[問題 - 已解決] digital camera 會 mount 失敗 : medium not found

[wsun013]

我在 kernel 2.6.9,用 Panasonic DMC-F1 (SD 卡 ) 有問題喔~

這示我的 dmesg :

usb 1-1: new full speed USB device using address 3

應該在 /dev/sda 底下
可是dmesg 接著:

devfs_mk_dev: could not append to parent for scsi/host0/bus0/target0/lun0/part1

然後我try :
#mount /dev/sda /usb
mount: No medium found

#mount /dev/sda0 /usb
mount: special device /dev/sda0 does not exist

#mount /dev/sd1 /usb
mount: No medium found

到10 都沒有...

所以我題問 :
devfs 是否與此有關? 可否取消? 如何取消呢?

用 woody 的 kernel 2.4 可以mount 的到
kernel_image-2.6.9 裝的就不行!?
嗯.......
再試!

試試看換個 driver，比如說不要用 ehci_hcd，改用 ohci-hcd

這是類似的解決方法

http://www.spinics.net/lists/usb/msg02260.html

Step 1:
從dmesg 找出
usb-storage: waiting for device to settle before scanning
Vendor: MATSHITA Model: DMC-F1 Rev: 0100
Type: Direct-Access ANSI SCSI revision: 02

Step 2:
編輯 /proc/scsi/device_info
找出跟你類似的 camera or sd card reader/sd card
我的是 MATSHITA DMC 系列, 0x80400 不管是啥賽, 記了再說!

Step 3:
echo 'MATSHITA:DMC-F1:0x80400' > /proc/scsi/device_info

再把camera 接上
就可以mount 了..
看來medium 的種類竟然是在look-up-table 裡.....
