Did you have to cut wires or do anything non-standard to use USB hubs with the Allegro Pro card? I haven't been able to get hubs to work with any of the cheaper USB cards I have.

Can't believe I'm going to spend $100 on a USB card, but sometimes 'just works' is worth the premium. Thanks for the update

Since you're not getting any traction I'll throw out an idea. Find a prebuilt vmdk image of XPenology and you'll be able to run it natively in unRaid. Here is a link on how to create a VM with the vmdk. Essentially:

Select the Tools tab > Docker Safe New Permissions. Click the 'Yes I want to do this' checkbox, then start. In almost every case of accessing Docker created files outside a Docker image, that will fix the permission errors.
