What is it?

Want to use a Logitech Unifying Dongle (or similar) without having a dongle permanently sticking out and giving up on a precious expansion card slot?

Now there's the DongleHider+!

Simply (permanently) mount the dongle inside the card and still have an USB A port available!

There even is room and solder pads for 1-2 additional dongles. Your imagination (and physics) are the only limits!

Compatibility Notes

The expansion card was only tested on Windows and AMD Framework 13 and 16 laptops as of right now. There the following behaviour has been observed:

With only a dongle active, the CH334 hub IC draws around 20mA. (In addition to the ~25mA of the Unifying dongle) When nothing is connected to the hub, it goes to sleep and draws <1mA. (But this is seldomly the case with a dongle permanently attached to it :P ) Despite earlier fears, the USB 3 "route-around-2.0-hub" topology doesn't seem to cause problems in the wild, except: When connected to a USB4 capable expansion card slot and an external USB 3 device is plugged in, the internal dongle stops working, but is still displayed as connected in Windows. As soon as the USB 3 device gets unplugged, the internal dongle immediately begins to work again (probably without a re-enumeration). USB 2 devices seem to work without a problem for the most part, although one of the tested USB thumb drives took a few re-plugs until it enumerated. This behaviour is not seen on the other non-USB4-capable expansion card slots, there USB 3 devices work great alongside the internal dongle

It can either come woth a Logitech adapter installed or a samsung USB flasb storage device. All additional addons are new.
