I've noticed two leaks in hci_transport_usb: - The first one is pretty minor: After calling libusb_get_pollfds in usb_open, the pollfd array isn't freed (should be freed with after creating the data sources). - The seconds one is a bit more important: The data usb data sources added to the run loop are never removed or freed when calling usb_close. Besides the obvious memory leak of the data_source_t structs, the file descriptors shouldn't be used after the device (and libusb) was closed.

So i think that usb_open should store the data sources it creates, and usb_close should remove them from the run loop and free them. The only problem I see is that its a problem to add the data sources to a linked list, since they are added to the run loop's internal linked list.

HI. Thanks once more. I've decided to put the data source into an array which makes freeing them later easy. Please have a look if it work (r2612) s. As far as I know, the pollfd thing only works in linux in theory, and it didin't work with this driver, so I have (temp) disabled it's use until someone debugs/needs it on linux.
