Public bug reported: 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.
