I was looking at using the generic usb-serial driver as a debug console, and so I tried a simple loopback test. I doubt I got all the config registers set up correctly, but to double-check, I loaded Cypress's bulktest firmware (which copies everything from EP2OUT to EP2IN) and couldn't get that to work, either.
On the PC side, I am just running minicom on /dev/ttyUSB0. I provided debug=1 with the vendor=/product= options, and the debug logs show that usb-serial has found the two endpoints. (OK, I fudged a little, and used descriptors from another piece of firmware, since bulktest doesn't re-enumerate. But the endpoints are correct, as far as I can tell.) Also, I have confirmed that minicom works with a real Keyspan device on /dev/ttyUSB0 with a hardware loopback. Am I doing something fundamentally wrong here? I have tried this with both 2.6.0test1 and 2.4.20-18.9 (updated RH kernel). -- Charles Lepple <[EMAIL PROTECTED]> http://www.ghz.cc/charles/ ------------------------------------------------------- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.
