Description Iwan Gabovitch 2016-01-12 20:25:46 UTC

Hello,

When I use my Zoom H2n as an audio interface, it shows up in dmesg as:

> [ 1125.666708] scsi 5:0:0:0: Direct-Access     ZOOM     H2n SD R&W       0.01 PQ: 0 ANSI: 2


However in pavucontrol, it shows as

> H4 Digital Recorder

It would make more sense if it showed up as
"H2n Digital Recorder" or
"Zoom H2n Handy Recorder" since that is it's official name or just
"Zoom H2n"

This might be a problematic issue in the rare case of somebody having both a H4 and H2n connected.

pulseaudio 7.1
pavucontrol 3.0-3

This likely comes from the USB ID database:

1686  ZOOM Corporation
	0045  H4 Digital Recorder

...assuming "lsusb" shows a line with "ID 1686:0045" that points to your recorder.

I believe you can submit a patch to the usb ID database to change it to, e g, "H2n/H4 Digital Recorder" instead. The USB ID database is here: http://www.linux-usb.org/usb-ids.html

Please reopen the bug in case my guess is incorrect.

Oh, here's some interesting info:

When I connect a Zoom H6 recorder, I can choose between "Stereo Mix" and "Multitrack". If I select "Multitrack", it shows up as ID 1686:01c5, but if I select "Stereo Mix", it shows up as ID 1686:0045, like yours do as well.

Hence, perhaps the USB ID string should be "H-series digital recorder" instead. What do you think?

Thanks for replying.

This is strange.

Zoom H2n only has one USB audio mode.

What does dmesg show for the Zoom H6 modes?

I'll write to the usb id repository and see what they say about this then.

PS: I just want to correct this:
>When I use my Zoom H2n as an audio interface, it shows up in dmesg as:

This shows up when I connect it in card reader mode!

When I connect it in audio interface mode, I only see in dmesg:
[13486.890013] usb 3-2: new full-speed USB device number 6 using ohci-pci
