Windows 11 USB Accelerator USB error -99 [OpenDevice]
Description
Hi,
I'm encountering issues with the Coral Edge TPU USB 3.0 Accelerator on Windows 11, specifically related to poor performance and stability. In this case I am using EfficientDet-Lite0 (int8) along with pycoral version 2.0.0.
When using the edgetpu_runtime_20221024 performance driver (latest), the accelerator has a throughput of 30fps but after exiting the inference loop, running the program for the second time pycoral fails to use the accelerator until a system restart or a port change.
Using the edgetpu_runtime_20210119 performance driver, the accelerator performance drops to 15fps, but the usb seems to be released every time, so the script can be run as many times as needed.
