Windows 10 Share files EASILY via Thumb Drive

Will above (or similar) allow me to plug a USB3 Thumb drive into one of the sockets, and readily/easily allow connected PCs to share files via the Thumb drive ?
The descriptions (on eBay) don't clarify to me -
- whether all the PCs, that are cat wired to the my router will be able to "EASILY see the Thumb drive"
- PCs plugged into the other two USB3 Sockets, can "EASILY see the Thumb drive"
- If the USB3 cable which is part of the hub, is plugged into a PC, does that "see anything via that cable"
- Can the USB3 cable which is part of the hub, be plugged into a mains converting USB adapter
- Or is their additional benefits to that cable being plugged into one of my PCs

Rob,
PS My PCs are - W10 Pro, W7 Pro, XP Pro

No, it's just a USB hub + extra Ethernet connection.

Thanks for taking the time to respond.
You have saved me some money, and a lot of frustration
