Citeren Arnaud Quette <[email protected]>: > Alex, be sure to also address blazer_usb since it's the long run approach.
It will already work with this UPS. The problem is in the way how the phoenix subdriver in megatec_usb deals with reading data from the UPS. Currently, it reads data until it receives a timeout or the supplied buffer is full. This will work for most devices, but not all. The proper way to do this (implemented in blazer_usb) is to read until either - a read for an eight byte chunk of data times out (which is a timeout error) - the number of requested characters is read - a '\r' character is read (characters following this should be discarded) Also note that currently reading partial data (less data was read than requested) is broken in megatec_usb. Especially Mustek devices often seem to return 7 characters, when we requested 8.
