Has anybody got any expereinec with these ? I am playing around with a small device (an scrypt ASIC) which presents itself to the OS as a serial port, using this chipset. When I plug it in I get this: ugen0.2: <STMicroelectronics> at usbus0 umodem0: <STMicroelectronics STM32 Virtual COM Port, class 2/0, rev 2.00/2.00, addr 2> on usbus0 umodem0: data interface 1, has no CM over data, has no break So it thinks it is a USB modem as far as I can make out ? I get a /dev/ttyU) device in /dev, but I do not think the device should present istelf as a modem. I have Linux software which is supposed to talk to the chip via a tty, and this does nothing when presented with the /dev/ttyU0 device. I also cannot get anything out of it. I havent dug very far into it yet, but was wondering if anyone had any ideas - this is the first time I've seen 'umodem' come up. cheers, -pete.
