O valor bcdDevice para os hubs raiz USB na saída do pastebin indica que sua versão do kernel é 4.17. *.

A última linha na saída pastebin indica que um Dispositivo de Billboard USB está sendo detectado.

Se eu entendi corretamente, isso indica que o dispositivo tem um ou mais Modos Alternativos de Tipo-C USB (provavelmente DisplayPort ou mesmo Thunderbolt) e o sistema não conseguiu ativá-los.

Deve haver um Gerenciador de Portas Tipo-C USB no seu kernel: é um dos novos recursos da versão 4.17 do kernel. Pelo menos antes da versão 4.17 do kernel, costumava haver módulos do kernel chamados typec , typec_ucsi e ucsi_acpi , possivelmente com outros módulos ucsi_<something> para Macs e / ou outro hardware não-PC. Eu realmente não sei como o gerenciamento de portas do Tipo-C deve funcionar nos kernels 4.17 e acima, mas se esses módulos existem em sua versão do kernel, você provavelmente deve tentar carregá-los.

O suporte a USB Type-C está em andamento, e acho que a próxima versão principal (4.18) inclui mais alguns pedaços de suporte a Type-C.

Se o conversor for essencialmente um conversor DisplayPort-para-VGA, ele poderá aparecer como uma das saídas listadas pelo comando xrandr quando o Modo Alternado DisplayPort for ativado com sucesso. Mas se é um verdadeiro dispositivo Thunderbolt, seria basicamente um GPU extra para o seu sistema: ele apareceria em lspci como uma placa gráfica extra.

Este documento descreve como o controle do modo Tipo-C deve trabalhos.

Essencialmente, parece que você deve encontrar um arquivo chamado /sys/class/typec/port<number>/<alternate mode>/mode<number>/active que corresponda ao seu adaptador, e então faça algo assim acontecer (de preferência, automaticamente quando o dispositivo for detectado):

echo 1 > /sys/class/typec/port<number>/<alternate mode>/mode<number>/active

Se o diretório /sys/class/typec estiver vazio, você definitivamente não terá todas as peças para suporte a USB Type-C ainda em execução. E isso é um pré-requisito para o Thunderbolt 3.
