I’m attempting to get a USB760 (aka U760, MC760) cellular card working with USB Host. I have the USB modeswitch working, and in fact if I can get this all to work properly I’m going to release some small source snippits that should be able to read the usb_modeswitch.conf file from Linux and modeswitch nearly any device – should be useful for others in the future.
However, the resulting devices don’t appear as any known USB->Serial converters – they all show up as Unknown. An attempt to ignore this and hook up USBH_SerialUSB to it anyway yields an exception on write.
Linux sees the device as a USB Serial just fine using the usbserial module.
