How to add Touch on USB Host

‎2020-01-20 8:47 PM

I have HID keyboard running on HS and trying to add a touch screen on FS

but when it enumerates the touch screen has a pif->bInterfaceSubClass = 0 , causing a fail in USBH_FindInterface

pif->bInterfaceSubClass is automatically populated by the Touch chip (to 0) during GetDescriptors

not sure which way to go
