Can you build and test a kernel which includes the patch below and see if
this makes your device work?
It seems our driver is a bit too conservative about matching devices with
product ID a0f0. We filter AX201 devices by subsystem ID, but looking again
at what the Linux driver does, a0f0 products with any subsystem ID should
work.
