1. INSTALLATION NOTES

Please refer to Qualcomm document 80-VB717-1 Rev B for detailed instructions on
driver installation.

----------------------------------------------------------------------

2. MAJOR FEATURES

1) The driver is designed to be reentrant, which allows multiple device
   connections on Windows XP/Vista.
 
2) The driver is designed to be running safe with Intel Hyper-Threading processor
   and multi-processor systems with Windows XP.

3) Support Plug&Play, and power management (system standby and hibernation). USB
   selective suspension will be supported in the future.

4) Support multiple control clients through QUALCOMM MSM Interface (QMI).

----------------------------------------------------------------------

   under arbitary system context. (1.0.3.0)

2) Fixed the BSOD issue triggered by a race condition during IRP completion.
   (1.0.3.0)

3) Provided a way to work around a BSOD issue on Windows XP when system came
   out of standby with NIC's power management disabled. (1.0.3.0)

4) Fixed a race condition under which outstanding I/O might not be cleaned
   up when the network adapter was disabled. (1.0.3.1)

5) Added IP-only mode support. (1.0.3.2)

6) Added additional remove lock to avoid stray-away QMI operations. (1.0.3.2)

   efficiency. (1.0.3.2)

8) Added statistics summary to debug output to aid debugging. (1.0.3.2)

9) Changes have been made so that the driver does not request QMI statistics
   from the device, the driver maintains its own statistics instead. (1.0.3.2)

10) Enhanced error handling for device removal. (1.0.3.2)

11) Added QCMP_TEST_MODE to support development/testing. The feature would be
    enabled for engineering builds only. (1.0.3.2)

   to avoid system sleep failure when the hub controller is armed for remote wakeup.
   (1.0.3.4)

15) Changes were made to avoid double completion of a system power IRP when a series
   of non-consistent system power IRPs (e.g query-s3 followed by set-s0 and followed
   by set-s3) are dispatched to the driver. (1.0.3.4)

16) Added IOCTL support for retrieving device ESN/IMEI/MEID. (1.0.3.5)

17) Added support for PID 900B. (1.0.3.6)

----------------------------------------------------------------------

4. KNOWN ISSUES:

   It's been observed that the Qualcomm USB driver could trigger bugs in older
   versions of McAfee mini-firewall driver mvstd5x.sys. McAfee has suggested
   that users obtain McAfee VirusScan patch 14 or later patches for bug fixes.

   Compilation flag QCUSB_TARGET_XP should NOT be defined with this version due to
   unsolved issues with XP-specific function calls.

   McAfee Intermediate Filter driver may cause IPV6 connection failure. If such
   a failure happens, a user may either need to remove the McAfee driver from the
   device stack or contact McAfee for solution.

   Driver verifier (verfiler.exe) may cause throughput degradation.

----------------------------------------------------------------------

5. BUILD INFORMATION:

   The following compilation flags are defined for customers to build the driver
   to debug various issues related to host and device, they are not recommended
   for other purposes.
      ENABLE_LOGGING
      QCUSB_ENABLE_LOG_REC
      QCUSB_DBGPRINT
      QCUSB_DBGPRINT2
      QCUSB_TARGET_XP

   IMPORTANT!!! To achieve best security and performance, all of the above features
   should be turned off for commercial distributions. The free build binaries are
   recommended for commercial distributions.
