-2.6. M105 Undocumented USB Requests
- ------------------------------
-
- The Gigaset M105 USB data box understands a couple of useful, but
- undocumented USB commands. These requests are not used in normal
- operation (for wireless access to the base), but are needed for access
- to the M105's own configuration mode (registration to the base, baudrate
- and line format settings, device status queries) via the gigacontr
- utility. Their use is controlled by the kernel configuration option
- "Support for undocumented USB requests" (CONFIG_GIGASET_UNDOCREQ). If you
- encounter error code -ENOTTY when trying to use some features of the
- M105, try setting that option to "y" via 'make {x,menu}config' and
- recompiling the driver.

+2.6. Unregistered Wireless Devices (M101/M105)
+ -----------------------------------------
+ The main purpose of the ser_gigaset and usb_gigaset drivers is to allow
+ the M101 and M105 wireless devices to be used as ISDN devices for ISDN
+ connections through a Gigaset base. Therefore they assume that the device
+ is registered to a DECT base.
+
+ If the M101/M105 device is not registered to a base, initialization of
+ the device fails, and a corresponding error message is logged by the
+ driver. In that situation, a restricted set of functions is available
+ which includes, in particular, those necessary for registering the device
+ to a base or for switching it between Fixed Part and Portable Part
+ modes.

Select Unimodem mode for all DECT data adapters. (see section 2.4.)
Problem:
- You want to configure your USB DECT data adapter (M105) but gigacontr
- reports an error: "/dev/ttyGU0: Inappropriate ioctl for device".
+ Messages like this:
+ usb_gigaset 3-2:1.0: Could not initialize the device.

Solution:
- Recompile the usb_gigaset driver with the kernel configuration option
- CONFIG_GIGASET_UNDOCREQ set to 'y'. (see section 2.6.)
+ Check whether your M10x wireless device is correctly registered to the
