我的問題跟您類似，不知道您所謂的捉不到內建讀卡機是不是指"SD卡插入後沒反應"
我檢查硬體資訊(hwinfo)，發現有偵測到讀卡機

我覺得問題可能出在SD卡插進去之後的動作沒被正確處裡。
以下做了一點測試：
將SD插入內建讀卡機(ENE UB6225)
dmesg:
sd 2:0:0:0: [sdb] 7861248 512-byte hardware sectors (4025 MB)
sd 2:0:0:0: [sdb] Write Protect is off
sd 2:0:0:0: [sdb] Mode Sense: 03 00 00 00
sd 2:0:0:0: [sdb] Assuming drive cache: write through
mount -t vfat /dev/sdb/ /media/SD
dmesg:
FAT: bogus number of reserved sectors
VFS: Can't find a valid FAT filesystem on dev sdb.
將外接讀卡機插入USB插槽
dmesg:
usb 1-3: new high speed USB device using ehci_hcd and address 12
usb 1-3: configuration #1 chosen from 1 choice

將SD卡插入外接讀卡機
dmesg:
sd 8:0:0:0: [sdc] 7861248 512-byte hardware sectors (4025 MB)
sd 8:0:0:0: [sdc] Write Protect is off

P.S.當SD卡插到外接讀卡機的時是可以正常使用的。

目前內建讀卡機還是不能正常運作 ^^"....希望有人可以解決這個問題。
