I'm looking for a USB Ethernet adapter with VLAN support. It has to work on Windows 7 Enterprise, and allow me to select which VLAN to connect to. Apparently I'm not able to find one on Amazon or other online stores. Does such an adapter even exist?

This question appears to be off-topic. The users who voted to close gave this specific reason:
I just ordered and received a StarTech.com USB 3.0 to Gigabit Ethernet Adapter NIC with USB Port (http://www.amazon.com/gp/product/B00ECQZM1A/).
It is based on the ASIX AX88179 Gigabit Ethernet Controller.
The listed features include:
As mentioned, it supports VLAN tagging. This is what the related properties of the installed driver (188.8.131.52 / 2014-01-24) look like under Windows 8.1:
HOWEVER: What is missing (at least for me) is any sort of trunking support / virtual miniport driver - such as the additional capabilities provided by the full driver installs of the Intel Advanced Networking Suite (iANS) or Broadcom Advanced Server Program (BASP) .
The difference is, I could configure the switch port to provide access to multiple VLANs, and configure this adapter to choose which VLAN to be a part of - from the client device, not the switch. Or I could add another unmanaged switch with access to the multiple VLANs, then use multiple of these or similar adapters - configuring each one to be on a different VLAN (something like this - yikes!). With proper trunking support, however - everything could be done with one switch port, one wire, and one adapter - very convenient.
As @Flexo noted, I'm sure that the full 802.1q support would be available under Linux with the standard kernel drivers - but Windows doesn't provide these services itself, and depends upon a vendor-provided driver package (e.g. iANS or BASP) to provide them instead. Unfortunately, I'm not aware of any USB Ethernet adapter that provides such a driver package - nor have I seen Intel or Broadcom creating any USB Ethernet adapters of their own that would compare to their internal components.
I have the full capabilities on an aging (Dell Latitude E6500) laptop, compliments of the Intel chipset (82567LM) and driver. I would be very anxious to find a current replacement for this functionality as well - especially for usage with devices like the Microsoft Surface Pro 3. (The Ethernet controller provided on the Surface Pro 3 docking station is no better than the ASIX AX88179 - I checked. It is also internally connected off of the USB, so I guess I shouldn't be too surprised.)
While I hope this answers your question (as written - "allow me to select which VLAN to connect to"), I am still holding out hope that there is still a better solution out there. It just seems like what I / we are looking for here is a bugger to search by - as even "802.1q" and "VLAN" aren't even good enough search terms. (We not only need "tagging", but "trunking".) I plan to offer a bounty here in this regard.
