Old patch that would probably solve this issue (954 bytes, application/mbox)

Old patch that would probably solve this issue


I experience an annoying chipmunk voice when trying to record with the USB mic in the webcam Logitech C270. It does not happen always but randomly.

According to the 2011 old thread on the Archlinux forum this issue was solved by the patch attached in this bug report. However if I look at the source of the kernel I do not see the relevant line for the webcam which is 046d:0825.

Would it be possible to include this patch in the kernel in order to solve this very annoying issue?

All USB bugs should be sent to the linux-usb@vger.kernel.org mailing
list, and not entered into bugzilla.  Please bring this issue up there,
if it is still a problem in the latest kernel release.

I think this is a duplicate of Bug 44281.
Comment 3 tbertels+bugzilla 2024-04-28 12:56:50 UTC
Is this still a problem with recent kernels?

drivers/usb/core/quirks.c now does contain

/* Logitech HD Webcam C270 */
{ USB_DEVICE(0x046d, 0x0825), .driver_info = USB_QUIRK_RESET_RESUME },

How recent?  I believe I've seen the bug with 6.4.12.
