wireless usb driver err

hello, ti's engineer,

Recently I am using the armv7 cpu under the arm platform, it is ti’s am4378, i am using the sdk of ti, linux4.19, when I transplant the wireless usb host driver, realtek rtl8192cu, the following error has occurred, has been checked for a long time, no clue, can tell me should From what aspects to locate this error, or can you give me the firmware documentation for rtl8192cu, thank you,

The specific kernel log is as follows:

Annie Liu：

kernel log似乎表明wifi驱动程序rtl8xxxu无法初始化wifi加密狗。 很抱歉，我们没有内部加密狗和wifi驱动程序的信息，这超出了我们的支持范围。建议您联系wifi加密狗供应商获取支持。

不是这个问题,我已经配置完成了,只是驱动不能对wifi模块进行初始化
