MSPFlasher on linux

Hi All,

I have a serious problem with the MSPFlasher program on Linux. I have used successfully the program version 1.3.10 over a long time. I had to upgrade to 1.3.20. With this version a firmware upgrade was needed. I got the following error:

* -----/|-------------------------------------------------------------------- *

After this the flasher was unuseable and further tries did not work:

* -----/|-------------------------------------------------------------------- *
*     / |__                                                                   *
*    /_   /   MSP Flasher v1.3.20                                             *

# Exit: 49
# ERROR: MSP-FET / eZ-FET recovery failed
*
* ----------------------------------------------------------------------------

* ----------------------------------------------------------------------------
*/
Even with a new device I got the same errors. Now I have 2 not working flasher in my office. The serial number of the old flasher starts with 14... the nwe one starts with 19...

Any idea?
