Does your computer have a media card reader? If so, that's probably where all those drives are coming from. Each one of those card types has an allocated virtual drive to load to.

Now, to get to your actual problem, it sounds like you're having a problem with some USB peripheral, the drives appearing and disappearing is probably just a symptom of the real problem (i.e. it keeps trying to refresh). The problem can really be anything USB (including your keyboard or mouse) or even one of the USB chips that's malfunctioning (or the power to it is dropping below whatever is it's minimum).

To troubleshoot:
- Disconnect ALL external USB items and see if problem appears.
- Try to find old style keyboard and mouse to drive.
- Disable the media card reader on the device manager if there.
- Start in safe mode and see if problem occurs there.
- If problem still persists... you'll need more experienced help (need to check voltage levels to USB chips, may be problem with motherboard or powersupply... more likely motherboard since the power to the chips should be going through a regulator on the motherboard).

Thanks, I'll try all this

Hi, I have a sample OSR USB board and I have written a sample driver for this USB board.

I have built this driver and able to install.

But I am not able to debug this driver using Windbg since it is kernel driver.

OS: Win7

#include ntddk.h
 
DRIVER_UNLOAD DriverUnload;
 
void DriverUnload(PDRIVER_OBJECT pDriverObject)
{
DbgPrint("Driver Unload\n");
}

NTSTATUS DriverEntry(PDRIVER_OBJECT pDriverObject, PUNICODE_STRING pRegistryPath)
{
pDriverObject->DriverUnload = DriverUnload;
DbgPrint("Driver Entry : Hello Windows Device Driver World!\n");
return STATUS_SUCCESS;
}

Can anybody help me in debugging my driver?

In system config on the target you need to enable kernel debug specifying firewire of serial.

Hook the target to the host with tht relevant cable.

Turn off the target.

Run windbg on the host and set it to kernel debug on the relevant interface (firewire or serial).

Restart the target and it should connect and you will see a lot of debug data.

You then set the path in windbg for the symbols and code for your driver (and use the global microsoft symbol server for their code, search in help for symsrv), then you can set breakpoints and step through your code.

So you are a supposedly Senior Software developer, yet you cant read simple documentation, for which there is plenty available, and then, when I give you the answer you dont ever bother responding.

What a joke you are!

In Windows 7 there is a sequence of mouse clicks on various icons which will display the buffer size of a given Com Port.

I can't remember that sequence at this moment.

(It's almost always 4096, for whatever reasons may exist)

If possible, I want to change it to 1024 (as a user; not in software)

For the moment, can someone help my failing brain with the secret sequence of clicks and icons that display the port buffer size of the USB BlueTooth adapter ?

Hi all,

I have a Win 7 64bit hp 8570w laptop. I've set the screen server to be active in 5 minutes. Other power management settings are as follows.

Dim the display - 5 minutes
Turn off the display - 10 minutes
Put the computer to sleep - 30 minutes

However, like around 2 minutes after I didn't use the laptop, it goes to sleep mode. Any idea why really happen that?

If required more information please let me know.

Thanks in advance Smile | :)

If you've never failed... You've never lived...

Is this on mains power or battery? Are you sure that you set the correct power save profile as the active one?

This is from main power. And yes, I set the correct power profile too. I cannot post a screenshot here, since there is no way to upload an image Smile | :)

If you've never failed... You've never lived...

Sounds like a fault with the PC. I suggest you call HP support.

Hmm. I disabled all the power plans (set timers to never) and the issue is still the same.

So I'll contact the support and see.

Yeah, this sounds like something specific to your hardware.

Everyone might have watched IRON MAN series, in part 2 of the series he uses surface computers containing a transparent glass slab , when i read about the details it was like there were laser-integrated motion sensing projectors which just sensed his hand signal and projected the images but i thought whats the difficulty in implementing a surface comp and i even heard MICROSOFT tried one surface computer which did not succeed

So what is your question?

why is it getting hard to implement a surface comp when the technology has advanced to heights

It isn't. Why don't you try asking a proper question?

Sir,i m talking about the comps which are used in the movie , it like just two glass sheets , i m talking about their implementation . I just wanted to know whats the technology to implement them in reality whereas in the movie its just like a screen on which an image is projected. Usually there seems to be a controlling unit below the screen. Its like a normal comp with it screen made larger.

You do realise that movies are not reality?

no offense Sir but the microsoft surface comp as in my view is just an enlarged touch screen phone with a good amount processors waiting to recognise the signals Smile | :)

Sorry, but I really don't understand what your problem is. If you just want to criticise Microsoft products then you maybe need to go to the Lounge, or some other web forum.

oh not really that was a joke sir i m planning to build one in the near future, i even had a page bookmarked but by mistake i deleted it in that they had given a brief info about polishing the glass surface and all stuff , so thought might get some ideas of mistakes were done by others and i didnt want to repeat them, since i want to program the LANs now at present as my project in my college ,my holidays are going on so thought i could do something related to hardware Smile | :)

Hi Guy's

Here's a tough one

I need to find a device that i can use to secure access to a fingerprint reader.
Basically what I need is a device that:
1) has a female usb input and a male output with a controller device in the midle
2) once joinced to the fingerprint device it will be epoxied together
3) I want then to be able through software to send a command to the dongle to unlock the use of the fingerprint device

Can anyone point me in the direction of something like this ?
What my company wishes to do is restrict use of the device by any software other than the software that it was intended for.

Cheers

Hey everyone I have this exotic project called SpaceData, it's a project for creating a wormhole and black hole generator in one massive device.

A black hole crushes everything to a small particle, literally. A wormhole creates two gateways at two different points in the universe or space and sucks in an object faster than the speed of light into and forces it out of the other side of the portal.

THE GOODS OF THIS DEVICE WOULD BE: Sucking up gamma ray bursts, massive asteroids, deadly solar flares or bursts from the sun ,and if they existed, an alien invasion. Basically a planetary defense for planet Earth.

The problems I will be facing (at the top of my head) is...

I. Funding
You need money in order to build any device.

II. Resources
I need the steel, iron, power, and chemistry that will make up this device.

III. Maintenance
Like any device it will deteriorate and go bad, and like device like this left unchecked, if it opens a black hole or worm hole per say in anywhere sensitive or where it's not sup post to, serious bad things WILL happen. Lets just say hell and devastation on planet Earth.

IV. Engineers
I will need people at my "own page" developing this device together, because one mind developing such an exotic and extremely powerful device is NOT practical; it would take more than my life! to build or even think about making such a device.

V. Device Security
So much power going into the wrong hands can be "hell on earth" with a thing like this. So you need physically impassible barriers to protect this device from the wrong hands. Also trustworthy people with self-control that will protect the device instead of activating behind my back or in front of my eyes.

VI. Personal Security
More than likely, if people know I created this device and/or have it in my possession and/or can use it at my disposal, there will be killers and terrorists coming after me wanting to destroy me or torture me making me feel physical and emotional agony my entire life. Not only that if my own government and/or other governments knows about this, whether by a spy satellite, a spy agent, a word of mouth, or the news, my own county or nation and it's military will be going against me as well, because a good apple can turn rotten, can it not? and my friends will be brainwashed by my government or any kind of enemy that I will be facing and sooner or later I will have everyone against me, including anyone who reads this post and people on CodeProject(R). Just for the sake of (protecting and) having a device.

What I'm asking is, is building and maintaining a device like this worth it? Could I put this on another planet?, Or in a world like this there's too many problems could occur? (like all listed above)

Simple Thanks and Regards,

I think this probably belongs on a "Trekkies" website.

One of these days I'm going to think of a really clever signature.

Could you provide me a link please?
