#54 Fender Amp USB feed

[Geordon Marchak]

I'd like to bring in a feed from a Fender AMP to linux via ALSA and then on to Audacity. The USB feed itself is recognized OK by the kernel:

/sys/kernel/debug/usb/devices

T: Bus=01 Lev=02 Prnt=02 Port=01 Cnt=01 Dev#= 3 Spd=12 MxCh= 0
D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
P: Vendor=1ed8 ProdID=0031 Rev= 1.00
S: Manufacturer=FMIC
S: Product=Fender USB Audio Streaming
S: SerialNumber=FFFFFFFEFFFF
C: #Ifs= 2 Cfg#= 1 Atr=c0 MxPwr=100mA
I: If#= 0 Alt= 0 #EPs= 0 Cls=01(audio) Sub=01 Prot=00 Driver=(none)
I:* If#= 1 Alt= 0 #EPs= 0 Cls=01(audio) Sub=02 Prot=00 Driver=(none)
I: If#= 1 Alt= 1 #EPs= 1 Cls=01(audio) Sub=02 Prot=00 Driver=(none)
E: Ad=81(I) Atr=05(Isoc) MxPS= 196 Ivl=1ms

But the device doesn't appear in ALSA as a sound card in F6, so it can't be passed on to Audacity for recording. The feed itself works fine on Win10, but I'd prefer to run it on linux. Any way to get this supported?
