Hey everyone, I just made the jump from a 6600 to a 9070xt GPU in my setup, and since then, my PCIe Bluetooth chip has been acting up. I bought the Bluetooth card not too long ago in December, and it worked perfectly until I upgraded my GPU. Now, things get really buggy.
When I first boot up my PC, the Bluetooth functions normally, connecting to my peripherals without issue. But once I start playing any heavy games like Borderlands 4 or Ratchet and Clank: Rift Apart, it lags and eventually stops responding entirely. My devices show as connected, but they just won't work.
I've been getting error code 43 with the message that Windows can't detect the device but lately, it's just showing up as an unknown USB device instead. The only fix so far is to restart my computer, but the Bluetooth goes out as soon as I try to launch any graphically intense game. Interestingly, the WiFi function on the same chip is totally fine, and Bluetooth dongles work without a hitch.
Here's what I've tried so far:
- Swapped the PCIe slot
- Reseated the Bluetooth card
- Updated all my drivers (Windows 11, BIOS, chipset, GPU)
- Made sure the BIOS recognizes the PCIe lane
Despite trying a bunch of things, I'm still stuck. It's frustrating not being able to use it since it's only the Bluetooth functionality that's failing. Any insights would be appreciated! Here's my setup:
- 9070xt GPU
- 5600g CPU
- MSI MAG A850GL PSU
- MPG B550 Gaming Plus Motherboard
- Ax3000 Trendnet Bluetooth/WiFi card

It sounds like your Bluetooth card might not be dead but rather facing a PCIe lane conflict due to the new GPU. Since the WiFi part is still functioning well, that’s a good sign. I suggest checking your motherboard’s manual to find a PCIe slot that doesn’t share lanes with the GPU. If that doesn’t help and you have a USB Bluetooth dongle that works fine, that might just confirm the slot’s the issue. You could either switch to that dongle or consider using a riser card. Sometimes the GPU can hog resources, especially when under load.
I moved the card from the PCIE_E3 (3.0 x4) to the PCIE_E4 (3.0 x1), but it didn't solve the issue. My GPU is taking up the PCIE_E1 (4.0/3.0 x16) slot and it’s blocking access to the PCIE_E2 (3.0 x1). It’s frustrating!
