1. Product Information:
The AX88772A/AX88772 Controller is a single chip USB 2.0 to Fast Ethernet Controller. This is
an AX88772A/AX88772 NDIS driver for WinCE 5.0 embedded system. It has been qualified
under WinCE 5.0 CETK on an Intel Pentium 4 2.8GHz system with a NEC D720100AGM USB
2.0 PCI Host adapter running WinCE 5.0 CEPC X86 Platform Image.
Note: The default USB 2.0 HCD driver (EHCI) of Windows CE 5.0 Platform Builder has a
USB 2.0 device Hot-Swap BUG. The EHCI driver should be updated to fix this bug. Please
refer to Section 6 “Update WinCE 5.0 USB 2.0 HCD Driver (EHCI.DLL)”for the detail
information.

6. Update WinCE 5.0 USB 2.0 HCD Driver (EHCI.DLL)
The default USB 2.0 HCD driver (EHCI) of Windows CE 5.0 Platform Builder couldn’t handle the
USB 2.0 device Hot-Swap event well while there is a pending transfer. It will cause the USB 2.0
device driver couldn’t be loaded successfully after hot-swapping the device for a couple of times
because the physical memory (TD buffers) resources are not released by the USB 2.0 HCD driver
when the USB 2.0 device is unplugged while there is a pending transfer. This bug has been
confirmed by Microsoft and will be fixed in the future version of Windows CE 5.0.
Solution:
1. ASIX provides an updated EHCI.DLL file for standard X86 CE/PC platform.
1-1. Copy the updated EHCI.DLL file into the $(_WINCEROOT)\PBWorkspaces
\<YourProjectName>\RelDir\CEPC_x86_Release subdirectory.
1-2. Run "Make Run-Time Image" to create the NK.BIN image file.
2. Customer manually modifies the cpipe.cpp file in the $(_WINCEROOT)\PUBLIC
\COMMON\OAK\DRIVERS\USB\HCD\USB20\EHCI subdirectory and rebuild
a new EHCI.DLL driver for their specific WinCE BSP platform.
2-1. Modify the cpipe.cpp file in the $(_WINCEROOT)\PUBLIC\COMMON
\OAK\DRIVERS\USB\HCD\USB20\EHCI subdirectory to remove below
two statements.
<<< In the cpipe.cpp file >>>
void CQueuedPipe::AbortQueue( void )
{
….
ASSERT( m_pUnQueuedTransfer == NULL);
if (m_pQueuedTransfer) {
RemoveQHeadFromQueue();
// m_pQueuedTransfer; //Remove this line
m_pQueuedTransfer ->AbortTransfer();
GetQHead()->InvalidNextTD();
m_pCEhcd->AsyncBell();// Ask HC update internal structure.
Sleep(2);// this sleep is for Interrupt Pipe;
m_pQueuedTransfer->DoneTransfer();
// m_pQueuedTransfer = NULL; //Remove this line
delete m_pQueuedTransfer;
m_pQueuedTransfer = NULL;
InsertQHeadToQueue() ;
}
ASSERT(m_pQueuedTransfer == NULL);
….
}

2-2. Rebuild EHCI driver by select "Build and Sysgen Current Project" from usb20 project
menu. (See below picture)
2-3. Check if the EHCI.DLL file in the $(_WINCEROOT)\PBWorkspaces
\<YourProjectName>\RelDir\CEPC_x86_Release subdirectory is
updated successfully or not.
2-4. Run "Make Run-Time Image" to create the NK.BIN image file.

7. How to configure WinCE 5.0 to run the SROM Programming Tool?
Before running AX88772A/AX88772 SROM Programming Tool (eeprom.exe), users need to add
the “NDIS user mode I/O driver”in the WinCE 5.0 platform and then select “Build and Sysgen”
from “Build OS”menu to rebuild the boot image file.
Add this into your platform

8. How to support AX88772A/AX88772 board with different Vendor ID/Product
ID?
The AX88772A/AX88772 WinCE 5.0 driver supports AX88772A’s default VID/PID
(0B95h/772Ah) and AX88772’s default VID/PID (0B95h/7720h). If the VID/PID of your
AX88772A/AX88772 board are different from AX88772A’s/AX88772’s VID/PID, please follow
below procedures to change the VID/PID registry setting of AX88772A/AX88772 WinCE 5.0
driver to support your AX88772A/AX88772 board.
8-1. Change the VID/PID setting from the Registry File
1. Add the following registry setting highlighted in below blue text in the
$(_WINCEROOT)\PBWorkspaces\<YourProjectName>\RelDir\CEPC_x86_Release\PROJE
CT.REG file, and then change the VID/PID registry setting to meet the real VID/PID of your
AX88772A/AX88772 board.
Note: The VID/PID registry values in the PROJECT.REG file are demonstrated in
“decimal” numbers. For example, the “2965”means 0B95h in a hexadecimal number;
meanwhile, the “30496”means 7720h in a hexadecimal number. The VID/PID registry
setting “2965_30496”is for AX88772’s default VID/PID (0B95h/7720h), and the VID/PID
registry setting “2965_30506”is for AX88772A’s default VID/PID (0B95h/772Ah).
