Hm, that type2 device is the newer "HX" type device from prolific. I really don't know the differences in the different types, except for a patch someone from the company wrote to get the devices to work at all. Seems like there might be more to it than what we are currently doing. Care to try to contact prolific and ask them for specs on the devices so we can try to determine what is wrong? thanks, greg k-h ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
