SDcard对ENE闪存UB6250读卡器的支持(见于宏碁Aspire One 522)
SDcard对ENE闪存UB6250读卡器的支持(见于宏碁Aspire One 522)
提问于 2012-09-08 17:53:27
我有一台宏碁Aspire One 522上网本，我想让SDcard阅读器工作，但我很难让它在插入SDcard后识别出来。
我使用Slackware并始终编译自己的内核，因此我已经启用了Device Drivers->MMC/SD/SDIO card support选项和相应的内核模块，编译并正确安装了内核及其模块(内核版本为3.5.3)。
卡读取器似乎一插入SDcard就连接到USB总线，因为lsusb只在此事件之后显示阅读器：
Bus 002 Device 005: ID 0cf2:6250 ENE Technology, Inc. SD card reader (UB6250)通常情况下，在插入卡后，我会看到像/dev/mmcblk0和卡分区(/dev/mmcblk0p1、/dev/mmcblk0p2等)这样的块设备，但是什么也没有出现。在插入卡时监视/var/log/消息显示如下：

Sep 8 14:43:44 aspire mtp-probe: bus: 2, device: 6 was not an MTP device显示读取器连接到USB总线，但没有检测到块设备。有人对此有任何暗示吗？我是不是错过了一些东西，或者对这个读者的支持还没有完全发挥作用？谢谢!

在对通用Slackware内核重新启动之后，我注意到SDcard被检测为SCSI设备- dmesg输出，如下所示：
