Part Number: INA220
I'm facing a USB communication problem shows below on customer side. I can find USB device on computer and have 3 LED turned on but connect DIG board. Another thing I found is that I can connect the board on my computer but my costomer can't. We tried serveral computers and reinstalled the software but the issue still there. I also tried other solutions mentioned in other blogs in this forum.
Do you have any suggestion for me to fix this issue.
In reply to Peter Iliya:
The user manual also says this:
Figure 11 shows an error that pops up if the computer cannot communicate with the EVM. If you receivethis error, first check to see that the USB cable is properly connected. This error can also occur if youconnect the USB cable before the USB DIG Platform 9V power source. A second possible reason for thisproblem is that there may be a problem with your computer USB Human Interface Device Driver. Makesure that when you plug the in the USB cable, the computer recognizes the device. If the sound is on, youwill hear the distinctive sound that you expect when a USB device is properly connected to the PC.
This was developed on an earlier windows OS, and while we haven't heard of any compatibility problems (it uses the same HID driver as keyboards and mice), perhaps you are seeing something like that happening. I personally haven't tried the EVM on anything over windows 7.

Thanks for reply.
I can find the USB device and HID on devce manager from computer control panel. And customer's operation system is Windows 7.
But still can't connect the DIG through software, and once I change to connect my own computer(windows 10), run software as administrator both software and board work well.
