Hi all,

I have a hardware(controller-based) USB modem(Zoom 2985-00-00C) that is
identified under Liunx by acm driver and can be accessed through
/dev/ttyACM0 and with some tools like “cu” and AT command set. This means
that it supports CDC/ACM.
But under FreeBSD 6.1(which have the latest umodem driver) with loaded
ucom and umodem driver into kernel, after attaching the modem to the USB
port, these messages appear on screen:

     ucom0: data interface 1, has CM over data, has break
     ucom0: Could not find data bulk in
     device_attach: ucom0 attach returned 6

and there is no ucom0 or any other appropriate devices in /dev directory
and the modem does not work.
With due attention to successful working under Linux, is there any hope to
solve this problem under FreeBSD? Is it necessary to update umodem driver
or there is an easy way?

Best regards
