Programming :: Learning LibUSB From C Code
Oct 1, 2010I'm trying to learn how to use USB from c code. Rather trying kernel stuff I thought I'd (after some searching ) use libusb. So I searched for documentation, unfortunately I came across two sets of documents each with it's own API?
[URL] and [URL]
For example one inits with libusb_init (libusb_context **context) the other uses void usb_init(void); I'm using libusb rather than kernel programming as I'd like to compile the code for windows as well as linux.

Programming :: Where To Get GTK Tutorial?
May 19, 2010I already figured out the basics of gtk2-perl, but i can't find a good tutorial for things like lists, scrolling viewports, drag n' drop, etc.
I guess any programming language is OK because it shouldn't be hard to translate it into Perl.

Jul 30, 2011I'm looking for javascript tutorials or books that meets the following criteria:
1. Very thorough: Starts with the most fundamental concepts and progresses logically from basic to advanced concepts, without skipping over important ideas for the sake of expediency.
2. Lots of small practice exercises that parallel the concepts and syntax being learned.
I've looked at a lot of tutorials, but they all tend to be lacking in one of these areas or the other.

View 3 Replies View RelatedOpenSUSE :: Piklab, PICKit 2 And Libusb Under 11.2?
Jul 15, 2010I am running 11.2 64 bit on a Dell Vostro machine. I am unable to get piklab to connect to a PICKit 2 over USB. I have created a file /etc/udev/rules.d/26-microchip.rules which contains the line:
ATTR{idVendor}=="04d8", ATTR{idProduct}=="0033", OWNER:="root", GROUP:="users",MODE:="0660"
This gives a node /dev/bus/usb/006/002 with attributes crw-rw---- owner root group user. The device is rear/write to any member of the "users" group.In piklab the dialogue "Configure Piklab" reached through the menu Programmer->Settings... on the Preogrammer Selection the Port Selection tab displays USB Connection:Error.After much research I find that there may be problems with the libusb library under 11.2 so I try to see what is returned by lsusb. I enter the command:
sudo lsusb -v -s 006:002
this returns:
Bus 006 Device 002: ID 04d8:0033 Microchip Technology, Inc.
Device Descriptor:
bLength 18
bDescriptorType 1
bcdUSB 2.00
bDeviceClass 0 (Defined at Interface level)
[code]....
This shows that the udev mechanism appears to be finding the device and all the data is being collected but the last line looks ominous.
What does "cannot read device status, Broken pipe (32)" mean and where does it come from? Is this the cause of the USB connection error?
Ubuntu Installation :: How To Install The Libusb

View 3 Replies View RelatedUbuntu :: LibUSB - How To Check If It Is Installed
Jun 1, 2011I'm trying to install libusb. I've downloaded a file from [URL]. I've unzipped the file; the folder's on my desktop. I've tried to install this, but I'm not sure how. Under installation it says: See the file 'INSTALL'. There are a few files that start with this term: INSTALL.libusb, INSTALL.libusb.in and install-sh. The first two appear to be the same, while the latter appears to be some sort of program.
When I double click it, I get a few options, including "run". I assumed this was the correct way to install the program, but when I hit run, nothing happens. I've displayed this file, but this gives me no additional information. I've tried running it in terminal: nothing. Maybe it has installed, and I just don't know it. How would I even check if it's installed? (I'm only installing libusb because I need it for something else).

Ubuntu :: LibUSB Not Available To Sane Find Scanner
Apr 21, 2011I too have what looks like the same problem. I too have read all the relevant man pages and other relevant sites:

CanoScan LiDE 110 (the printer I've just bought) has "complete" support apparently.
Followed directions here: [URL]

Another story of purchasing a "complete"ly supported scanner. [URL]
The solution? Use windows xp in a vm.
I don't think much of that sort of solution. As a temporary work around... ok. I'm running debian lenny.

Dec 13, 2010I am developing a program that uses libusb-1.0 on a FC14 x64 system. I solved the compile and link issues, but I now have a problem with user privileges when I try to get device handles.

Slackware :: Error - Libusb Couldn't Open USB Device /dev/bus/usb/001/001: Permission Denied
Mar 24, 2011Hello,
this error spams about 100 times, then the scanner does indeed work. So I'm not completely broken, but the error messages are of concern, and it slows down the process of scanning for the time it takes to do the messages.
Error in console:
libusb couldn't open USB device /dev/bus/usb/001/001: Permission denied. libusb requires write access to USB device nodes.
my sript runs:
scanimage
--device $MODEL
--resolution=$RESOLUTION

my groups:
uid=1000(fogie) gid=100(users) groups=100(users),7(lp),11(floppy),12(mail),15(man),17(audio),18(video),19(cdrom),20(games),21(sloca te),83(plugdev),84(power),86(netdev),93(scanner)
Even a simple:
