Comment 7 for bug 366478

I am running karmic with kernel 2.6.31-14-generic and I confirm this bug with the all-in-one SD-card-reader of my Samsung E152 notebook. Here is the output of lsusb, I will attach the verbose output too:

Bus 001 Device 005: ID 058f:6366 Alcor Micro Corp.

when I insert a SD-card, dmesg tells me this:

[ 2777.822565] usb 1-5: new high speed USB device using ehci_hcd and address 6
[ 2777.974865] usb 1-5: configuration #1 chosen from 1 choice

but the strange thing is that the device /dev/sdb1 isn't created at all:

>$ ls /dev/sd*
/dev/sda /dev/sda1 /dev/sda2 /dev/sda3 /dev/sda4 /dev/sda5 /dev/sda6 /dev/sda7 /dev/sda8

after waiting for a while, dmesg periodically throws out this message in a loop:

[ 2814.130066] usb 1-5: reset high speed USB device using ehci_hcd and address 6

then, after several minutes, I get this messages:

I tested it with the latest knoppix, same problem... The card reader works flawlessly with Vista... I hope there will be a solution for Linux soon, I don't like having to boot Vista every time I want to access the pictures of my digicam :( Maybe this bug should be forwarded to bugzilla.kernel.org ? If more infos about my system are needed, I will be glad to provide them, or help fixing this bug in any way...
