Subject: [PATCH] ALSA: usb-audio: Add sample rate quirk for Microdia JP001 USB Camera
Date: Thu, 15 May 2025 12:21:32 +0200	[thread overview]
Message-ID: <20250515102132.73062-1-kwizart@gmail.com> (raw)

Microdia JP001 does not support reading the sample rate which leads to
many lines of "cannot get freq at ep 0x84".
This patch adds the USB ID to quirks.c and avoids those error messages.

usb 7-4: New USB device found, idVendor=0c45, idProduct=636b, bcdDevice= 1.00
usb 7-4: New USB device strings: Mfr=2, Product=1, SerialNumber=3
usb 7-4: Product: JP001
usb 7-4: Manufacturer: JP001
usb 7-4: SerialNumber: JP001
usb 7-4: 3:1: cannot get freq at ep 0x84
