UBTBCMFW(4) Kernel Interfaces Manual UBTBCMFW(4) NAME ubtbcmfw -- Firmware driver for Broadcom BCM2033 chip based Bluetooth USB devices SYNOPSIS To compile this driver into the kernel, place the following line in your kernel configuration file: device ubtbcmfw Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): ubtbcmfw_load="YES" DESCRIPTION The ubtbcmfw is a firmware driver for Broadcom BCM2033 chip based Blue- tooth USB devices. It provides minimal access to the parts of the de- vice required to download firmware. The ubtbcmfw driver creates three fixed endpoint device nodes. The control transfers can only happen on the control endpoint which is always endpoint 0. Control requests are issued by ioctl(2) calls. Only incoming transfers are supported on an interrupt endpoint. To perform I/O on an interrupt endpoint, read(2) should be used. All I/O operations on an interrupt endpoint are unbuffered. Interrupt endpoint is always endpoint 1. Only outgoing bulk transfers are supported on a bulk endpoint. To per- form I/O on a bulk endpoint, write(2) should be used. All I/O opera- tions on a bulk endpoint are unbuffered. Outgoing bulk endpoint is al- ways endpoint 2. The control endpoint (endpoint 0) handles the following ioctl(2) calls: USB_GET_DEVICE_DESC (usb_device_descriptor_t) Return the device descriptor. FILES /dev/ubtbcmfwN.EE Endpoint EE of device N.
