I get an error when trying to play music through USB DACs under Linux. This only happens with a few high end DACs and only when using a NEC uPD72020x chipset USB 3.0 port. The people at RedHat think it may be the NEC uPD72020x chipset is reporting it's capabilities incorrectly. I'm not sure why some only some DACs are effected. it may depend on their chipsets. There is a detailed description of the bug with traces here https://bugzilla.redhat.com/show_bug.cgi?id=1240798 Any idea what I can do to fix this?
Can you re-send the logs. Both dmesg with xhci debugging enabled and lsusb -v. Clicking the links to the logs in redhat bugzilla justs says "The paste you are looking for does not exist" The command completion code 0x11 (17 dec) is a parameter error, indicating that xhci thinks that some value we used in the input context is wrong. -Mathias -- 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
