There is a windows program that will sniff the USB bus and record all the
communications with a device.  I don't know the name of it but it's been
referenced on the EVDO forums a bit.

I've also read of some hardware solutions, but they've all seemed a bit more
trouble than they are worth.

There is a windows program that will sniff the USB bus and record all the communications with a device.&nbsp; I don't know the name of it but it's been referenced on the EVDO forums a bit. I've also read of some hardware solutions, but they've all seemed a bit more trouble than they are worth.
