minivox ( mvox100) usb speakerphone doesn't work.

[Sam Kaplan]

The minivox (mvox100) usb speakerphone (http://www.mvox.com/mv100.html) isn't
properly recognised. When the device is plugged in, dmesg reports:

[4296407.944000] usb 5-4.3: new full speed USB device using ehci_hcd and address 6
[4296407.996000] invalid SELECTOR UNIT descriptor 7
[4296407.996000] snd-usb-audio: probe of 5-4.3:1.0 failed with error -5

Does this still occur on the latest Dapper?

Thank you for reporting this bug.

[Sam Kaplan (stkaplan)]

Yes, the problem remains in Dapper, and the error message remains the
same too.

Thank-you very much for your response.

Best,

Sam

Not sure if anyone cares about this anymore but its a really simple fix. Heres a patch for sound/usb/usbmixer.c in 2.6.19.1. You may need to use OSS emulation for some applications to avoid sound distortion.

Thanks for that patch, Tyson.

Is this bug still a problem in Edgy, Sam?

I can confirm this bug on Feisty with an IOGear "usb speakerphone".

Added to my git tree.

I am wondering whether those of you who have this device are using gutsy. If not, could you try gutsy and reply to let us know whether the device works properly?

Thanks.

I have attempted to use it in 7.10 and it doesn't work on a standard install on an intel machine. Would be great if it did work... it is a great little speakerphone.

[Sam Kaplan (stkaplan)]

Hello,

I can confirm that it still does not work in 8.04.

Not a regression - unsetting importance.

[Sam Kaplan (stkaplan)]

The hardware works in Ubuntu 9.10
