A friend of mine has a tc-08 RS232. We installed the software correctly, but anyway the rs232-module won't be recongnized by the device manager of windows xp. therefore, she cannot use it with the logging software "picolog".
she is using the rs232-device with a serial to usb adaptor. i do know, that you are selling your own serial to usb adaptors, but i don't think her problem could be related to a wrong converter, since the device itself is registered by windows, only the driver does not seem to be installed correctly due to the driver somehow not being present, although we installed to software correctly.
she has already tried to run her configuration on a different PC with the same result - so success. addtionally, we exchanged the rs232 cable, but still the problem perists.
i counter checked the date of the file tc0832.dll since i read this thread:
still, everything seemed ok.
do you have any hint, what could be wrong? i am running out of luck on this one slowly...
