USB-CTR timer status readback

usb-ctr.c contains this:

void usbTimerControlR_USB_CTR(libusb_device_handle *udev, uint8_t timer,  uint8_t *control)
{
  /*
    This command reads/writes the timer control register
    control:   bit 0:    1 = enable timer,  0 = disable timer
               bit 1:    1 = timer running, 0 = timer stopped
                        (read only, useful when using count)
               bit 2:    1 = inverted output (active low)
                         0 = normal output (active high)
               bits 3-7: reserved

I have tested using this function to read the status in bit 1. However, it does not work, control always returns 0 even if the timer is running.

Have you tested this?

If it works for you then perhaps I need new firmware? What firmware are you using?

I'm using firmware version 00.46, and I'm getting 0x0 also. The device is returning a byte, so that
part is working. I sent and email to MCC to see if they can help.

I have looked hard and their UL library API provides no way to read the information. I was excited when I saw that the Linux API seemed to support it. Even if they make new firmware that does it, they will need to add it to their UL API.

Did you get any response from MCC about this issue?

MCC is looking into this issue. I will keep this open until resolved.
