Hi @Vignesh_Raja
We just ordered a Coral, @numbqq and @Frank will try to fix this issue once the package is delivered.

Good day!

Is there any solution to this problem?

@brunovollmer @David_Zou @Vignesh_Raja Mainline kernel can use coral now. 4.9 kernel still haven’t run it.

@Frank I have used the Google USB Coral with the latest Ubuntu Image and all the code samples from Google Coral works within a matter of minutes. Thanks for it.

Good to hear that. Will test it on Monday with the mainline kernel!

I made a statement inside, how to use
