All versions work well and report the same devices identification of usbdock, but I have a scanner Mustek 1200 USB that when connected is attached and detached in an infinite loop, so, the report is right but sane/tame can't use it. I also disabled the usb widget (eCS 2.2 beta) but the scanner does not work (0kb output), indeed even before (tame included in eCS, the same problem).
Regards.
