Lenovo ThinkStation P620 is like other TRX40 boards, is equipped with two USB audio cards.
USB device (17aa:104d) provides functionality for Internal Speaker and Front Headset. It's UAC v2, so it supports insertion control (jack detection). However, when trying to get the connector status of the speaker, an error occurs: [ 5.787405] usb 3-1: cannot get connectors status: req = 0x81, wValue = 0x200, wIndex = 0x1000, type = 0
Since the insertion control works perfectly for the headset, the error for speaker is probably casued by connecting internally. So let's relax the error for a bit if it's a speaker, and always reports it's connected.
USB device (17aa:1046) is for rear Line-in, Line-out and Microphone. The insertion control works for all three jacks. However, there's an Function Unit that doesn't work: [ 5.905415] usb 3-6: cannot get ctl value: req = 0x83, wValue = 0xc00, wIndex = 0x1300, type = 4 [ 5.905418] usb 3-6: 19:0: cannot get min/max values for control 12 (id 19)
So turn off the FU to avoid the error.
Also, add specific card name for both devices, so userspace can easily indentify both cards.
