+1.1 Troubleshooting
+~~~~~~~~~~~~~~~~~~~
+Q: Module yealink compiled and installed without any problem but phone
+   is not initialized and does not react to any actions.
+A: If you see something like:
+   hiddev0: USB HID v1.00 Device [Yealink Network Technology Ltd. VOIP USB Phone
+   in dmesg, it means that the hid driver has grabbed the device first. Try to
+   load module yealink before any other usb hid driver. Please see the
+   instructions provided by your distribution on module configuration.
+
+Q: Phone is working now (displays version and accepts keypad input) but I can't
+   find the sysfs files.
+A: The sysfs files are located on the particular usb endpoint. On most
+   distributions you can do: "find /sys/ -name get_icons" for a hint.

 /*
- * Reserved Page provided by SAL.
+ * the reserved page
+ *
+ *   SAL reserves one page of memory per partition for XPC. Though a full page
+ *   in length (16384 bytes), its starting address is not page aligned, but it
+ *   is cacheline aligned. The reserved page consists of the following:
+ *
+ *   reserved page header
+ *
+ *     The first cacheline of the reserved page contains the header
+ *     (struct xpc_rsvd_page). Before SAL initialization has completed,
+ *     SAL has set up the following fields of the reserved page header:
+ *     SAL_signature, SAL_version, partid, and nasids_size. The other
+ *     fields are set up by XPC. (xpc_rsvd_page points to the local
+ *     partition's reserved page.)
  *
- * SAL provides one page per partition of reserved memory.  When SAL
- * initialization is complete, SAL_signature, SAL_version, partid,
- * part_nasids, and mach_nasids are set.
+ *   part_nasids mask
+ *   mach_nasids mask
+ *
+ *     SAL also sets up two bitmaps (or masks), one that reflects the actual
+ *     nasids in this partition (part_nasids), and the other that reflects
+ *     the actual nasids in the entire machine (mach_nasids). We're only
+ *     interested in the even numbered nasids (which contain the processors
+ *     and/or memory), so we only need half as many bits to represent the
+ *     nasids. The part_nasids mask is located starting at the first cacheline
+ *     following the reserved page header. The mach_nasids mask follows right
+ *     after the part_nasids mask. The size in bytes of each mask is reflected
+ *     by the reserved page header field 'nasids_size'. (Local partition's
+ *     mask pointers are xpc_part_nasids and xpc_mach_nasids.)
+ *
+ *   vars
+ *   vars part
+ *
+ *     Immediately following the mach_nasids mask are the XPC variables
+ *     required by other partitions. First are those that are generic to all
+ *     partitions (vars), followed on the next available cacheline by those
+ *     which are partition specific (vars part). These are setup by XPC.
+ *     (Local partition's vars pointers are xpc_vars and xpc_vars_part.)
  *
  * Note: Until vars_pa is set, the partition XPC code has not been initialized.

- * USB Bluetooth TTY driver, based on the Bluetooth Spec version 1.0B
- * 
- * (2001/11/30) Version 0.13 gkh
- *	- added locking patch from Masoodur Rahman <rmasoodu@in.ibm.com>
- *	- removed active variable, as open_count will do.
- *
- * (2001/07/09) Version 0.12 gkh
- *	- removed in_interrupt() call, as it doesn't make sense to do 
- *	  that anymore.
- *
- * (2001/06/05) Version 0.11 gkh
- *	- Fixed problem with read urb status saying that we have shutdown,
- *	  and that we shouldn't resubmit the urb.  Patch from unknown.
- *
- * (2001/05/28) Version 0.10 gkh
- *	- Fixed problem with using data from userspace in the bluetooth_write
- *	  function as found by the CHECKER project.
- *	- Added a buffer to the write_urb_pool which reduces the number of
- *	  buffers being created and destroyed for ever write.  Also cleans
- *	  up the logic a bit.
- *	- Added a buffer to the control_urb_pool which fixes a memory leak
- *	  when the device is removed from the system.
- *
- * (2001/05/28) Version 0.9 gkh
- *	Fixed problem with bluetooth==NULL for bluetooth_read_bulk_callback
- *	which was found by both the CHECKER project and Mikko Rahkonen.
- *
- * (08/04/2001) gb
- *	Identify version on module load.
- *
- * (2001/03/10) Version 0.8 gkh
- *	Fixed problem with not unlinking interrupt urb on device close
- *	and resubmitting the read urb on error with bluetooth struct.
- *	Thanks to Narayan Mohanram <narayan@RovingNetworks.com> for the
- *	fixes.
- *
- * (11/29/2000) Version 0.7 gkh
- *	Fixed problem with overrunning the tty flip buffer.
- *	Removed unneeded NULL pointer initialization.
- *
- * (10/05/2000) Version 0.6 gkh
- *	Fixed bug with urb->dev not being set properly, now that the usb
- *	core needs it.
- *	Got a real major id number and name.
- *
- * (08/06/2000) Version 0.5 gkh
- *	Fixed problem of not resubmitting the bulk read urb if there is
- *	an error in the callback.  Ericsson devices seem to need this.
- *
- * (07/11/2000) Version 0.4 gkh
- *	Fixed bug in disconnect for when we call tty_hangup
- *	Fixed bug in bluetooth_ctrl_msg where the bluetooth struct was not
- *	getting attached to the control urb properly.
- *	Fixed bug in bluetooth_write where we pay attention to the result
- *	of bluetooth_ctrl_msg.
- *
- * (08/03/2000) Version 0.3 gkh mdc
- *	Merged in Mark's changes to make the driver play nice with the Axis
- *	stack.
- *	Made the write bulk use an urb pool to enable larger transfers with
- *	fewer calls to the driver.
- *	Fixed off by one bug in acl pkt receive
- *	Made packet counters specific to each bluetooth device 
- *	Added checks for zero length callbacks
- *	Added buffers for int and bulk packets.  Had to do this otherwise 
- *	packet types could intermingle.
- *	Made a control urb pool for the control messages.
- *
- * (07/11/2000) Version 0.2 gkh
- *	Fixed a small bug found by Nils Faerber in the usb_bluetooth_probe 
- *	function.
- *
- * (07/09/2000) Version 0.1 gkh
- *	Initial release. Has support for sending ACL data (which is really just
- *	a HCI frame.) Raw HCI commands and HCI events are not supported.
- *	A ioctl will probably be needed for the HCI commands and events in the
- *	future. All isoch endpoints are ignored at this time also.
- *	This driver should work for all currently shipping USB Bluetooth 
- *	devices at this time :)
