• Booted the CERN SL Kernel 2.6.33.9-rt31.79.el6rt.x86_64 dev system
• Plugged the USB device into the CPU directly
• Kernel recognized the device as:

  usb 2-1.7: new full speed USB device using ehci_hcd and address 3
  usb 2-1.7: New USB device found, idVendor=09db, idProduct=00bc
  usb 2-1.7: New USB device strings: Mfr=1, Product=2, SerialNumber=3
  usb 2-1.7: Product: USB-TEMP-AI
  usb 2-1.7: Manufacturer: MCC
  usb 2-1.7: SerialNumber: 00107479
  generic-usb 0003:09DB:00BC.0003: hiddev96,hidraw2: USB HID v1.01 Device [MCC USB-TEMP-AI] on usb-0000:00:1d.0-1.7/input0

For generic programming, we are going to want to use the UL library.

Looking in this FTP site for code: ftp://lx10.tx.ncsu.edu/pub/Linux/drivers/USB/

Requires libusb, found an online page suggesting check this:

rpm -qa | grep -i libusb
libusb1-1.0.9-0.6.rc1.el6.x86_64
libusb-0.1.12-23.el6.x86_64

1. Installed these packages

   sudo yum install libusb-devel libudev-devel libusb1 libusb1-devel 

2. Grabbed this

   mkdir ~/code
   cd ~/code
   git clone git://github.com/signal11/hidapi.git

3. Compile and install

   cd ~/code/hidapi/
   ./bootstrap
   ./configure
   make
   sudo make install

4. Install the udev rules for the system
   1. Now located in the MCCLinuxDrivers directory
      1. Download the rules from their site <code> cd /tmp wget https://raw.githubusercontent.com/wjasper/Linux_Drivers/master/60-mcc.rules wget https://raw.githubusercontent.com/wjasper/Linux_Drivers/master/61-mcc.rules </code>
   2. Copy the files into the udev configuration

      sudo cp ~/src/MCCLinuxDrivers/6*-mcc.rules /etc/udev/rules.d/
      sudo chmod 644 /etc/udev/rules.d/6*-mcc.rules
      sudo chown root:root /etc/udev/rules.d/6*-mcc.rules

   3. Restart udev

      sudo /sbin/udevadm control --reload
      sudo /sbin/udevadm control --reload-rules

1. Download code <code> cd ~/code git clone https://github.com/wjasper/Linux_Drivers.git </code>
2. Build and install

   cd ~/src/MCCLinuxDrivers/USB/mcc-libusb
   make
   sudo make install
   sudo ldconfig

3. Had to add /usr/local/lib to an ldconfig script
   1. Modify /etc/ld.so.conf.d/lvisf.conf

      sudo nano /etc/ld.so.conf.d/lvisf.conf

   2. Append this line to the file if it isn't already there into /etc/ld.so.conf.d/lvisf.conf

      /usr/local/lib

   3. It looks like this for me now — David Lloyd Rabine 2016/07/28 15:07

      /home/lvis/src/spectrum/shared/linux/pc64/lib
      /home/lvis/src/MIC3753/linux_driver_source_3.2.7.0_64bit/libs
      /opt/lvisf/src/lvisF/build/lib/msgService
      /opt/lvisf/src/lvisF/build/lib/shmem
      /usr/local/lib

4. Now run ldconfig to get the library to be in our path

   sudo ldconfig

1. To where the code is installed at the moment

   cd /home/lvis/src/MCCLinuxDrivers/USB/mcc-libusb

2. Run the test program

   ./test-usb-temp-ai

3. Appears to work!

   [lvis@lvisf-centos65 mcc-libusb]$ ./test-usb-temp-ai
   USB TEMP-AI is found.
