ATUALIZADO (veja abaixo)
Depois de instalar o pacote usbip no cliente e no servidor, carregando os módulos do kernel em ambos, iniciei o usbipd no servidor:
sudo usbipd
usbipd: info: starting usbipd (usbip-utils 2.0)EDIT: I found better instructions here: https://github.com/torvalds/linux/tree/master/tools/usb/usbip
cliente: sudo modprobe vhci-hcd sudo usbip attach -r 192.168.5.153 -b 1-1
servidor:
usbipd: info: conexão de 192.168.1.2:40942 usbipd: info: pedido de recebido: 0x8003 (4) usbipd: info: encontrado dispositivo solicitado: 1-1 usbip: info: connect: 1-1 usbipd: info: request 0x8003 (4): completo
cliente:
sudo lsusb (o dispositivo usb esperado não é mostrado e também as ferramentas multimídia do KDE não mostram nenhum novo dispositivo de áudio) usbipd: info: escutando em 0.0.0.0:3240 usbipd: erro: socket: ::: 3240: 97 (Família de endereços não suportada pelo protocolo)
Eu não olhei para o erro acima e não sei se é relevante, mas estou assumindo que não é.
Depois liguei o meu dispositivo usb:
sudo usbip bind -b 1-1
Em seguida, no cliente, anexei o dispositivo:
sudo usbip attach -r 192.168.1.153 -b 1-1
libusbip: error: udev_device_new_from_subsystem_sysname failed
usbip: error: open vhci_driver
As seguintes mensagens foram mostradas no servidor para usbipd (tentei conectar duas vezes):
usbipd: info: connection from 192.168.1.2:40910
usbipd: info: received request: 0x8005(4)

lsusb mostra que o cliente não anexou o dispositivo usb. Os erros relevantes no cliente são:
libusbip: error: udev_device_new_from_subsystem_sysname failed
usbip: error: open vhci_driver
O cliente e o servidor estão executando estas versões:
sudo pacman -Qi usbip Nome: usbip Versão: 4.18-1
Linux 4.18.6-arch1-1-ARCH # 1 SMP PREEMPRE Quarta 5 11:54:09 UTC 2018 x86_64 GNU / Linux
Eu tenho a ajuda da instalação daqui: Tutorial - USB / IP »Revista Linux link
UPDATE: encontrei instruções melhores aqui: link
cliente:
sudo modprobe vhci-hcd
sudo usbip attach -r 192.168.5.153 -b 1-1
servidor:
usbipd: info: connection from 192.168.1.2:40942
usbipd: info: received request: 0x8003(4)
usbipd: info: found requested device: 1-1
usbip: info: connect: 1-1
usbipd: info: request 0x8003(4): complete
cliente:
sudo lsusb
(o dispositivo usb esperado não é mostrado e também as ferramentas multimídia do KDE não mostram nenhum novo dispositivo de áudio)
O diário no cliente mostra que o dispositivo usb está localizado, mas não está vinculado e não está claro para mim o motivo.
