Hi there:
I'm doing a new install of gentoo on a PC desktop that has a USB devices:
| Code: | # lsusb
Bus 001 Device 003: ID 18ec:3399 Arkmicro Technologies Inc.
Bus 001 Device 002: ID 090c:6300 Silicon Motion, Inc. - Taiwan (formerly Feiya Technology Corp.)
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub |
The problem is that this error with pulseaudio (all in red colour) and sometimes I have to reconnect the webcam:
| Code: | journalctl -b | grep pulseaudio
