I'm using the CDC usb host driver and a Microchip MCP2200 usb to serial chip. Receiving doesn't return all the data.

But when I put a loopback on the cable and transmit 256 chars and loop it back, only 96 chars come back.
has anyone seend any issues with receiving chars with the USB CDC driver ?

Hi

I would suggest you try to loopback your PC and MCP2200 to see whether this issue still happens.
