I'm pretty sure this isn't the right list, since the following is only tangentially related to Gadgets et al. If you know the right list (I don't), please feel free to send me on my way...
I'm looking at putting together a low-level USB device protocol stack, to make a USB device that looks like a serial interface to the USB host. The objective is to be able to easily communicate with devices running the protocol stack using Minicom (Linux hosts), or Hyperterminal (Win32). The target devices won't be running Linux, or any other OS for that matter.
I know that's as easy as falling off a log in the Linux world, what with Gadgets, usbserial and all... (Thanks, Greg and company!) :^)
Does anyone know if there is a defined serial-style device class that will work with stock Linux *and* Win32 hosts? My read of the CDC specification seems to imply that you always need a driver on Win32 to make any USB device appear as a COM port, and I don't want to go there if I don't have to.
Am I reading things right, or not? All I want is to implement the bare minimum to make a USB host think I've added a COM-type port that the normal host terminal emulation programs can talk to...
Thanks!
