USB Card Reader problem

I have an all-in-one USB card reader in one of my 3 1/2" bays on my computer. It worked fine under 2.6.9-1.667, but now under 2.6.11-1.27_FC3 I'm having a big problem.

To put it simply, it keeps resetting itself. The green power light on the card reader stays on for about 5 seconds, then flickers before staying on for another 5 seconds. This leaves my /var/log/messages looking something like this:

Code:

[michael@rei ~]$ tail /var/log/messages

Which REALLY slows down applications such as Audio and Video players.

after typing /sbin/lsusb, I find the device I need:

Code:

Bus 004 Device 008: ID 10df:0100 In-Win Development, Inc.

I'll try and put up the manufacturer and model of the reader first, but since it keeps resetting I can't do it under Linux so I'll need to reboot to window$. Any help will be greatly appreciated.

Edit The card reader in question is the In-Win iApp 6-in-1. I've found a previous thread about this card reader, but it's been archived and there was no replies to it.

What happens when you try this as root?

mount /dev/sda1 /mnt/usb -t vfat

Just curious. I have a generic multicard USB reader. The slots are recognized as sdb,sdc,sdd. (sda is my harddrive)

It says that the device doesn't exist

Code:

[root@rei michael]# mount /dev/sda1 /media/usb1 -t vfat

mount: special device /dev/sda1 does not exist

Look under /dev. Is there an sda? if not, try
/dev/MAKEDEV -v sda1

Stll doesn't work

Code:

[root@rei dev]# /dev/MAKEDEV -v sda1

create sda1                          b  8  1 root:disk 640 system_u:object_r:fixed_disk_device_t

create sda10                          b  8  10 root:disk 640 system_u:object_r:fixed_disk_device_t

create sda11                          b  8  11 root:disk 640 system_u:object_r:fixed_disk_device_t

create sda12                          b  8  12 root:disk 640 system_u:object_r:fixed_disk_device_t

create sda13                          b  8  13 root:disk 640 system_u:object_r:fixed_disk_device_t

create sda14                          b  8  14 root:disk 640 system_u:object_r:fixed_disk_device_t

create sda15                          b  8  15 root:disk 640 system_u:object_r:fixed_disk_device_t

[root@rei dev]# mount /dev/sda1 /media/usb1 -t vfat

mount: special device /dev/sda1 does not exist

Do you have a card plugged into the first slot on the card reader? Mount only works when a card is plugged in.

if its the 2d or 3d slot, you'll have to create sdb and sdc.

I don't have a card to test unfortunately. However, that's beside the point. It's the card reader itself that keeps resetting itself every 3 seconds, so I don't think the card will have chance to mount. I just need to stop the reader from resetting itself every few seconds since it's really making my system sluggy.

I'd unplug it altogther. I had a built in card reader on an Asus machine that just died one day. Two warranties to the company later, it still doesn't work. For about $20 USD you can get a USB one that will work just fine.

Hi,

Had the same device and same trouble.

It appears that, when unplugged, then re-plugged, while the computer is running, it works good.
