Hallo zusammen,

ich würde gerne den USB Google Coral nutzen auf meinem Archlinux System auf dem T450 Lenovo.

Nach Einstecken wird dieser aber nicht vom System erkannt. Ich habe bereits alle physischen USB Ports ausprobiert. Was mache ich falsch?

➜ ~ uname -a
Linux T450 6.1.1-arch1-1 #1 SMP PREEMPT_DYNAMIC Wed, 21 Dec 2022 22:27:55 +0000 x86_64 GNU/Linux

danke für deine Antwort! Das habe ich wie folgt erfolgreich gemacht:

yay -S python-pycoral libedgetpu-std

`➜ pycoral git🙁master) ✗ yay -Ss pycoral
aur/python-pycoral 2.0.0-3 (+0 0.00) (Installed)
Google Coral Python API

aur/libedgetpu-std 16.0-1 (+4 0.04) (Installed)
Google Coral Edge TPU library and headers (standard speed).`

Der USB wird aber trotzdem nicht richtig gemountet, siehe hierzu Folgendes:
`➜ pycoral git🙁master) ls -l /dev/serial/by-id

total 0

Google Coral USB ist als folgendes Gerät erkannt aber nicht gemountet als device:

Debugging with udevadm
`➜ pycoral git🙁master) udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent
