Hmmm, OK, I misspoke, it seems. 16-byte CDBs do not get to our device at all. We are trying to figure out why. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Richard Sharpe Sent: Wednesday, October 03, 2007 9:07 AM To: [email protected] Subject: Re: [linux-usb-devel] Does Linux support more than 2TB on a USBattached device? -----Original Message----- From: Stephen J.

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.
