  • Problem with USB drivers (Windows-XP)

    - by Carl
    I obtained the drivers from the manufacturer for my HT-Link NEC USB 2.0 2-port Cardbus card. When I plugged in the card before I got the drivers, 3 new entries showed up in the Device Manager - two "NEC PCI to USB Open Host Controller" and one "Standard Enhanced PCI to USB Host controller." With the card plugged in, I uninstalled those two drivers. I then removed the card. I copied the new drivers to c:\windows\system32\drivers and the .inf file to c:\windows\inf. I also copied the drivers & inf to a new directory called c:\windows\drivers\ousb2. I reinserted the card. Windows automatically installed the same drivers as before. I selected 'update driver' on the "NEC PCI to USB..." entry and didn't see any other options. I then selected 'have disk' and pointed to c:\windows\drivers\ousb2 and got a message "The specified location does not contain information about your hardware." I then selected 'update driver' on the "Standard Enhanced PCI to USB...," and manually selected "USB 2.0 Enhanced Host Controller" (OWC 4/15/2003 2.1.3.1). Windows then automatically found a USB root hub, and I manually selected "USB 2.0 Root Hub Device" (OWC 4/15/2003 2.1.3.1). Now there are two sections in the Device Manager titled "Universal Serial Bus controllers." I plugged in my external USB hard disk adapter, and "USB Mass Storage Device" was added to the first set. Here's how it looks (w/drivers from the properties): [Universal Serial Bus controllers] Intel(R) 82801DB/DBM USB 2.0 Enhanced Host Controller - 24CD (6/1/2002 5.1.2600.0) Intel(R) 82801DB/DBM USB Universal Host Controller - 24C2 (7/1/2001 5.1.2600.5512) Intel(R) 82801DB/DBM USB Universal Host Controller - 24C4 (7/1/2001 5.1.2600.5512) Intel(R) 82801DB/DBM USB Universal Host Controller - 24C7 (7/1/2001 5.1.2600.5512) NEC PCI to USB Open Host Controller (7/1/2001 5.1.2600.5512) NEC PCI to USB Open Host Controller (7/1/2001 5.1.2600.5512) USB Mass Storage Device USB Root Hub (7/1/2001 5.1.2600.5512) (5 more USB Root Hubs - same driver) [Universal Serial Bus controllers] USB 2.0 Enhanced Host Controller (OWC 4/15/2003 2.1.3.1) USB 2.0 Root Hub Device (OWC 4/15/2003 2.1.3.1) When I unplug the card the two "NEC PCI to USB..." entries in the first set disappear, and the whole second set disappears. (I unplugged the hard disk adapter first...) The hard disk adapter still doesn't work in that Cardbus card with the new drivers. I don't think the above looks right - a second set of USB controllers listed in the Device Manager, and the NEC entries still in the first set, and the the USB mass storage device still in the first set. Any help appreciated. (Windows XP PRO SP3 w/all current updates.)

  • Is it better to use N WiFi or Cat5e ethernet for large file transfers?

    - by Seth
    I have a network containing 802.11 N WiFi Devices and gigabit ethernet devices, however using only Cat5e wiring. I know that if I used Cat6, the ethernet would be much faster however if I need to transfer a large file between a device thats connected normally connected via ethernet and a device thats normally connected via WiFi, would it be advantageous to bother plugging the WiFi device in to the network? or should I switch the ethernet device to WiFi? or does it really matter?

  • Windows 7 sound control is not flexible.

    - by jon
    I would like to be able to listen to music on both of two audio output devices, but Windows 7 seems to only allow me to select one or the other as the Default device. When device A is the Default device, device B is muted; and vice versa. This seems to be stunningly inflexible. Since Windows 7 is unable to do this, can anyone recommend any add-on software that would control the hardware more flexibly and thoughtfully?

  • bluetooth connection using pybluez

    - by srj0408
    I am working on bluetooth not exactly on bluetooth stack-development but to use bluetooth in one of my project. I had done all that before using some of the py-bluez commands like hciconfig, hcitool scan , then simple-agents and using serial module inside python. But that was quite random. We were able to connect only one specific device based on its bluetooth address and there was no facility of reconnection once the devices are disconnected. Now i want to try out this stuff in a sequential manner like this (i am doing that all on a RPI and for at present on ubuntu 12.04.) i) Store some names in a file along with some other information with respect to that device. ii) Run a script to find out the device in locality with those names and if any one if found, report that. For this step, i had taken a reference from BTBook , made available from MIT. Below is the script for the same, but that script only search for the single name. from bluetooth import * target_name = "XT1033" target_address = None nearby_devices = discover_devices() for address in nearby_devices: if target_name == lookup_name( address ): target_address = address break if target_address is not None: print "found target bluetooth device with address ", target_address connect_socket(target_address); else: print "could not find target bluetooth device nearby" iii) Connect the device using client sock. But i dont have any device on which i can write a simple python script. My client can be any device that will be publishing data. Now i came through a script in the same book, that actually connect to a client requesting permission to connect to server. from bluetooth import * port = 1 server_sock=BluetoothSocket( RFCOMM ) server_sock.bind(("",port)) server_sock.listen(1) client_sock, client_info = server_sock.accept() print "Accepted connection from ", client_info data = client_sock.recv(1024) print "received [%s]" % data client_sock.close() server_sock.close() here client_sock, client_info = server_sock.accept() provide the client address and port requested to be connected. Can i pass address obtained from the earlier script to this, so that it connect server to the client? iv) Then if client get disconnected, re-connect(a simple polling can be used.) All this stuff can be done using bash and py-bluez functions but i want to do that in a sequential manner.I am not a master in python but i can do some small stuff. Can any one guide me for the same or can direct me to more usefull resource through which i can continue my coding part after finding the "X", "Y" named devices.

  • ergonomics: what's better; trackball, ergonomic mouse or some other pointing device (a-la touchscree

    - by mauriciopastrana
    So I bit into the hype and recently purchased an apple wireless keyboard and that evil bar-of-soap thing apple makes for a mouse. Couple of hundred dollars later and this is where I begin to worry about RSI. Go figure. Don't get me wrong, this apple mouse is genius and looks pretty as hell, but my right wrist feels tired after a full day's worth of work, so i'm thinking of switching. Anyone out there use a trackball? is this worse? should I get a super-ergonomic mouse instead? I've seen mouse-trackball combos but am not sold, they still elicit the same end-finger behaviour detrimental for RSI, right? I also have a wrist-rest mousepad, but couldn't find one suitable for my keyboard. I've even considered having a small touchscreen where the mousepad should go, no mouse (or alternatively, a usb trackpad). Just looking for ideas, is the trackball better than the mouse? /mp

  • Authorizing a computer to access a web application

    - by HackedByChinese
    I have a web application, and am tasked with adding secure sign-on to bolster security, akin to what Google has added to Google accounts. Use Case Essentially, when a user logs in, we want to detect if the user has previously authorized this computer. If the computer has not been authorized, the user is sent a one-time password (via email, SMS, or phone call) that they must enter, where the user may choose to remember this computer. In the web application, we will track authorized devices, allowing users to see when/where they logged in from that device last, and deauthorize any devices if they so choose. We require a solution that is very light touch (meaning, requiring no client-side software installation), and works with Safari, Chrome, Firefox, and IE 7+ (unfortunately). We will offer x509 security, which provides adequate security, but we still need a solution for customers that can't or won't use x509. My intention is to store authorization information using cookies (or, potentially, using local storage, degrading to flash cookies, and then normal cookies). At First Blush Track two separate values (local data or cookies): a hash representing a secure sign-on token, as well as a device token. Both values are driven (and recorded) by the web application, and dictated to the client. The SSO token is dependent on the device as well as a sequence number. This effectively allows devices to be deauthorized (all SSO tokens become invalid) and mitigates replay (not effectively, though, which is why I'm asking this question) through the use of a sequence number, and uses a nonce. Problem With this solution, it's possible for someone to just copy the SSO and device tokens and use in another request. While the sequence number will help me detect such an abuse and thus deauthorize the device, the detection and response can only happen after the valid device and malicious request both attempt access, which is ample time for damage to be done. I feel like using HMAC would be better. Track the device, the sequence, create a nonce, timestamp, and hash with a private key, then send the hash plus those values as plain text. Server does the same (in addition to validating the device and sequence) and compares. That seems much easier, and much more reliable.... assuming we can securely negotiate, exchange, and store private keys. Question So then, how can I securely negotiate a private key for authorized device, and then securely store that key? Is it more possible, at least, if I settle for storing the private key using local storage or flash cookies and just say it's "good enough"? Or, is there something I can do to my original draft to mitigate the vulnerability I describe?

  • Can I draw Qt objects directly to Win32 DC (Device Context)?

    - by Kevin
    I can draw Qt objects to an QImage and then draw the image to HDC or CDC. This may hurt our application's performance. It would be great if I can draw Qt objects directly to Win32 HDC or MFC CDC. I expect that there is a class, say QWin32Image for clear, then I can use it in this way: QWin32Image image(hdc, 100, 100, Format_ARGB32_Premultiplied); QPainter painter(&image); painter.drawText(....); Is it possible for my thought? Or is there a better way to do that?

    - by adopilot
    I have to handle TXT dat files which coming from one embed device, My problem is in that device always sending all captured data but I want to take only difrences between two sending and do calculation on them. After calculation I send it to SQL using bulkinsert function. I want to extract data which is different according to first file I got from device. Lats say that device first time device send data like this in some.dat (ASCII) file 0000199991 0000199321 0000132913 0000232318 0000312898 On second calls to get data from device it is going to return all again (previous and next captured records) something like this 0000199991 0000199321 0000132913 0000232318 0000312898 9992129990 8782999022 2323423456 But this time I do want only to calculate and pass trough data added after first insert. I am trying to make Win Forms app using C# and Visual Studio 2008

    Hi, I developed a simple application for iPAD. I want to test the app how it works on the device. I have paid developer licence, and i have added the device id and created the app id and i have downloaded the provisioning profile using both. The same way how we will build the app for iphone i have done for ipad. i have sent the provisioning profile and .ipa file to my friend to load on to the ipad device(same device which i have added in the developer.apple.com). when he tried to drag n drop the provisioning file on to the device from iTunes it is giving below error. "abc.mobileprovision" was not copied on to the iPAD, because it cannot be palyed on this iPAD I am not able to understand what the exact error is. Can anyone please let me know how to dump the applicatio on to the ipad device?

  • How to read LARGE Sqlite file to be copied into Android emulator, or device from assets folder?

    - by Peter SHINe ???
    I guess many people already read this article: Using your own SQLite database in Android applications: http://www.reigndesign.com/blog/using-your-own-sqlite-database-in-android-applications/comment-page-2/#comment-12368 However it's keep bringing IOException at while ((length = myInput.read(buffer))>0){ myOutput.write(buffer, 0, length); } I’am trying to use a large DB file. It’s as big as 8MB I built it using sqlite3 in Mac OS X, inserted UTF-8 encoded strings (for I am using Korean), added android_meta table with ko_KR as locale, as instructed above. However, When I debug, it keeps showing IOException at length=myInput.read(buffer) I suspect it’s caused by trying to read a big file. If not, I have no clue why. I tested the same code using much smaller text file, and it worked fine. Can anyone help me out on this? I’ve searched many places, but no place gave me the clear answer, or good solution. Good meaning efficient or easy. I will try use BufferedInput(Output)Stream, but if the simpler one cannot work, I don’t think this will work either. Can anyone explain the fundamental limits in file input/output in Android, and the right way around it, possibly? I will really appreciate anyone’s considerate answer. Thank you. WITH MORE DETAIL: private void copyDataBase() throws IOException{ //Open your local db as the input stream InputStream myInput = myContext.getAssets().open(DB_NAME); // Path to the just created empty db String outFileName = DB_PATH + DB_NAME; //Open the empty db as the output stream OutputStream myOutput = new FileOutputStream(outFileName); //transfer bytes from the inputfile to the outputfile byte[] buffer = new byte[1024]; int length; while ((length = myInput.read(buffer))>0){ myOutput.write(buffer, 0, length); } //Close the streams myOutput.flush(); myOutput.close(); myInput.close(); }

  • What do I have to do and how much does it cost to get a device driver for Windows Vista / 7 (32 and

    - by Jon Cage
    I've got some drivers which are basically LibUSB-Win32 with a new .inf file do describe product/vendor ids and strings which describe my hardware. This works fine for 32 bit windows, but 64 bit versions have problems; namely that Microsoft in their wisdom require all drivers to be digitally signed. So my questions are thus: Is there a version of the LibUSB-Win32 drivers which are already signed I could use? If there aren't already some signed ones I can canibalise, what exactly do I have to do to get my drivers signed. Do I need to get 64 and 32 bit versions signed separately and will this cost more? Is this a free alternative to getting them signed? Are there any other options I should consider besides requiring that my customers boot into test mode each time they start their machines (not an option I'd consider).

  • How to access device settings on a Sony Ericsson mobile phone?

    - by TheRHCP
    Edited on April 29th Hello everyone, I recently bought a Sony Ericsson mobile phone which embeds Symbian S60 and I would like to add a missing feature myself. In fact I cannot actually disable Internet connection in an easy way when roaming, which cost me a lot of money last time I moved away ... So I would like to develop a little application that would just replace the actual Internet configuration with a fake configuration to avoid auto-connections. So what I would like to know is how can I access programmatically to my phone settings? I believe that this is possible but I do not really have a clue where to start. I know that Sony Ericsson provides a SDK to run Java applications on its customised JVM but Symbian is also providing a SDK to develop applications for S60 devices in many languages. The real questions is which SDK will provide an API able to access phone settings. This is not well documented so I am asking this question with the hope that someone here already had experience with development for Sony Ericsson/Symbian devices. Thanks. EDIT: It seems that I was totally wrong concerning my phone. This not based on any Symbian OS at all. This is pure Sony Ericsson so the only solution would be to look if Sony Ericsson extended J2ME functionality in their own JVM. I am gonna investigate on this.

  • How do I utilize REST to post GPS data from an Android device into a Ruby on Rails application?

    - by joecan
    I am a student in the process a building an Android app that can post a GPS track into a Rails application. I would like to do things the "Rails" way and take advantage of the REST. My rails application basically has 3 models at this point: users, tracks, and points. A user has_many tracks and a track has_many points. A track also has a total distance. Points have a latitude and longitude. I have successfully been able to create an empty track with: curl -i -X POST -H 'Content-Type: application/xml' -d '<track><distance>100</distance></track>' http://localhost:3000/users/1/tracks Whoo hoo! That is pretty cool. I am really impressed that rails do this. Just to see what would happen I tried the following: curl -i -X POST -H 'Content-Type: application/xml -d '<track><distance>100</distance><points><point><lat>3</lat><lng>2</lng></point></points></track>' http://localhost:3000/users/1/tracks Fail! The server spits back: Processing TracksController#create (for 127.0.0.1 at 2010-04-14 00:03:25) [POST] Parameters: {"track"={"points"={"point"={"lng"="2", "lat"="3"}}, "distance"="100"}, "user_id"="1"} User Load (0.6ms) SELECT * FROM "users" WHERE ("users"."id" = 1) ActiveRecord::AssociationTypeMismatch (Point(#-620976268) expected, got Array(#-607740138)): app/controllers/tracks_controller.rb:47:in `create' It seems my tracks_controller doesn't like or understand what it's getting from the params object in my tracks_controller.rb: def create @track = @user.tracks.build(params[:track]) My xml might be wrong, but at least Rails seems to be expecting a Point from it. Is there anyway I can fix TracksController.create so that it will be able to parse xml of a track with nested multiple points? Or is there another way I should be doing this entirely?

  • Only some windows shell commands work via ruby?

    - by Sanarothe
    Hi. I'm trying to use a script to control my power options since XP doesn't give you an intuitive way to change CPU Frequency options. Here's my script so far: meh = `cmd.exe /C POWERCFG.EXE /QUERY Portable/Laptop` puts "" puts meh case input when 1 then system('cmd.exe /C POWERCFG.EXE /CHANGE Portable/Laptop /processor-throttle-ac NONE') when 2 then system('cmd.exe /C POWERCFG.EXE /CHANGE Portable/Laptop /processor-throttle-ac ADAPTIVE') when 3 then `cmd.exe /C POWERCFG.EXE /CHANGE Portable/Laptop /processor-throttle-ac CONSTANT` end The problem is that the changes simply don't take place. If I run the same commands directly into a cmd.exe prompt, they work. It's very strange, but nothing works after the initial powercfg query. I feel like I'm missing something incredibly obvious. How can I get the above script to run correctly?

    I have a modal pop up function on my website, but i don't want this to run if the browser is smaller than 480px. I have found that if I put an if statement such as: if (window.innerWidth && window.innerWidth > 480) { run function() } Then it should run only if the browsers innerWidth is 480. However its not working and I think its because I have page scaling on this website. Can any one help me with a conditional statement if page scaling is on? Thanks.
