UBTBCMFW(4)

💖 ubtbcmfw(4) — the Kernel Interfaces Manual page for your Broadcom BCM2033 firmware driver 💖

🌸 NAME 🌸

ubtbcmfw — firmware driver for Broadcom BCM2033 chip based Bluetooth USB devices. Like, that's the whole vibe bestie 💅

✨ SYNOPSIS ✨

Okay so, 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 Bluetooth USB devices. It provides minimal access to the parts of the device required to download firmware. Lowkey iconic 👑

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. The interrupt endpoint is always endpoint 1.
• Only outgoing bulk transfers are supported on a bulk endpoint. To perform I/O on a bulk endpoint, write(2) should be used. All I/O operations on a bulk endpoint are unbuffered. The outgoing bulk endpoint is always endpoint 2.

The control endpoint (endpoint 0) handles the following ioctl(2) calls:

• USB_GET_DEVICE_DESC (usb_device_descriptor_t) — returns the device descriptor. Slay 🫶

🎀 FILES 🎀

• /dev/ubtbcmfwN.EE — endpoint EE of device N.

⭐ HISTORY ⭐

The ubtbcmfw driver was implemented in FreeBSD 5.0. A little retro, very main character energy ✨
