Other Parts Discussed in Thread: EK-TM4C123GXL, EK-TM4C1294XL
Hello,
I built my own TM4C123G6PM board and it seems the USB hardware isn't functioning properly for some reason, I tried the "usb_dev_serial" and "usb_dev_bulk" examples for EK-TM4C123GXL board from the Tivware, first when I plug the USB to the machine it's not recognized right away (my guess is something went wrong in the enumeration process), then after 30 seconds or so I get the Windows message "USB device not recognized". Did anyone face a similar problem with the same microcontroller?.
Running the same examples on it's bigger sister (TM4C1294 Tiva C Connected Launchpad) works well without any issues.
I have attached the schematic of the TM4C123G I'm using, along with a screenshot of the error. The OS I'm using is Windows 10.
