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

However, the same driver works fine on BSP 4.14, so it seems that there may be a bug in the USB driver code for BSP 5.4. Could you help me fix the issue?
Solved! Go to Solution.
Thank you for your response. I modified the driver for xr21v1414., and now I can send and receive data successfully.I have attached the modified driver.
Hello,
Beware of this driver, it works okay when reading data with those errors, but my MX8MM died and rebooted randomly.
That's why I won't risk it and have unloaded the module, if not reading data.
You better try on 6.1v BSP:
Regards
hi:
Thank you for your reply. Do you have the xr21v1414 RS485 driver for bsp5.4.3 ?
