UDFU(4)                   OpenBSD Programmer's Manual                  UDFU(4)

NAME
     udfu - 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 de-
     vice, 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).

SEE ALSO
     ugen(4), uhub(4), usb(4), boot_config(8), config(8)

HISTORY
     The udfu driver first appeared in OpenBSD 4.5.
