#142393 - AT89C5131 USB troubles |
Hi,
I'm currently using Amtel AT89C5131. I'm having trouble with the USB connector. Whenever I plug in the USB cable the FLIP software will show "Cannot open port". Vendor ID=ffff and Product ID=ffff show on the Driver Wizard. USB name under "Unknown device". Please give some advice. Is there any problem with the hardware or others? |
