[edit] Linux errors

1. If you get this error while trying to run flasher-3.5
   

   ./flasher-3.5: error while loading shared libraries: libusb-0.1.so.4: cannot open shared object file: No such file or directory

   you are probably on 64 bit and you need to install a libusb compatibility package. For example, on openSUSE 11.4 you just run
   

   zypper in libusb-0_1-4-32bit

   
   On a debian based system you can download and install the 32-bit version in a separate location (don't install it on your system itself -- note: installing libusb0.1-4 from repos on ubuntu 12.10-amd64 worked fine for one user)
   First download the libusb-0.1-4_0.1.12-13_i386.deb library (google is your friend) and then:
   

   dpkg-deb -c libusb-0.1-4_0.1.12-13_i386.deb

   sudo dpkg -x libusb-0.1-4_0.1.12-13_i386.deb libusb-0.1-4_0.1.12-13_i386

   sudo mv libusb-0.1-4_0.1.12-13_i386/lib/* /lib32

   cd /usr/lib32

   sudo ln -s /lib32/libusb-0.1.so.4

   
   Now Set the library path (as su):

   sudo su

   export LD_LIBRARY_PATH=/usr/lib32/:"$LD_LIBRARY_PATH"

   Now you can run the flasher application (as su)
   
2. basically all recent linux distros come with kernel module cdc_phonet. The problem is that the kernel module cdc_phonet that is automatically loaded and that disrupts the connection from flasher via USB to device. The solution is to temporarily (or even permanently, since it's a largely useless module) blacklist it, until you are done flashing. On openSUSE this can be done by creating a file like this:
   

   echo "blacklist cdc_phonet" >/etc/modprobe.d/00-blacklist-cdcphonet.conf

   When you finish flashing, remove the file 00-blacklist-cdcphonet.conf to revert back to normal - or just keep it this way, you probably won't miss cdc_phonet ever.
   
   

There are other, probably timing, reasons causing occasional "unable to enumerate USB". Immediately issue the flasher command again, up-arrow usually helps fetching last command to re-issue it.
