We had also reports from users of Gigaset M105 who could use the drivers
with SX 100 and CX 100 ISDN bases (only in unimodem mode, see section 2.4.)
If you have another device that works with our driver, please let us know.
- For example, Gigaset SX205isdn/Sinus 721 X SE and Gigaset SX303isdn bases

- they should work just as well; but so far we are lacking positive reports

+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 disabled in the driver by default for safety
+ reasons but can be enabled by setting the kernel configuration option
+ "Support for undocumented USB requests" (GIGASET_UNDOCREQ) to "Y" and
+ recompiling.
