To me it seems that any solution reliable in what does / doesn't work that uses cheap & commercially available products is good enough (no hardware hacking allowed.) To me it seems that the minimum requirement is that one device works reliably. Every device working reliably doesn't seem like a requirement, but the testing of each device should be documented. For example if USB 1.1 devices don't work then avoid USB 1.1 devices.

Any love for meego yet? It is much newer.
