Issues with different room PC setup when using USB3.0 devices

Hi,

I recently purchased a fiber optic setup to connect my PC to my TV on the other side of the apartment, and I am having problems with it. The Display part of the solution works perfectly fine, i can transmit 4k@120 with HDR, Dolby Vision & Atmos and G-Sync enabled without problem. Unfortunately i cannot get the USB solution to work for my usecase (connecting a USB Keyboard, Mouse and Controller), which i would have honestly expected to be the easier part…

The fiber USB Adapter just refuses to send data for any device that is not acting in pure USB 3.0 mode (even through the USB Hub), which means that an external Samsung SSD works perfectly fine at max USB3.0 speed, while not a single mouse, keyboard or controller i own is even detected at all by my PC. I have already been in contact with heyoptics.net and they have issued a refund for the adapter, which is good customer service but doesn’t get me closer to solving my usecase (they said that USB2.0 device support is spotty).
I have also tried using an old Raspberry Pi 3 ModelB v.2 i still had lying around to connect my devices using the linux native USBIP solution + GitHub - vadimgrn/usbip-win2: USB/IP Client for Windows on my PC, which I couldn’t get to work either. I have opened an issue on their github project as well, if anyone would like to read up on it, though I haven’t yet taken the time to dig deeper.
The last thing I have tried is a trial version of USB over Ethernet: share USB port over Network (LAN and Internet), which also does not seem to work (though it at least doesnt crash the raspi). I got as far as connecting the keyboard+mouse through the usb network gate client, though I am unable to actually control anything on my PC using them.

My question now is quite solution oriented: Is there any known working solution to my usecase that works without any additional cables (the TV room is wired for ethernet already) or expensive additional devices? Ideally, I would search for some software/driver level solution to somehow encapsulate the USB2.0 traffic my input devices are generating into a virtual USB3.0 device so that I can use the fiber adapter already in place, though I am not knowledgable enough to know if that is possible. Another solution I imagine could work is using input devices which are natively USB3.0, though I can’t imagine there are any, since it just doesn’t make any economical sense.

My setup:

PC → HDMI to MPO OM3 Fiber Adapter (Source) + USB to MPO OM3 Fiber Adapter-> MPO OM3 2x6 to 1x12 Splitter → Fiber Cable through the apartment → MPO OM3 2x6 to 1x12 Splitter → HDMI to MPO OM3 Fiber Adapter (Display) + USB to MPO OM3 Fiber Adapter → TV + Powered USB 3.0 Hub.

These are the products used:

https://www.heyoptics.net/products/optical-usb-cable

TLDR: Need a solution to connect 3x USB2.0 devices to a PC in another room without pulling additional cables.

Thanks to anyone kind enough to read through all that, appreciate any help.

In the enterprise world there are some USB switches tbag connect to remote machines a d transmit over fibre… But they are very niche and very expensive for ehat they are. They are commoning used in commercial flight trainers sims.

Yeah that’s the big gotcha with USB extenders, unless it explicitly says so, they have compatibility problems.

Do you have Ethernet run to both locations? If so, then I’d suggest looking at extron’s usb extenders plus series, which you can find $50-70 on eBay. Be aware many listings don’t seem to include power supplies.

These are USB 2.0/1.0, and do not require their own dedicated cable. You just attach them to your network and it’s like two network devices that just connect to each other. Mine work even going through 2 switches and Coax/MoCA adapters. You can even attach a USB hub to them. It all just works beautifully.

You’ll need a transmitter box, a receiver box, and the power supplies for each, which have a somewhat unusual captive screw fitting

Don’t confuse with Extron’s non-plus series extenders which are not compatible with the plus series because I believe the non-plus series require being alone on their own dedicated Ethernet cables.

That looks pretty promising. Do you think extending my current setup (blue) with those extenders (green) would work even through 3 switches while preserving the normal local network? Or do those extenders need their own seperate network / VLAN?

The plus series play nicely alongside everything else attached to a network, no need for isolation unlike other adapters.

Basically if you could attach computers/network devices on either side of the network and have them talk to each other, then these will work just the same. The transmitter and receiver are usually already “paired” when bought used, at which point they find each other automatically when powered on. If they need to be paired, it’s easy enough to do, just see the info pdf in the previous post.

If vlans are involved, then whether they can see each other will depend on how you’ve set things up, just like other network adapters.

I suppose one caveat to consider is if you are doing something that requires the full USB 2.0 480 megabit bandwidth, this is a considerable portion of a 1 gigabit Ethernet connection. This would only happen (temporarily) if you plug in a USB drive and transfer things though. The bandwidth used by mice/keyboards is tiny, though I’ve never explicitly measured it. Basically not an issue unless you have something that needs over half your connection constantly.

Great display success! Now to find a USB solution that works!

@Log Thanks for the name drop. I forgot to mention the name in my post. Getting old. Haha. Now what was I doing?!
