• Install usblib package - Ubuntu

  - by Tom celic

  I need the package libusb for another package I am installing. I tried the following which seemed to install the package, sudo apt-get install libusb-dev but when I try to install the other package I get, configure: error: Package requirements (libusb-1.0 >= 0.9.1) were not met: No package 'libusb-1.0' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables LIBUSB_CFLAGS and LIBUSB_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. When I run the command dpkg -L libusb-dev, I get: /. /usr /usr/bin /usr/bin/libusb-config /usr/include /usr/include/usb.h /usr/lib /usr/lib/libusb.a /usr/lib/libusb.la /usr/lib/pkgconfig /usr/lib/pkgconfig/libusb.pc /usr/share /usr/share/doc /usr/share/doc/libusb-dev /usr/share/doc/libusb-dev/html /usr/share/doc/libusb-dev/html/index.html /usr/share/doc/libusb-dev/html/preface.html /usr/share/doc/libusb-dev/html/intro.html /usr/share/doc/libusb-dev/html/intro-overview.html /usr/share/doc/libusb-dev/html/intro-support.html /usr/share/doc/libusb-dev/html/api.html /usr/share/doc/libusb-dev/html/api-device-interfaces.html /usr/share/doc/libusb-dev/html/api-timeouts.html /usr/share/doc/libusb-dev/html/api-types.html /usr/share/doc/libusb-dev/html/api-synchronous.html /usr/share/doc/libusb-dev/html/api-return-values.html /usr/share/doc/libusb-dev/html/functions.html /usr/share/doc/libusb-dev/html/ref.core.html /usr/share/doc/libusb-dev/html/function.usbinit.html /usr/share/doc/libusb-dev/html/function.usbfindbusses.html /usr/share/doc/libusb-dev/html/function.usbfinddevices.html /usr/share/doc/libusb-dev/html/function.usbgetbusses.html /usr/share/doc/libusb-dev/html/ref.deviceops.html /usr/share/doc/libusb-dev/html/function.usbopen.html /usr/share/doc/libusb-dev/html/function.usbclose.html /usr/share/doc/libusb-dev/html/function.usbsetconfiguration.html /usr/share/doc/libusb-dev/html/function.usbsetaltinterface.html /usr/share/doc/libusb-dev/html/function.usbresetep.html /usr/share/doc/libusb-dev/html/function.usbclearhalt.html /usr/share/doc/libusb-dev/html/function.usbreset.html /usr/share/doc/libusb-dev/html/function.usbclaiminterface.html /usr/share/doc/libusb-dev/html/function.usbreleaseinterface.html /usr/share/doc/libusb-dev/html/ref.control.html /usr/share/doc/libusb-dev/html/function.usbcontrolmsg.html /usr/share/doc/libusb-dev/html/function.usbgetstring.html /usr/share/doc/libusb-dev/html/function.usbgetstringsimple.html /usr/share/doc/libusb-dev/html/function.usbgetdescriptor.html /usr/share/doc/libusb-dev/html/function.usbgetdescriptorbyendpoint.html /usr/share/doc/libusb-dev/html/ref.bulk.html /usr/share/doc/libusb-dev/html/function.usbbulkwrite.html /usr/share/doc/libusb-dev/html/function.usbbulkread.html /usr/share/doc/libusb-dev/html/ref.interrupt.html /usr/share/doc/libusb-dev/html/function.usbinterruptwrite.html /usr/share/doc/libusb-dev/html/function.usbinterruptread.html /usr/share/doc/libusb-dev/html/ref.nonportable.html /usr/share/doc/libusb-dev/html/function.usbgetdrivernp.html /usr/share/doc/libusb-dev/html/function.usbdetachkerneldrivernp.html /usr/share/doc/libusb-dev/html/examples.html /usr/share/doc/libusb-dev/html/examples-code.html /usr/share/doc/libusb-dev/html/examples-tests.html /usr/share/doc/libusb-dev/html/examples-other.html /usr/share/doc/libusb-dev/copyright /usr/share/doc-base /usr/share/doc-base/libusb-dev /usr/share/man /usr/share/man/man1 /usr/share/man/man1/libusb-config.1.gz /usr/lib/libusb.so /usr/share/doc/libusb-dev/changelog.Debian.gz Any ideas??

• Python libusb pyusb "mach-o, but wrong architecture"

  - by Jon

  I am having some trouble with the pyusb module. I have narrowed down the problem to a single line, and have created a small example script to replicate the error. #!/usr/bin/env python """ This module was created to isolate the problem in the pyusb package. Operating system: Mac OS 10.6.3 Python Version: 2.6.4 libusb 1.0.8 has been successfully installed using: sudo port install libusb I have also tried modifying /opt/local/etc/macports/macports.conf to force the i386 architecture instead of x86_64.

• How can I remove LibUSB on Windows 7?

  - by Cokegod

  I've installed LibUSB, a software that modifies your USB driver so that programs can access it easily. I didn't know that in Windows 7 you have to run it in compatibility mode for Windows XP, so now my Windows 7 can't access any USB port (including keyboard and mouse). Now I can't access my computer at all, and I don't have any PS2 connection in my computer. I tried to run it in Safe Mode but it didn't change anything. I tried to run a system restore from before the installation of LibUSB, but all the restore points give me an error: "The instruction at 0x73888f18 referenced memory at 0x00000004. The memory could not be read." I also tried to run Hiren's Boot CD and remove all the files associated with LibUSB, but that didn't change anything. So how can I remove LibUSB and access my computer again without formatting my hard drive? (I have important things on it)

• Strange macro declaration in C

  - by Andrey Atapin

  Exploring libusb-1.0.9 source code, I have found such line (./os/poll_windows.c:78): #define CHECK_INIT_POLLING do {if(!is_polling_set) init_polling();} while(0) As for me this is the same like: #define CHECK_INIT_POLLING if(!is_polling_set) init_polling(); Is there any reason to loop that expression? UPDATE: I couldn't still realize what'd be wrong after the answers, and the following example helped: #include <stdio.h> #define TEST if(test) foo(); #define TEST_DO do { if(test) foo(); } while(0) int test = 1; void foo() { printf("%s", "Foo called"); } int main(int argc, char** argv) { if(argc > 1) TEST_DO; /* LINE 12 */ else printf("%s", "skipping..."); return 0; } If you put TEST at line 12, a compiler will give an error "error: ‘else’ without a previous ‘if’". Hope, this will help someone.

• Is there an alternative to libusb-win32 for 64bit windows?

  - by Jon Cage

  I've been developing some software which uses the libusb-win32 library to interact with some USB hardware I've been developing. Now I'm trying to run the same software on windows 64 but the drivers don't seem to work (understandably). Are there any alternatives for 64 bit Windows I've overlooked?

• 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).

• Map /dev/bus/usb node to /sys node on Linux

  - by Cody Brocious

  I'm using libusb to find and access a USB device, but once I get the information I need from there, I need to map it to a /sys node. This could be to the actual USB bus it's on, the /sys/bus/usb-serial node (which is where I'm going to get eventually), or effectively anywhere else since I can walk the tree from there. I can get to a /dev/bus/usb node easily enough, but I'm a bit lost from there. What would be the best route to perform this mapping?

• Installing unsigned x64 driver to work with libusbdotnet

  - by user216194

  Hi all- I am currently in a Windows 7 dev. environment working to get a device to initialize with libusbdotnet. The device (a USB mass storage device) connects and runs using the default USB-MASS Storage driver for Windows. I want to replace this driver with the one created by the .INF Wizard in libusbdotnet. The operating system is a 64-bit, and by default the INF Wizard produces this driver, but I am unable to selected it because it is "unsigned" I believed, when I go to "Pick from a list of drivers" and point to the directory where the newly created device drivers are. I have enabled "TEST MODE" using DESO but I'm still unable to select this file. Anyone familiar with libusbdotnet, or directing devices to work with a specific driver that is unsigned in Window (do I need the .inf file? or the .sys???) do you have any advice about where I'm going wrong? Thanks!

• Python, SWIG and other strange things

  - by wanderameise

  hey, I have a firmware for an USB module I can already control by visual C. Now I want to port this to python. for this I need the octopus library which is written in c. I found a file called octopus_wrap which was created by SWIG! then I found a makefile which says: python2.5: swig -python -outdir ./ ../octopus.i gcc -fPIC -c ../../liboctopus/src/octopus.c gcc -fPIC -c ../octopus_wrap.c -I /usr/include/python2.5 gcc -fPIC -shared octopus_wrap.o octopus.o /usr/lib/libusb.so -o _octopus.so python2.4: swig -python -outdir ./ ../octopus.i gcc -fPIC -c ../../liboctopus/src/octopus.c gcc -fPIC -c ../octopus_wrap.c -I /usr/include/python2.4 gcc -fPIC -shared octopus_wrap.o octopus.o /usr/lib/libusb.so -o _octopus.so win: gcc -fPIC -c ../../liboctopus/src/octopus.c -I /c/Programme/libusb-win32-device-bin-0.1.10.1/include gcc -fPIC -c octopus_wrap.c -I /c/Python25/libs -lpython25 -I/c/Python25/include -I /c/Programme/libusb-win32-device-bin-0.1.10.1/include gcc -fPIC -shared *.o -o _octopus.pyd -L/c/Python25/libs -lpython25 -lusb -L/c/Programme/libusb-win32-device-bin-0.1.10.1/lib/gcc clean: rm -f octopus* _octopus* install_python2.4: cp _octopus.so /usr/local/lib/python2.4/site-packages/ cp octopus.py /usr/local/lib/python2.4/site-packages/ install_python2.5: cp _octopus.so /usr/local/lib/python2.5/site-packages/ cp octopus.py /usr/local/lib/python2.5/site-packages/ I dont know how to handle this but as far as I can see octopus.py and _octopus.so are the resulting output files which are relevant to python right? luckily someone already did that and so I put those 2 files to my "python26/lib" folder (hope it doesnt matter if it´s python 2.5 or 2.6?!) So when working with the USB device the octopus.py is the library to work with! Importing this file makes several problems: >>> Traceback (most recent call last): File "C:\Users\ameise\My Dropbox\µC\AVR\OCTOPUS\octopususb-0.5\demos\python \blink_status.py", line 8, in <module> from octopus import * File "C:\Python26\lib\octopus.py", line 7, in <module> import _octopus ImportError: DLL load failed: module not found. and here´s the related line 7 : import _octopus So there´s a problem considering the .so file! What could be my next step? I know that´s a lot of confusing stuff but I hope anyone of you could bring some light in my mind! thy in advance

• Install usb device without manager prompt

  - by Pat

  We have a usb device and the drivers (.inf, libusb.dll, libusb.sys) and can install it using Windows' Device Installation Wizard (by pointing to the .inf file). However, we need to install the drivers without using the wizard (passively, so the user doesn't need to do anything). Does anyone know how this can be achieved?

• Getting MTP to work with a Galaxy tab 2 7.0?

  - by Wouter

  I'm trying to get MTP with the galaxy tab 2 7.0 working on my ubuntu installation. Such that I can access the files. I tried to do what is described here: http://www.omgubuntu.co.uk/2011/12/how-to-connect-your-android-ice-cream-sandwich-phone-to-ubuntu-for-file-access I however fail at executing one of the following commands mtp-detect | grep idVendor mtp-detect | grep idProduct This fails [20:42|0] $ mtp-detect | grep idVender Device 0 (VID=04e8 and PID=6860) is a Samsung GT-P7310/P7510/N7000/I9100/Galaxy Tab 7.7/10.1/S2/Nexus/Note.

PTP_ERROR_IO: failed to open session, trying again after resetting USB interface LIBMTP libusb: Attempt to reset device LIBMTP PANIC: failed to open session on second attempt Unable to open raw device 0 Now my guess was was that the idVender is the same as the VID (04e8) and the idProduct is the same as PID (6860) Now I continued to work with those values and completed the tutorial. When finished I tried android-connect This returned fuse: bad mount point `/media/GalaxyTab': Transport endpoint is not connected Does anybody have a clue what to do? Also I want to note that when I connect my GalaxyTab 2 7.0 that I still get a pop-up of ubuntu that a device was connected. I also can still see the mapstructure, the problem however is is that all the folders have 0 bytes and do not have any subfolders. I can only see the folders in the root. ps. I also checked a similar question and tried what is described in this answer http://askubuntu.com/a/88630/27480

• How do you get the mount point/disk drive of a USB stick in cross-platform C++ or C?

  - by darkadept

  I'm trying to get the mount point(linux/osx) or disk drive (windows) of a specific USB mass storage device. I can use libusb to determine if the correct device is inserted but how do I determine where it is mounted? I'm using C++ but I assume C code would work just as well. Cross-platform code would be preferable.

• All Webcams (integrated or otherwise) have stopped working

  - by cgoddard

  Recently, like in the last few months (incidentally, I didn't notice it at first, but I think it might have coincided with the installation of libusb) all webcams have stopped working on my laptop. But, its not a driver error or anything like that, the webcam claims it is working, but when I try to use it in skype, it tells me that it thinks another program is using my webcam. However, I have tried going through every program and closing it until system crash, but it never becomes available. But the light on the side of the inbuilt webcam doesn't come on. And when I added a second webcam, it became available to the system, installed fine, return error 0 on the devices manager, and when I tried to use it, claimed it was in use. How can I find out what might have gone wrong to be causing the system to think that the webcams are constantly in use?

• TotalPhase Aardvark driver's GPL license

  - by Philip

  I'm using an SPI host adapter for a project. The Aardvark from TotalPhase. And I did something crazy, I read that EULA license that everyone just clicks through. The driver installation license includes these bits: This driver installer package also includes a WIN32 driver that is entirely based on the libusb-win32 project (release 0.1.10.1). ... LICENSE: The software in this package is distributed under the following licenses: Driver: GNU General Public License (GPL) Library, Test Files: GNU Lesser General Public License (LGPL) Now, my understanding of of the GPL is that it's sticky and viral. If you include software then the whole project has to be released under the GPL (if you distribute it, you can do whatever you want with in-house projects). If the driver was like the library, and was licensed under the LGPL, it could be used by my closed source proprietary project, as long as it's source and license was passed along with it. But it's not, it's pure GPL. If I include this driver in my project and distribute it, am I required to release my project under the GPL?

• Problem with SANE and CardScan

  - by TiuTalk

  I have a CardScan 60 II device and installed SANE in my Ubuntu 10.10 laptop. The problem is I can't make scanimage find the device.

• File doesn't exist when trying to change permissions following the avasys image scan manual

  - by Howard Graham

  I was finally able to connect to avasys.jp and downloaded and installed iscan_2.28.1-3.ltdl7_amd64.deb iscan-data_1.13.0-1_all.deb. The programs appeared to install correctly. I then ran sane-find-scanner and got back: found USB scanner (vendor=0x04b8, product=0x012d) at libusb:001:003 I then ran lsusb and got back: Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 003: ID 04b8:012d Seiko Epson Corp.

Optical Mouse the avasys image scan manual instructed me to run chmod 0666 /proc/bus/usb/001/003 which returned chmod: cannot access `/proc/bus/usb/001/003': No such file or directory In 12.04, no such directory exists. 12.04 appears to deal with USB in another way. What must I do to get the usb port 001/003 recognized by xsane and sane as the port where the scanner can be located? What must I do to continue installing the scanner?

• WinUSB application or User-Mode Driver as a filter driver for USB Analysis/Sniffer/Trending

  - by Robert

  A question to maybe some who have worked extensively with WinUSB APIs or use mode USB drivers - Does anyone know if the WinUSB API or a user mode driver can be used as a passive observer of USB connections, capturing notification of interrupts, control requests, data transfers...etc without interfering with other applications (such as iTunes) which would obviously require concurrent access to the device at the same time my application is monitoring the connection and displaying data on it? Or do you pretty much have to write a kernel-mode filter driver and inject yourself in the USB stack in order to make that happen? In the past, there have been a few credible options (libusb-win32 and usbsnoop to be specific) though both are built around the old DDK, not the Windows Driver Foundation, and are not really supported on a regular basis any more. I'm hesitant to build something significant around them, as a result.
