Other projects • Enumerate 10 CDC Serial over Raspberry Pi Pico 2

Hi

I have created a Raspberry Pi Pico 2 based device which can enumerate a 6 CDC Ports of Serial but i want to add 4 more CDC ports.

i have done the first 6 using this Github Repo https://github.com/8086net/pico-sexa-uart-bridge

now i Want Extra 4 Ports which i can commuicate as i will be needing it for a interface which has a 2 SPI Ports and 2 I2C ports.

If the pins are problem i will use the RP2350B Based board for extra pins

the problem is when i try to add more than 6 i get a device error in device manager STATUS_DEVICE_DATA_ERROR.

How do i fix this problem and kindly help me in it.

Thank you in advance
