Hi Fons,
possibly the USB hardware in the two laptops is different. Since lsusb
picks the device up the next step would maybe to check if udev is
creating the right device nodes.
Try running
sudo udevadm monitor
on both devices and see if there are significant differences..
Kind regards,
FPS

Hello all,
A friend of mine, who is mainly a Windows user and has limited knowledge of
Linux, has two HP laptops running Archlinux.
One of them works perfectly with an RME Octamic-XTC. The other doesn't
seem to detect it as a sound card (it doesn't show up in aplay -l).
On both the RME is recognised as an USB device (by lsusb).
I'm trying to help him fix this (remotely). We compared kernel and alsa
versions, they are the same. In fact the two Linux installations should
be identical, both had a full update before I shipped to two laptops
to him.
What could be the problem on the second PC ?
TIA,
