Re: [Gpsbabel-misc] GPS 60CS problem

I did spend a little time delving into the source before I joined the list and sent a request for help - and you are spot on the mark - I'd taken an approach of putting in some fprintf statements around the place until i worked out the function call - and you're absolutely right: usb_interrupt_read. I later spotted the commented-out debug line and that produced way more output. Anyways - problems solved with updated firmware. I'm a muppet for not doing that - apologies! If I can help the project in any way, just let me know!
