What error do you get?

If its the "device descriptor read failed" code, its because you swapped the D+ and D- data lines in your schematic.

Hello,

It looks like schematics needs to be finished first. You have to follow the design to make it for hardware supported; data lines, DECUSB and VBUS. For example this is from our schematic.

I am using ncs. I am using LDO voltage regulator from maxim's MAX 20353 PMIC to power my MCU. I haven't configured my clock yet.

Hello,

Are you working on nRF5SDk or NCS? How have you powered the custom board? How is the clock configured?

Actually I havent configured anything. I just connected 4 pins: USB,D+,D- and GND from my charging port to MCU. It works normally for nrf 5340 DK, so I thought that much configuration would be enough for USB. I would really appreciate if you would guide me for this.

Hello Barsha,

How have you configured the VBUS pin? What is the resistance value? Can you please share the config file?

Thanks.
