I would recommend > adding this as a quirk to umass.c then. Actually I am not sure. The device when in TRU-Install mode looks like umass device, it has a place to insert a microSD card, and also cdrom drive that when mounted has the software to install on windows. When it is put in modem mode the cdrom disappears but the umass device is still there. One other thing is that when installed on a linux system there are 3 serial ports. The first port is used for the modem, one is used for a builtin gps receiver and I think the 3rd passes signal strength information to the windows software. > > There are patches attached (ubsa.c_patch, umass_c.patch, usbdevs.patch) > I am using to kill the "zeroconf" CD on the UMTS.

(Crude, but cleaner than > http://www.freebsd.org/cgi/query-pr.cgi?pr=119227) For the time being I just hard coded larger buffers - like I see you did below. Thanks for your input.
