I know after Windows XP release Universal USB Storage Driver is not an issue for any USB. Two days back, I was facing USB detection issue. My Computer was not recognizing my portable hard disk either. Finally on Sunday, I got two hours to fix critical problem and share my findings with you with solution. I am share my findings based on Microsoft Windows 7 only.
"USBSTOR.sys" file is USB Mass Storage Driver for detect USB Mass Storage Device(s). You can find it in folder location "C:\Windows\System32\drivers". ‘.SYS’ files communicate with Operating System directly and guide Operating System what to do with device and how to do.
Operating System has one utility (so called, Driver Detection/New Hardware Found) for new device detection and registration for correct version of device driver to communicate with Operating System. Driver Detection utility needs INF and PNF file for device detection and registration for communication with hardware. You can find them in folder location, "C:\Windows\inf".
[Additional Information, INF file has all driver setup information and PNF file has some dependency and additional information of driver (in nontechnical words) (Technical team is Precompiled Setup Information).]
Some time USB Mass Storage Device has problems due to driver installation and un-installation frequently OR due to any possible bug of installer/setup. Installer can delete .INF, .PNF and/or .SYS file(s).
Windows 7 has almost every Device Driver backup in folder location, "C:\Windows\System32\DriverStore\FileRepository\". Go there and search folder "USBStor.inf_******" (* is driver identity number). It will have three files of USB Mass Storage Driver. Please follow instructions to restore them,
1. Copy "usbstor.inf" file and "usbstor.pnf" file, and place in location "C:\Windows\inf".
2. Copy "usbstor.sys" file and place in location "C:\Windows\System32\drivers".
3. Reboot Operating System.
4. Say AHO! After login. (Please note without AHO! USB will not work. A Joke)
5. Insert USB and use it.
Again AHO!

You can learn easily by Google, ‘How to use .config file in log4net?’. My project has two different type of logging file. I want to centralize logging location configurable. Following code will help you to read log4net “File Appender” to get “File” tag value (file path).
public static log4net.Appender.IAppender[] GetAllAppenders()
{
ArrayList appenders = new ArrayList();
log4net.Repository.Hierarchy.Hierarchy h =
(log4net.Repository.Hierarchy.Hierarchy)log4net.LogManager.GetLoggerRepository();
appenders.AddRange(h.Root.Appenders);
return (log4net.Appender.IAppender[])appenders.ToArray(typeof(log4net.Appender.IAppender));
}
This function will give you all Appenders defined under log4net tag in .config file.
public static FileAppender GetFileAppender()
{
IAppender[] appenderList = GetAllAppenders();
FileAppender fileAppender = null;
foreach (IAppender appender in appenderList)
{
if (appender.GetType().FullName == typeof(RollingFileAppender).FullName)
{
fileAppender = (FileAppender)appender;
break;
}
}
return fileAppender;
}
This function will give return File Appender to get all information defined regarding File in RollingFileAppender under log4net tree.
FileAppender apprender = GetFileAppender();
log_path = apprender.File;
This code will give you File Path defined in .config file using log4net tag tree. FileAppender instance has some other useful information which may required in any log as per need.
Best of Luck!
End with Aho!

Sample code can help you to use excel sheet as database.
private static OleDbDataReader myReader;
private static DBManager dbObject;
public static void readDatabaseDate( string filePath, string selectQuery )
{
String conString = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + filePath + ";" + "Extended Properties=Excel 8.0;";
dbObject = new DBManager( conString );
dbObject.open( );
myReader = dbObject.SelectQuery( selectQuery );
}

Specification of Pakistan Flag
"That this assembly resolves that the national flag of the federation of Pakistan be of the following description.
"A dark green rectangular flag in the proportion of length and width 3:2 with a white vertical bar at the mast, the green portion bearing a white crescent in the centre and a five-pointed white heraldic star. The size of the white portion being one-fourth the size of the flag, nearest the mast, the remainder three-fourths being dark green. the dimensions of the crescent and star are obtained as follows:
"Draw the diagonal from the top right hand corner to the bottom left corner of the green portion. On this diagonal establish two points ‘A’ and ‘B’. Point ‘A’ at a distance equidistant from top right and bottom left hand corners of the green portion, i.e. the centre of the green portion. Point ‘B’ at a distance from the top right hand corner equal to 13/20th the width of the flag. With centre point ‘A’ and radius 1.1/4th the width of the flag describe a second arc. The enclosures made by these two arcs form the crescent. The dimensions of the five-pointed white heraldic star are determined by drawing a circle 1/10th the width of the flag. The circle surrounds the five points of the heraldic star. The star lies with one point on the diagonal at a point where the larger arc of the crescent, if completed, cuts the diagonal."

Although windows have “itoa” function but I did not find it in Linux. That time, I did Google and found a beautiful function for conversion of integer value into character string. Sample code is given below,
#include <stdio.h>
void main()
{
char fun[80];
int value = 1943743;
sprintf(fun, "%d", value);
}
Enjoy and say AHO!

Today, I am going to share some development guide lines for develop Linux-Kernel Module with NetFilter. Inshah-Allah! It will be helpful for newbie.
- Before anything, you should do pencil work around your problem/task and LAB setup.
- After complete your LAB setup, your should take understanding of all technologies related to development task. These are given below,
- Linux Kernel Version Understanding, Selection and Compilation.
- I would recommend to read compilation article. You will learn a lot but for shortcut, I am listing following commands that will be use for Linux Kernel Compilation.
- # cd /tmp
- # wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.25.tar.gz
- # tar –zxvf linux-2.6.25.tar.gz –C /usr/src
- # cd /usr/src
- # make menuconfig
- # make
- # make modules
- # make modules_install
- # make install
- (Reboot system and enjoy Linux-2.6.25 Kernel)
- I would recommend to read compilation article. You will learn a lot but for shortcut, I am listing following commands that will be use for Linux Kernel Compilation.
- Linux Kernel Code Reading (I use vs2k5 IDE for code reading, if you know any good Open Source IDE then please let me).
- Linux Kernel Module Programming with v2.6 (html, pdf) including memory allocation and deletion (first, second).
- Protocol Understanding at packet level.
- Understanding of NetFilter Programming (first, second, third).
- Understanding of SK_BUFF structure for packet operation (first, second, third, fourth, fifth).
- Good development practices.
- Linux Kernel Version Understanding, Selection and Compilation.
- Start Development and after complete your task say, “AHO!”.
I have developed Linux Kernel Driver (for Linux Kernel 2.6.25) for Gateway with in fifteen days to change one of the protocol behavior. I did not have any Linux development experience before this task. I am dimmest person in world but you are not. You can do it! Come On Say, “YES, I Can!”. Don’t forget to say, “AHO!” after complete your task.

Following commands can give network connections information,
- # netstat -tulpan
- # lsof –i
Command#1 (netstat –tulpan) will give you connections information, but I did not find any way to kill connection after get information from it.
Command#2 (lsof –i) will give you useful connections information and PID of connections as well. You can kill that session using PID.

Given code is working perfect to generate new copy of NDIS_PACKET,
NDIS_STATUS
CreateNewSendNdisPacket(IN NDIS_HANDLE SendPacketPoolHandle,
IN PNDIS_PACKET pkt_old,
IN PGUINT8 pkt_raw,
IN GUINT32 pkt_len,
OUT PNDIS_PACKET * pkt_new)
{
NDIS_STATUS Status;
NdisDprAllocatePacket(&Status, pkt_new, SendPacketPoolHandle);
if(Status == NDIS_STATUS_SUCCESS)
{
PNDIS_BUFFER MyBuffer;
PSEND_RSVD SendRsvd;SendRsvd = (PSEND_RSVD)((*pkt_new)->ProtocolReserved);
SendRsvd->OriginalPkt = pkt_old;
NdisAllocateBuffer(&Status, &MyBuffer, SendPacketPoolHandle, pkt_raw, pkt_len);
if(Status == NDIS_STATUS_SUCCESS)
{
NdisChainBufferAtFront((*pkt_new), MyBuffer);
(*pkt_new)->Private.Flags = NdisGetPacketFlags(pkt_old);
}
}
return Status;
}
NDIS_STATUS
CreateNewRecvNdisPacket(IN NDIS_HANDLE RecvPacketPoolHandle,
IN PNDIS_PACKET pkt_old,
IN PGUINT8 pkt_raw,
IN GUINT32 pkt_len,
OUT PNDIS_PACKET * pkt_new)
{
NDIS_STATUS Status;NdisDprAllocatePacket(&Status, pkt_new, RecvPacketPoolHandle);
if(Status == NDIS_STATUS_SUCCESS)
{
PNDIS_BUFFER MyBuffer;
PRECV_RSVD RecvRsvd;RecvRsvd = (PSEND_RSVD)((*pkt_new)->MiniportReserved);
RecvRsvd->OriginalPkt = pkt_old;NdisAllocateBuffer(&Status, &MyBuffer, RecvPacketPoolHandle, pkt_raw, pkt_len);
if(Status == NDIS_STATUS_SUCCESS)
{
NdisChainBufferAtFront((*pkt_new), MyBuffer);
(*pkt_new)->Private.Flags = NdisGetPacketFlags(pkt_old);
}
}
return Status;
}
Don’t forget to delete memory after send complete. I have used above functions in PassThru example of NDIS-WDK.

GUINT16 ComputeChecksum(PGUINT16 pseudo_hdr, PGUINT16 ptcp_hdr, PGUINT16 pdata, GUINT32 dataSize) {
guint32 checksum = 0;
guint32 nleft = 0;
nleft = SIZE_PSEUDO_HDR;
while(nleft > 1) {
/* This is the inner loop */
checksum = checksum + *(pseudo_hdr++);
nleft = nleft – sizeof(guint16);
}
nleft = SIZE_TCP_HEADER;
while(nleft > 1) {
/* This is the inner loop */
checksum = checksum + *(ptcp_hdr++);
nleft = nleft – sizeof(guint16);
}
nleft = dataSize;
while(nleft > 1) {
/* This is the inner loop */
checksum = checksum + *(pdata++);
nleft = nleft – sizeof(guint16);
}
if(nleft)
checksum = checksum + *((pguint8)pdata);
/* Fold 32-bit sum to 16 bits */
checksum = (0xFFFF&(checksum >> 16)) + (checksum & 0xffff);
checksum = (checksum & 0xffff) + (0xFFFF&(checksum >> 16));
return (guint16)(~checksum);

While working on Microsoft Device Driver domain, I found following most active and helpful forums,
1) OSR-Online: http://www.osronline.com
You can configure OSR-Online forum on email client and given client will be helpful for you.
http://www.osronline.com/page.cfm?name=NewsReaderInfo
2) Microsoft NNTP Server: msnews.microsoft.com
Following groups are available on Microsoft forum,
1. microsoft.public.development.device.drivers
2. microsoft.public.windowsxp.device_driver.dev
You can configure Microsoft NNTP server on email-client using above “OSR-Online Forum Configuration” process but you will use “msnews.microsoft.com” for Microsoft NNTP Server address. You will not need authentication cardinality to connect Microsoft NNTP Server.
NOTE: Some time few consultants will discourage you to use forums for help and will ask you to get consultancy from them. Please do not underestimate yourself and try google and other forums for help because “Everything possible but nothing is impossible”.
