I am trying to programming on leJOS and I need to some base on prerequisite steps. If Someone know could tell me how to install libusb on Ubuntu. And how can I check currently version or update or upgrade?

I guess I should have checked this before removing for real as it blew away my desktop, boot kernel, etc. Time now to re-install packages.

I'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).
I too have what looks like the same problem. I too have read all the relevant man pages and other relevant sites:
Supported devices [URL]
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.

View 3 Replies View RelatedI 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:

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?
I got Fedora core release 3
kernel 2.6.9-.667
I would like to know which command I have to use to see the libusb installed. I used this:
yum list installed | grep usb
but no output.
I am unable to understand libusb.
View 2 Replies View RelatedI'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.
I run a program (findknxusb) to scan for devices on USB, but the device is not found.
The debugging level for libusb is on:
$ ./findknxusb
Possible addresses for KNX USB devices:
libusb_set_debug...
libusb: setting debugging level to 1 (on)
libusb_init...

I'm having a weird problem with libusb-1.0. I have a fresh install of Fedora 11. I'm trying to control a USB HID device (own development) and I want to offer Linux support via libusb. Writing to the device is not a problem and works without any problem. The problems starts when I want to read from the device. Under Windows everything works without a problem.
Via lsusb -v I get this information:

I have an application that reads data from a medical device connected using usb.
I am writing the driver for this device since it is a vendor specific device.
I am using libusb v0.1 API and get notification to the application when the device is connected/disconnected.
I am using Linux Ubuntu with kernel 2.6.*
I've built a piece of hardware that communicates using usb. I was wondering could I make a libusb based program run on it's own without gcc/ libusb

I 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. The problem appears to be in the mounting of the usbfs. Is the an accepted fix to giving users read/write privileges for all usb devices?

I've been using this scanner on various suse builds all the way back to version 8. This week I installed OpenSuse on a brand new computer and when I run xsane, I receive these messages.
[Code]....
The scanner will scan for a few seconds and then the entire system freezes up.
Hello,
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:

Even a simple:

Since installing F11, my Canon LIDE 50 scanner refuses to work. xsane 0.996 produces an error message: Failed to start scanner: Error during device I/O.
sane-find-scanner says it is there: found USB scanner (vendor=0x04a9 [Canon], product=0x2213 [CanoScan], chip=GL841?) at libusb:001:006 But scanimage -L claims: No scanners were identified.except once when it admitted: device `genesys:libusb:001:006' is a Canon LiDE 35/40/50 flatbed scanner
I reluctantly tested the scanner on a Windoze machine and it works perfectly. And it worked perfectly under F10.

CUPS is showing that the "user" is my XP login name so I added that user to Linux and even added that account to the "lp" group and still get the above errors.
I have an apparently stable installation of Xubuntu that I've hand-tweaked in a few ways. I'd like to be able to reinstall this system verbatim on this machine should a disk crash happen, etc.Is there a "standard" method to create an install and/or total-backup CD that would be an instantiation of the currently-installed-and-modified system?
View 1 Replies View RelatedI am installing Ubuntu Server 10.10 on and old Dell Laptop. The network connection is an Xircom PCMCIA card.During install, the computer sees and interacts via the network just fine. For example, I can ping the gateway. Also, the command "lspcmcia" works and show the Xircom card.When I reboot, however, there is no network access, and the "lspcmcia" command is not there. When I try "lspcmcia" the OS helpfully tells me that I can "apt-get" pcmciautils, but, without network access, that fails.I tried adding the install cdrom to apt using "apt-cdrom" and then tried to "apt-get" pcmciautils and it got further, installing some dependencies, but acted like it still was unable to locate the pcmciautils package.

View 8 Replies View RelatedWhat is the easiest and/or safest way to migrate my Wubi 10.04 install to a full install? Currently, my Dell XPS M1530 is currently dual-booting Ubuntu 10.04 LTS and Windows Vista Home Premium, and I've decided after using Windows a total of around 4 hours over the past 6 months that I can probably let it go. So, I don't need Windows anymore and I believe I'm ready for a full install of Ubuntu. Though, I probably will wait for 11.04 to come out first.
A few ways I've thought of already are: 1) Find an external hard drive to put the Wubi files on. 2) Upload files to an storage website. 3) Temporarily put the Wubi files onto another computer (Windows). All these meaning I would then wipe my harddrive and install Ubuntu from a CD. And by "files", I mean Documents, Pictures, Downloads, etc.
EDIT: deleting all my applications, because OpenOffice.org won't reinstall on my computer due to dependency issues while attempting to install LibreOffice. So a fresh install would be nice.
I have been running ONLY linux (ubuntu) on my computer for years now. However, a friend sucked me back into the world of MMO's (angry fist @ RIFT). So, I decided to pick up a new disc, slap windows 7 on it and now want to dual boot.Basically I had to do some disc juggling to get windows to play nice. So my windows drive is now first, then my Ubuntu drive second.Its been a while so I'm wondering how involved / what would be the steps to get grub2 to chainload into windows7 (in my head I want to say I'm going to boot into the live cd, mount the windows disc and reinstall the loader to the windows drive since its the first disc in the chain?)
