[maemo-developers] AW: PC Suite communication

[From: André Hänsel]

Hi,

for two reasons:
a) It requires plugging in the cable and I like how it syncs automagically
via Bluetooth when I enter the office
b) I have even less experience with windows USB in general and USB composite
devices, so making a driver for the g_nokia USB networking is quite a
challenge (see also

Regards,
André
