Title:
Ubuntu Server image doesn't include common USB drivers / modules
Status in linux-raspi package in Ubuntu:
Invalid
Bug description:
I tried using Ubuntu Server 21.10 (32 Bit) on a Raspberry Pi 3b but
some common USB devices didn't work. On closer inspection the kernel
modules were missing -
Common USB serial adapters: ftdi_sio,pl2303
Common USB modems including 3G Dongles: cdc_acm
I understand the Ubuntu Server image is meant to be lightweight but I
think these devices are common enough to include support for.
Thanks!
