Device class 0 means "check the interface class" and interface class 255 means "vendor specific". This is an FTDI device which means it uses a vendor-specific USB serial protocol rather than the standard USB CDC-ACM protocol support by this polyfill. Issue #8 tracks adding support for FTDI chips.

turns out the device shows up as class 0, not class 2. not sure what to do with this knowledge because I know nothing about usb-serial. but that's the filter that prevented it from showing. the WebSerial
implementations do handle this somehow. android, mac, windows all return the same info below.

On PC, Mac, Android the device shows up as having only one interface which does not match the device class. So I presumed this could be used as both the transfer and control interface (seems this is anticipated in the code). I changed the serial.ts code to allow searching for devices with a different class code from the class code used later for interfaces. But then USBOutTransfer stalls trying to set line coding.
