How to connect USB device

English Hardware
1

Hi All,
I have a device connected to USB (A guitar pedal board, Mooer GE200) that allows, among other things, new amp sims to be installed from a computer. I’ve plugged it into a USB port and lsusb shows it is there as STMicroelectronics GE200), but I can’t figure out where (or if) its’ mounted.

The software is unfortunately Window$ only (or Mac) but it seems happy to run under wine, except that it cannot detect the device even though it’s plugged in. So I guess the issue could be wine related too.

I’ve searched for similar issues and found that the device is on /dev/snd/controlC2. I’ve tried mounting that to /mnt but the software doesn’t find it. I’ve tried using winecfg to allocate /dev/snd/controlC2 to drive D:, but that didn’t work either.

I’m stumbling around in the dark here as I really don’t know much about how this stuff all works. All advice gratefully received.

:frowning:

Also run

usb-devices

to check if it is recognized by the kernel with a driver loaded for it.

As it is an audio device, the notion mounting is irrelevant (as not a storage device). You may need to use wireplumber to investigate further.

In a Linux termnial do

wpctl status

and report back.

You might need to set it as the default device before running the windows software (via wine).

Further to the above, run winecfg > Audio tab, and see if you can set the appropriate audio device there.

Thanks for the quick replu @deano_ferrari . Here’s the output from usb-devices, or the bit that relates to the Mooer anyway.

One other thing I discovered by accident, is that I can select the Mooer as an output audio device in the audio settings, and audio magically comes out of my guitar amp. So It seems linux doesn’t have a problem recognising it. It must be something to do with wine? I’ve read there are all sorts of problems getting wine to talk to a usb device, and other posts that say it’s easy. Just add a disk drive (i.e. D:) and point it to the device using winecfg. Problem is, /dev/snd/controlC2 doesn’t appear in the list of drives that can be allocated to a drive in winecfg. And mounting it on a drive that IS in the list, i.e. /mnt, doesn’t seem to work either. Another post suggested making a symlink to a com port in ~/.wine/dosdevices/com34. Tried that, still the s/w can’t find it. Maybe I should go and try something easy, like brain surgery. :-\

Yep, as you can see handled by the snd-usb-audio driver. It also acts as an input device (the pedal?) handled by the usbhid driver.

See my earlier reply about configuring audio via winecfg.

You could run the following in a terminal

dmesg -w

then plug the device in, and capture the output. That might provide more detailed information including the input device. Not sure what might be needed from a wine perspective though.

FWIW, here’s a wine page regarding HID devices…
https://wiki.winehq.org/Hid

Late here, I’ll check back on this tomorrow.

Here’s the output in dmesg.

Thanks.

Well, I think I’ve proved that it’s a wine problem. I have another window$ app, that I haven’t used for ages, that also talks to a usb device (this time a programmable touch screen device), and it couldn’t find the device either. Linux could find it and connected it to /dev/ttyUSB0, which is correct. And a linux app I have that talks to usb devices recognised it. So it’s looking like wine is the culprit. I’ll have to do some more digging into that.

:-\

Yes, somehow you need to get the HID input device (/dev/hidraw2 ?) available to wine somehow. Not sure if this is just treated as a character device linked to a com port, or more complex than that.

FWIW, I’m going to share this with you (re wine HID support)
https://www.winehq.org/pipermail/wine-devel/2016-November/115142.html

This may be of interest to you with respect to setting r/w access to the appropriate group. The user running wine would then need to be a member of this group eg ‘lp’ group.

YMMV
