I have a SWEEX usb to serial adaptor:
I installed these drivers on my Mac OS X Lion (10.7.5): http://sourceforge.net/projects/osx-pl2303/
I tried to connect with the Mac software I found here: https://github.com/adafruit/SpokePOV but I'm unable to connect. If I increase the delay to 10,000: it connects but I'm unable to read out the banks.
If I connect it to Windows using the official drivers for my SWEEX serial port, it connects and retrieves the banks perfectly!
I guess something's wrong with the Mac usb driver.
Does anyone have the same problem or has a solution?
