Known problem, fixed with that patch that you sent to Linus last night
for the ub driver.

Right Pete?

I only had 2.6.23.12 working, and decided to try a newer kernel to see

But it still exists.

Yes. I was using ube1 before, must of had a typo when assembling this email.
I have retried just to be sure, and ube1 does not exist.

mount -t vfat /dev/ube1 /media/sd
mount: special device /dev/ube1 does not exist

That probably wouldn't help; it looks like he's using the ub driver, not
usb-storage.

Correct, the card readers are using the ub driver.

I'm not sure if it's the same issue (the sg table not initialized
before use). The tables are initialized to zero. Regretfuly I do
not understand how the new s/g API is supposed to be used (e.g.
if the last entry in the sg table special for chaining).

Created attachment 14776 [details]
ub fix for improper sg_init_table

Rich, please try the patch with sg_init_table(), see attached.

Hi Pete, I tried the patch, no luck.

Seems hal is not detecting when the memory card is inserted, like the other reader.   I did try making the node in dev,  mknod /dev/uba1 b 180 1 - when I try to mount, not a valid block device error occurs.

FAT: bogus number of reserved sectors
VFS: Can't find a valid FAT filesystem on dev uba.
mount: /dev/uba1 is not a valid block device

brw-r----- 1 root disk  180,  0 2008-02-11 00:57 "/dev/uba"
brw-r--r-- 1 root root  180,  1 2008-02-11 00:48 "/dev/uba1"


Is there a way to run ub in debug mode, since its not using usb_storage?



Thanks 
Rich

I guessed this would be something different, but since Greg asked in
comment #3, we had to test it.

By itself ub does not have any debugging at all, it relies on usbmon.
This way you do not need to rebuild anything for testing, because
usbmon usually is enabled. Please have a look at
Documentation/usb/usbmon.txt.

The test should be
1. stop HAL ("service haldaemon stop" on Fedora, or just kill hald)
2. Start cat /sys/kernel/debug/usbmon/0u > 00.mon
3. plug the device
4. watch dmesg to see that probing settled
   dmesg > 00.1.dmesg
5. cat /proc/partitions > 00.part   -- this will tell which device
   I presume that partitions are not detected at this point.
6. dd if=/dev/ube of=00.ube.img bs=1k count=1
   This either succeeds or returns "0+1 records", please save
   the terminal log
7. dmesg > 00.2.dmesg
8. Kill the cat from step 2
9. cat /proc/bus/usb/devices > 00.devices
   Not strictly required, but I'm curious what we're dealing with.
   Also it makes it easier to read usbmon traces.

Please attach the 00.* files to the bug.

I didn't see any activity when I inserted the memory card (tried a few times).
I did reconnect the device, so you may see the disconnect and then a few seconds later a second connect.

I recompiled the kernel with the debugfs enabled.
I was able to capture some output from usbmon,

I considered, and I cannot guess what it is, and it would take too
much work to figure it out.

Why don't you disable CONFIG_BLK_DEV_UB and hope for the best?

Hi

Before giving up, I did another search on the net, and came across a note about libusual.  I doubled checked my system and found in the config, libusual was not enabled.  I enabled it and rebooted - Bingo!

Both card readers changed back to /dev/sd* devices. When I added the memory card, the partition appeared and I was able to mount both cards, first the SD, and then the SDHC.  

Thanks for taking the time to take a look at this.
The device is connecting fine now.

Let's close this, then. I'd like to see how is it that partitions are
not detected on ub, but it works fine on my systems.
