Razer devices keep reappearing in synapse 3

Are the devices plugged into the hub, or are they plugged directly into your motherboard? Is it still possible for you to test the devices with the Seagate Backup Plus Hub unplugged from the system? I also highly recommend that you perform a clean installation of Synapse by following this guide. If the problem persists, use this to collect Synapse 3 logs. Upload the logs onto a GDrive and send me a shareable link. Edit: *Thread unlocked as per OPs request.

Hi just wanted to share with the community this, in case you might encounter similar type of problem: I was able to solve the problem by installing a PCIe Buffalo USB 3.0 expansion card and connect Seagate drive to that - as the said card supports two USB 3.0 ports, I also attached Firefly to that. I plugged Huntsman elite keyboard directly to the motherboard's backplate USB 3.0 ports, and Tartarus v2 to display's USB 3.0 USB hub (display's USB hub input is connected to motherboard's backplate USB 3.0 port). Naga trinity is also plugged now to motherboard's backplate USB 2.0 port. So I ended up removing the active USB 3.0 hub of https://www.verkkokauppa.com/fi/product/7851/jxqxd/Macally-TRIHUB9-9-porttinen-USB-laturi-hubi and use the USB 3.0 expansion card in motherboard. I also ended up setting HID/USB devices so that the computer can not disable the device to reduce power consumption. Furthermore I reinstalled synapse 3.0. My theory is - based on some googling - that not all powered USB devices like that active USB hub is not allowed to power the connected device.. (I did not test this though, I was happy to get the computer back to usable condition by using the Buffalo's PCIe USB 3.0 expansion board). To recap initial setup was that most of the Razer devices were connected to the Macally USB hub and Seagate was connected to the motherboard's backplate USB 3.0 port. I tried various permutations of how each of those Razor devices were connected to the said HUB, but none seemed to affect on outcome. I also moved Seagate to be connected to the Macally USB 3.0 hub - I also tried to connect Huntsmane Elite keyboard to Seagate's own USB 3.0 hub (while Seagate was still connected to the Macally USB hub), and I also connected said Keyboard (for a test) to Display's own USB 3.0 hub (its input is connected to Motherboard's backplate USB 3.0 connector).
