Hi:
I recently ported the USB to serial driver for the XR21V1414 driver to the 8mm platform. I’m using BSP 5.4.3, but I keep encountering the following error when reading data, which is causing the read and write functions to malfunction.[ 1195.875954] cdc_xr_usb_serial 1-1.3:1.5: xr_usb_serial_read_bulk_callback - non-zero urb status: -2
