Hi, When I connect my new USB speaker, dmesg is flooded with the following message repeated over and over, and the speaker is not reconized as a sound device: [ 317.492017] xhci_hcd 0000:00:14.0: Trying to add endpoint 0x2 without dropping it. [ 317.492019] usb 3-8: Not enough bandwidth for altsetting 1 [ 317.492020] usb 3-8: 2:1: usb_set_interface failed (-22) It seems the problem was already reported, as I found this thread when searching for the device id e3b4:0811: https://www.spinics.net/lists/linux-usb/msg128181.html $ uname -a Linux quarto 4.15.0-15-generic #16-Ubuntu SMP Wed Apr 4 13:58:14 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux I once managed to get the speaker to work by disabling XHCI, but I forgot how I did it (and I assume it is best to fix xhci_hcd). Can someone help me solve the problem? -- Lucas Clemente Vella lvella@xxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
