But earlier in boot these messages are seen:
[ 1.908489] usb 1-1: New USB device found, idVendor=054c, idProduct=0ca1, bcdDevice= 1.00
[ 1.908503] usb 1-1: New USB device strings: Mfr=2, Product=3, SerialNumber=4
[ 1.908508] usb 1-1: Product: WALKMAN
[ 1.908513] usb 1-1: Manufacturer: Sony
[ 1.908516] usb 1-1: SerialNumber: 10458B55477916
[ 2.195821] usb-storage 1-1:1.0: USB Mass Storage device detected
[ 2.195988] scsi host0: usb-storage 1-1:1.0
ProductId is different, that's strange.
Neil, could you collect the dmesg from the working kernel 5.10 please?
And: is the device expected to be a mass storage (aka USB disk) and sound card in one?
Thanks,
Carsten
