nayasisMy good friend, your fix has not worked for me at this stage...
My host is Windows 10 Pro 64bit
My guest Windows XP Pro SP3 32bit
My VBox version 5.0.16 with extension pack installed.
I have the now well documented problem of not being able to attach USB devices : 2 printers and a film scanner ; one printer (Brother HL-2040) and the scanner are machines older than USB 3.0, the other printer (Epson SC P600) is a current model and does not pose a real problem since I can use it from the host system. For the film scanner the issue is serious since only Windows XP can support it.
I have tried your fix, in which the registry step was not needed since the UpperFilters entry does not exist for me. No success.
In the VM, the USB controller is set on USB 2.0 (Windows XP does not support 3.0) ; my brand new Shuttle desktop has only one USB 2.0 terminal, so I have reconnected my Brother printer to this terminal for testing : no success.
VM Manager shows one filter for the Brother printer, but the drop-down list from the guest "devices" tab in the status bar shows Brother HL-2040 two times.., both of them giving me the same error message that you know well.
Have you any suggestions, has anybody a similar experience ?
Many thanks to
nayasis and all the people here who are trying to compensate for Oracle's slow response to the problem.
