I have a VM110 board with which I am able to communicate very well with a PC.
What I really would like to do is communicate via the USB from a industrial MMI (man machine interface) a Weintek 8070i, in this MMI I can write macros to communicate in ASCII of Hex via the USB port.
Can you let me know if it is possible and where I can find some documentation to know which commands to use to access registers in the VM110
Best Regards
David
You’ll find some info in these threads:

You’ll find the VID and PIDs of the K8055(N) cards in this thread:

what is the baud rate and data format?
Best Regards

USB does not have a baud rate (although somewhat related, baud rate and bit rate are two different things and should not be confused).
Anyhow, the VM110/K8055 use Low Speed USB (1.5 Mbit/s) while the VM110N/K8055N use Full Speed (12 Mbit/s).
The data format is an 8 byte HID packet in both directions as described in one of the previously linked posts.
