these lines here tell us that the driver cannot find the UPS and by 
matter the consequence, the driver does not start

this  error is normal and due to the previously reported problem ( 
driver not started )

that's quite old, it reached end of life almost 2 years ago. I suggest 
using a newer OS if possible.

777 is never a good idea. never ever, except for limited testing 
environments. correct mode for all these files is 640

Check in the system logs ( |/var/log/messages* ||) if a /dev/*USB* gets 
created by the usb-to-serial interface. You should see something similar to
|

|/var/log/messages.1:Jan 12 02:17:18 pi kernel: [ 20.554591] usbserial: 
USB Serial support registered for generic
/var/log/messages.1:Jan 12 02:17:18 pi kernel: [   20.671305] usbserial: 
USB Serial support registered for pl2303
/var/log/messages.1:Jan 12 02:17:18 pi kernel: [   20.729145] usb 1-1.2: 
pl2303 converter now attached to ttyUSB0

|

|If there is no such message, try disconnecting and reconnecting the 
adapter. If still not, you have a problem with the drivers for the 
adapter, the kernel does not create the interface needed to access it 
and you will have too resolve this issue first.|

|If /dev/ttyUSB0 or similar exists, you have permission problems - 
blazer_usb is not allowed to access it|
