Some more details, I've tried this on a Acer TravelMate 8200 and Dell XPS Laptops, running the same kernel versions and both give the same problems.
I've also discovered if I force unload the usbserial module and then plug the dongle back in the gdbproxy initialises the dongle correctly, but you have to unplug and unload the ti_usb_3410_5052 and usbserial modules between each run, which is a bit of a pain. This definitely seems like a bug in the usbserial subsystem in 2.6.28. I'm looking at the differences between the two versions of `drivers/usb/serial/usb-serial.c` now. Still if anyone has ideas, they will be most welcome. -- Regards, Stewart Allen [email protected] On Saturday 07 March 2009 11:08:18 Mark Lister wrote: > try > > echo "2" > /sys/bus/usb/devices/2-1.1/bConfigurationValue > > change the path to match your system > > Needs a Wiki entry... > > Stewart Allen wrote: > > Hi all, > > > > This is the problems I having... > > > > The usb dongle gets picked up by linux and the /dev/ttyUSB0 gets created. > > I can start the msp430-gdbproxy and even connect and debug.
