I also followed sandy’s bit of advice here and had a look. I couldn’t figure out which usb socket was the microphone.
bus 001 device 006: ID Obda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter
bus 001 device 005: ID Oa12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
bus 001 device 004: ID 8086:0808 Intel Corp.
bus 001 device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
bus 001 device 002: ID 0424:9514 Standard Microsystems Corp.
bus 001 device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
So far I’ve figured out the obvious ones, 006 is wifi, 005 is bluetooth, 003 is the ethernet, 002 is the empty usb port.
However I don’t know which one would allude to the microphone from pimoroni…
Actually, I figured it out, it was the Intel Corp. one, I did this by taking usb out and checking the usb list then finding the missing one.
I’ll test out the rest and hopefully anyone trying to do the same as me, can see this post and be helped.
