只找到了一个英文的介绍资料,大家凑合看看,反正主要参数看懂就行了
AU6368
USB 2.0 Multiple Slots Flash Memory Card Reader The AU6368 is an integrated single chip memory card reader controller specially designed for notebook, hand-held and other PC peripheral devices, which require fewer components for small PCB area. It supports a widely used flash memory card such as CF, MD, SMC, xD Picture Card, MS, MS Pro, MS Duo, SD and MMC.

读卡器电路板正面:
主要由AU6368主控、USB插孔、12M晶振、指示灯、稳压IC、卡插槽、帖片元件等组成
1、一般比较常见的故障就是USB插孔损坏,用观察法直接更换即可
2、12M晶振坏,和U盘的维修方法差不多,用代换法很容易排除
3、3脚稳压IC,主要是将USB的5V电压转换为3.3V给主控芯片供电
4、还有各插槽也容易损坏,一般外观就可以看出来,而且对其它插槽使用没有影响
读卡器背面:
没什么好说的,主要故障点就是CF卡插槽的插针容易拆弯,拆开校正即可
附上AU6368的低格程序和驱动下载,呵呵,这可是好东西
