UDFU(4) OpenBSD Programmer's Manual UDFU(4)NAMEudfu - Device Firmware Upgrade (DFU) Attach
SYNOPSIS
udfu* at uhub?
DESCRIPTION
The udfu driver configures a DFU-compatible device such as the Openmoko
telephone into DFU mode, then detaches it, permitting it to be attached
for read/write access as a ugen(4) device to re-flash the memory.
Note that this interferes with using the umodem(4) interface to this
device, which is sometimes needed for manual re-configuration. To enable
the use of umodem(4), it is necessary to disable udfu, either permanently
in the kernel configuration file or using boot_config(8).

The udfu driver first appeared in OpenBSD 4.5.
