hub.c: USB hub found
hub.c: 3 ports detected
hub.c: part of a compound device
hub.c: ganged power switching
hub.c: global over-current protection
hub.c: Port indicators are not supported
hub.c: power on to power good time: 44ms
hub.c: hub controller current requirement: 100mA
hub.c: port removable status: FFF
hub.c: local power source is good
hub.c: no over-current condition exists
hub.c: enabling power on all ports
usb.c: hub driver claimed interface da71a8c0

bInterval = ff
hub.c: port 1, portstatus 100, change 0, 12 Mb/s
hub.c: port 2, portstatus 103, change 0, 12 Mb/s
And here is how the device is showing in
/proc/bus/usb/devices

And here are information which is missing or i don't know where to look
for them.

};
So here is little more information. I am still learning usb so here
could be some irrelevant data but i hope that these information helps.
So what i meaned that virtual port was that interfece 0. But somewhere
in these descriptors are some errors. But i cannot find them i hope that
some one can help me.
And some tips how can i get hold that interface0 would be nice.
Yours
Kari
