USB/ Bluetooth input device support

Hi,

Just wondering if this is likely to drop anytime soon?

Was experimenting with a Retropie install on my HP x360 chromebook .. I've ran this on various Raspberry Pi's over last few years

App itself runs fine on Penguin container - but soon realised that no controller input possible (or certainly not easy) via either USB or bluetooth connection

Found something that maybe could use vmc attach-usb .. found the Bus:Device details from chrome://system under lsusb section but this errors

This is what the syslog says about the attempt:

Bit stumped with it now - any help much appreciated .. understand possibly no workaround at the moment & will have to wait until it gets properly supported in the future.
