If I didn't overlook anything Zydas hardcoded this bitmask in it's latest driver. (presumably to solve problems with devices that don't set it properly) It used to be retrieved from EEPROM. If I remember correctly each bit represents a channel and the bitmask is split up as follows: 000107ff => 0001 (default channel) 07ff (available/allowed channels) The first log entry represents the retrieved (but now hardcoded) allowed channel mask. The second entry has the default channel added. > What does “Region: 48” mean? Is 48 intended to be a region code?

If I remember correctly it stand for ETSI (most of Europe) / Taiwan region. ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
