Hardware specifics
Neo1973 and CDC ACM
The Neo1973 u-boot boot loader contains support for obtaining the boot loader prompt over USB CDC ACM.
The Openmoko kernel also contains CDC ACM device support, contained in the g_serial.ko kernel module.
Host PC and CDC ACM
Linux
Linux has a generic CDC ACM host-side implementation in the kernel module cdc_acm.ko
On 2.6.25 this is at "Device Drivers -> USB support (USB_SUPPORT [=y]) -> Support for Host-side USB (USB [=m]) -> USB Modem (CDC ACM) support (USB_ACM)"
Windows
