As i understand, device will not be disconnected in case of just not compliant to anything. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1983998 Title: USB sound card not detected Status in alsa-driver package in Ubuntu: Invalid Bug description: usbc mics https://www.boya-mic.com/lavaliermicrophones/1430.html connects and immediately disconnects, ls usb hangs for a while, when usbc device is connected. it works on win laptop well. ``` [10877.622942] usb 3-4: new full-speed USB device number 28 using xhci_hcd [10877.779590] usb 3-4: New USB device found, idVendor=0c76, idProduct=153f, bcdDevice= 1.00 [10877.779596] usb 3-4: New USB device strings: Mfr=0, Product=1, SerialNumber=0 [10877.779599] usb 3-4: Product: USB PnP Audio Device [10877.983589] usb 3-4: Warning!
