Miniature USB 3.0 hub?

[flyingfishfinger]

Heyo-
Figured I'd try asking here, maybe someone has a lead. I'm looking for the smallest possible 2-port USB 3.0 hub to fit inside my X210 (see my blog post here, under SD Card).

I was planning to use the Nanohub from Muxtronics on Tindie, but it's been unavailable for a year and attempts at contacting the author have been unsuccessful.

I've also seen this thing on Wish, but it's also out of stock...

Does anyone have other suggestions for USB 3.0 hubs of similar size? I've run out of ideas..

Cheers,
R
