每次开机在这里要卡住一分多钟,dmesg:

真是让人不能自理……
笔记本内置读卡器出现硬件问题,Win系统下有未识别设备,谷歌发现解决方案大多是移除设备,但是我这读卡器是焊在主板上的。
前面还有一个error -22,但是似乎并没有太大影响,可以顺利识别:
---------
[ 2.564532] usb 2-1.4: string descriptor 0 read error: -22
[ 2.565653] usb 2-1.4: New USB device found, idVendor=0cf3, idProduct=3004
[ 2.565657] usb 2-1.4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
---------
请教各位要如何处理,搜索半晚上感觉毫无收获,头晕脑胀,错误代码意义都没有搜出个意思……
