Comment 139 for bug 843431

I'll check that but if you look at
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/tree/drivers/usb/core/quirks.c?h=v4.15.18
you can see that devices listed in #37 are not there and for me :
/* Logitech Quickcam Pro 9000 */
{ USB_DEVICE(0x046d, 0x0990), .driver_info = USB_QUIRK_RESET_RESUME },
is not there !!!
but
{ USB_VENDOR_AND_INTERFACE_INFO(0x046d, USB_CLASS_VIDEO, 1, 0), .driver_info = USB_QUIRK_RESET_RESUME },

is!!
as additional information :
- Skype is working well but arecord no, audacity neither.
- It was working fine under ubuntu 16.04 but not 18.04
I'll will go into further investigation next weekend...
