Hi,

Thanks for the review.

The bug I was trying to address is that read_port() ignores the return
value from vendor_command() and can return stale cached data after a
failed control transfer.

I updated vendor_command() to use usb_control_msg_recv() based on
review feedback on the previous version.

Would you prefer that I keep the existing usb_control_msg()
implementation and resend a v3 containing only the stale data fix?

Thanks,
Keshav Verma
