2.6. M105 Undocumented USB Requests

The Gigaset M105 USB data box understands a couple of useful, but

2.7. 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. For the M105, these commands require the "Support for undocumented
USB requests" configuration option (see section 2.6.) to be enabled.

Solution:
Check whether your M10x wireless device is correctly registered to the
Gigaset base. (see section 2.7.)
