I found a tool [1] written for a device by the same vendor, so likely to
share hardware/firmware and it sends a single packet to make the device
work.
It sort of works for me, except I have to unplug and re-plug the device
to make it work.
My question now is, is there a quirks flag and configuration that allows
me to do the same thing on plug-in?

I have this USB device called TC-Helicon Blender which provides 12

If I power the device on while connected to a windows machine with its
driver installed, then plug it into my linux machine, it appears to
work correctly:
arecord -D front:CARD=Blender -r48000 -fS32_LE -c 12 blender.wav -d 20
Recording WAVE 'blender.wav' : Signed 32 bit Little Endian, Rate 48000
Hz, Channels 12
46080044 blender.wav
However if I have it on my linux machine while powering it on, I only
get timeouts and no samples from arecord:
arecord -D front:CARD=Blender -r48000 -fS32_LE -c 12 blender.wav -d 20
Recording WAVE 'blender.wav' : Signed 32 bit Little Endian, Rate 48000
Hz, Channels 12
arecord: pcm_read:2221: read error: Input/output error
44 blender.wav
What can I do to try and get this device to init correctly under
linux? I have captured USB packets of the init phase using wireshark
on both windows and linux but comparing them is tedious if I don't
know what to look for. Are there quirks flags I can play around with?
This is my first time looking at a linux device driver issue like this.
Would it be ok to attach the usb captures on this mailing list?
thanks
