    Yeah, I saw the video which is what got me thinking about it in the first place.

    Razer replaced* my V1 Core with a V2, and I can confirm that with a 1st Gen Razer Blade Stealth, my problems have been all but solved. With the V2 unit, I can keep my monitor, GigE, and USB devices attached to the Core, and exclusively use the Thunderbolt connection to the RBS and have everything work as expected.

    The singular problem I have now is that the powered hub I'd purchased, as part of trying to make my V1 Core useful, doesn't work reliably when attached to the V2 Core. Peripherals directly connected to the Core work flawlessly, but anything attached to the hub is still susceptible to the occasional dropout. Hardly a complaint, though, honestly - the dropouts are few and far between compared to anything I'd ever achieved with the V1 (hours vs minutes between issues), and being able to route everything I need for day-to-day use directly via the Core is a truly wonderful experience.

    * The "warehouse" was out of stock, so they issued store credit to purchase one via the Razer Store, which oddly enough, had them in stock. While this meant I had to pay sales tax again, it also meant I got a brand new unit rather than one that was potentially refurbished. I was fundamentally ok with this, and they issued my credit within 24 hours.

    How long did you have the Core V1?

    Almost a year. I was using it (without issue) for awhile before adding a GPU; once the GPU was in, everything went to hell, I opened a case, they wanted an RMA, it came out that it was a V1 hardware/design flaw that an RMA wouldn't be able to rectify, so I sat on it...

    When I learned that the V2 added a second Thunderbolt controller to help mitigate the issue, I asked support if we could re-open the RMA and pursue a resolution, to which they were happy to oblige.

    Nice to hear that, hope all v1 could solve the USB issue like you. I think due GPU price they have a lot v2 stock. Though it’s nice support from Razer.

    So you were able to send in your V1 and get a V2 in return?

    That is correct. When I asked to re-open my earlier RMA, the rep said they couldn't promise a V2 replacement but would pass along the request. I was then contacted by Razer's RMA department, and they basically said "we'd like to replace it, send it in."

    *edit to add: This was all while still under warranty. And, obviously, YMMV...

    I'm extremely curious what exactly they changed about the USB. I do know that in V1, the only logical connection between the PC and the Core is the Thunderbolt channel, and they have a USB controller in the Core hanging off that. It always struck me as an odd choice. Since Thunderbolt 3 is implemented as a USB-C alternate mode, there's nothing preventing them from using the Thunderbolt channel for PCIe graphics, and the USB data channel for the Ethernet and USB ports via a simple hub in the Core.

    Any chance you can look in Device Manager and satisfy my curiosity as to whether that's what they did with V2?

    I never tried the ethernet but it should have better connection (no disconnecting issue) than V1 since they separate a lane on the current gen. TB3 max Bandwidth on current eGPU setting with PCIE3 4lanes is 32gb (each lane is from TB3 device is 8gb and 2 lanes 16gb made performance on internal screen worse since it has less bandwidth to transfer data to device from host but okay if they don’t have to bring it back to device like using external monitor which connects directly to gpu), idk exactly about TB3 max 40GB advertisement maybe it’s for 4K movie data. Pheriperals on Razer Core v2 has 10gb separate bandwidth when I’m not wrong, so as long you don’t use too much data on it like using pheriperals in a dongle while others port is connected to other pheriperals, you’re good. I’m using in 4 USB ports mouse, keyboard, ex HDD, Xbox controller, and i have no disconnecting issues using gtx1080 or 1080ti on the Core.

    I can't read device manager for shit, so here's a screenshot - let me know what you make of it. What I know is that the Core now has two TB3 controllers instead of just one, but from what I'm seeing in Device Manager I can't tell what's interfacing with what. It looks to me like the GPU is hanging off of the first controller, and there's four USB ports and the GigE interface hanging off of the other controller, and it's all encapsulated within TB3 and hanging off of a single TB3 controller on my RBS, but I'm mostly just speculating...

    This actually the reason why ^^^

    No issues with my blade stealth v2 and 780 or 950 with USB devices. Since the core is a USB hub I would recommend plugging peripherals directly into your laptop for reduced input lag, and use the core for extra devices such as backlit mousepads.
