Could be a cable problem, too.</pre>

Also, devices that talk to blazer_usb are basically serial UPSes with a USB-to-serial converter. The increased CPU usage is not surprising, since the host now has to poll the USB-to-serial converter (rather than the UART interrupting the CPU when data is ready). Do you have any profiling data to show how much more CPU time is being used?

I don't have any profiling data, I just noticed that blazer_usb is
ever first in 'top' list, with older blazer driver it was at the end
of the 'top' list, now it uses always 0,3% to 1,7% of CPU with
poolinterval at 2 seconds.<br>
<br>
My CPU is not so powerful but anyway it is a good diference and so I
noted it..<br>
