I too applied your patch and configured my UAC2 gadget with the
following pertinent parameters:
mkdir -p "/sys/kernel/config/usb_gadget/g_multi/functions/uac2.usb0"
echo "${req_number:-4}" >
"/sys/kernel/config/usb_gadget/g_multi/functions/uac2.usb0/req_number"
echo "${c_ssize:-4}" >
"/sys/kernel/config/usb_gadget/g_multi/functions/uac2.usb0/c_ssize"
echo "${c_srate:-48000}" >
"/sys/kernel/config/usb_gadget/g_multi/functions/uac2.usb0/c_srate"
echo "${c_chmask:-0xFFFFFFFF}" >
"/sys/kernel/config/usb_gadget/g_multi/functions/uac2.usb0/c_chmask"
echo "${c_sync:-adaptive}" >

echo "${p_ssize:-4}" >
"/sys/kernel/config/usb_gadget/g_multi/functions/uac2.usb0/p_ssize"
echo "${p_srate:-48000}" >
"/sys/kernel/config/usb_gadget/g_multi/functions/uac2.usb0/p_srate"
echo "${p_chmask:-0xFFFFFFFF}" >
"/sys/kernel/config/usb_gadget/g_multi/functions/uac2.usb0/p_chmask"
Unfortunately, under Windows 10 I get the following error loading the driver:
This device cannot start. ( Problem Code 10)
Problem Status: C0440022
So the generic Windows (Thesycon) UAC2 driver appears to fail loading
the Linux UAC2 gadget device. Can you share with us your configuration
or how you tested this with Windows 10? I tested audio capture with
another Linux PC running Audacity and it was correctly detected and
seemed to work. I'm hoping it's a simple misconfiguration issue. Can
you offer suggestions?
Thanks,
Glenn
