Hi Marcel,

thank you for your tip.

I tried loading hci_usb with option isoc=3D0, but still nothing happens.
I don't think if this is question for USB Guys, because other devices eg.
printer, mouse, keyboard, flash-disk etc. works fine and all together
attached into one USB HUB.
I think this is problem with any component from bluez stack...

BR
Petr
