There are USB-to-LAN-cable extenders that use a LAN cable for longer stretches. Some of them are comparatively cheap, but the fine print usually shows them up as "full speed", namely 12Mbps, making them unsuitable for most soundcards but not for MIDI. But when hubs (built-in?) come into play with other slow devices, the potential for "hub problems" grows again by leaps and bounds. -- David Kastrup _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
