You need HAL or some OS-specific notification mechanism. Libusb does not provide notifications for new devices. But the OBEX server/client roles are independent of underlying transport roles: the other side on an incoming TCP connection can be an OBEX server or a client. Same is now possible with USB, and I think I've seen a Nokia phone with a Bluetooth OBEX profile that implemented a server role. > > Why?

Not sure but Solaris comes to my mind. Additionally, bluetooth > support is optional when building. My patch will not add a bluetooth dependency, no worries :) You can hardcode the UUID in your application, or use one provided by bluez. > > > Great.

Never seen a phone from SE that has this. Nokia does but > not all models (known ones?). All of Nokia's S60 phones, and most of S40 phones. Also SE has a few phones, but I'm not sure which ones. -- Alexander ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
