Hi, I am currently trying a setup of using dummy_hcd with f_obex and get get freezes each time. Here's what I do (linux-2.6.33): $ modprobe dummy_hcd $ modprobe g_serial use_acm=0 use_obex_1 n_ports=1 I then attach a local version of obexpushd (I'm the author) to /dev/ttyGS0 and when looking for it, I get: Found 1 usb devices. Device 0: Manufacturer: Linux 2.6.33 with dummy_udc Product: Gadget Serial v2.4 Serial: (null) Description: CDC Object Exchange (OBEX) However, when trying to transfer anything with obexftp (e.g. something simple like a directory listing), I immediately get a hard lock-up. When doing the same thing with a connected SE K800i, it works just fine. Any ideas?
