I have been using an ADC212 with usb to parallel convertor for some time with no problem when I connect to the USB to parallel convertor direct to the PC via usb cable. I have latest picoscope code and drivers and the software is running on windows XP.
I have recently been trying to run the ADC212/usb to parallel port convertor through a small "Trust" USB hub. This hub provides 4 usb ports. It can be powered from an external 5V supply or powered from PC USB.
When the hub is used, the communication with the ADC212 is erratic. It seems to work for a while but after using for a while, the windows application just hangs up whilst acquiring data from the ADC212. This happens whether the hub has external power or not.
The hub is cheap and is obviously the problem. I was just wondering if anyone could recommend a suitable 4 port hub that is known to work or if anyone from Pico can give guidance on what are the important specifications to look for when buying a hub for use with the USB to parallel port convertor.
Thanks in advance.
