HIB Error using Dual TPU, USB works OK (Windows 10)

[mattncsu]

Description

I recently got a dual TPU board and tried running the demo code and I get a HIB error:

C:\Users\Matt\Desktop\smartcam\coral\pycoral>python examples/classify_image.py --model test_data/mobilenet_v2_1.0_224_inat_bird_quant_edgetpu.tflite --labels test_data/inat_bird_labels.txt --input test_data/parrot.jpg
----INFERENCE TIME----
Note: The first inference on Edge TPU is slow because it includes loading the model into Edge TPU memory.
E driver/mmio_driver.cc:254] HIB Error. hib_error_status = 0000000000000010, hib_first_error_status = 0000000000000010
E driver/mmio_driver.cc:254] HIB Error. hib_error_status = 0000000000000010, hib_first_error_status = 0000000000000010

If I disable the cards in device manager and leave only the USB TPU plugged in, the code works as expected. I am running the latest v13 (202110119) since I read in other issues that v14 is not compatible with Window 10. I can see both devices in the device manager and using this script I found in another issue I was reading.

C:\Users\Matt\Desktop\edgetpu_runtime_202110119>python lstpu.py
0 USB /sys/bus/usb/devices/4-4
1 PCI \?\ApexDevice0
2 PCI \?\ApexDevice1

Aside from ditching Windows (working on setting up dual boot), any advice for resolving the HIB error?

Edit: Setup dual boot with Ubuntu and test case works as expected there using dual tpu. Confirms it could be a Windows only problem.

Glad to know it's working with Ubuntu. Can you please share your hardware details that would help others to know this hardware works with dual edge tpu.

Thanks

@hjonnala I'm using a pre-production adapter board made by @magic-blue-smoke (based on a PCIe switch) and an m.2 NVME to PCIe adapter board, photos and more info in this issue:magic-blue-smoke/Dual-Edge-TPU-Adapter#3 (comment)

Got the exact same error when running on Linux on x86-64. Restarting the device didn't help but powering it off and on again (physically disabling the power supply) and then restarting it fixed the error.
