Epson scanner failing to hook up on VBox, any guest.

[Cubytus32]

Hello there,

as a short term plan to upgrade my aging Snow Leopard, I was looking for ways to make my scanner work in a Ubuntu guest on Mac OS X host. It is an Epson Perfection 610 which connects through USB. I know it works in Ubuntu on a real silicon machine. So I shut down a Ubuntu virtual machine, added a USB filter, then restarted it, then plugged in the scanner. Its name appeared, unchecked, in the list of USB devices. I clicked it, then all other peripherals listed disappeared under the "Unknown device" moniker. The scanner was still unchecked. So I tried checking it again, and VBox returned an error. Trying to save the state of the virtual machine failed, and I had to make a hard shutdown.

How would I know why this particular peripheral fails to work correctly? And of course, how to attach it to a VM?

What fields did you enter when you created the filter? Usually the Vendor ID and Product ID are enough to define it (as long as you only have one of that device). Entering the other information usually causes problems when you try to connect.
