Thank you for that sage piece of advice. We already use GPT on our devices under Vista and Mac OS X. We have tracked down the problem. The USB Mass Storage layer in Linux does not support 16-byte CDBs, it seems. They get stamped with a length of 12 and are sent as short commands over USB, which we were issuing an ABORT to. We have fixed that by the simple expedient of handling short READ CAPACITY(16) requests in our device. However, READ(16) and WRITE(16) requests are a problem :-) ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
