USB flash card reader problem.

cferron · 03-20-2008, 10:48 AM

For some reason when I connect my USB compact Flash reader in any USB port I get this message from the kernel. It always reset the device!?!

Code:

reset high speed USB device using ehci_hcd and address 8
hub 3-0:1.0: port 4 disabled by hub (EMI?), re-enabling...

Then puts it back in the low speed configuration

Code:

usb 1-1: not running at top speed; connect to a high speed hub

Any idea what could cause that?

Thanks

as no better reply exists as yet....it may be your hardware or the kernel driver.

1) pls provide full details of the card reader......(b) search HCL to see if someone already has it working.

2) I run a vanilla kernel and once I know your hw...I or others will check to see if there is a new driver for it.

3) it may also be impacted on your udev and hal rules but lets look at the hw first?

What is HCL if I can ask before we start???
What is a Vanilla Kernel, does it taste good

?

Edit--> Ok, got my answer for the Vanilla Kernel... Well this is what I'm using, the latest from kernel.org. I guess that this is the Vanilla kernel...???

Thanks

ok please post the full make model etc of your reader.....

2) look at this page...there is box top RH cnr called main menu...click the HCL = hardware compatibility list...search your device in external storage

but still post your hw here pls even if your device is not listed.

Can't seem to find it... Here are the details...
===========================================
READER = CompuApps OmniFlash Uno CF 2.0! (USB2-UDMA40)
Controller: OnSpec xSil251-G
OM-U2-CFU4 / Part No.: CF06-11
Source: http://www.hjreggel.net/cardspeed/
===========================================

I have created this new rules for udev:

SYSFS{idVendor}=="55aa", SYSFS{idProduct}=="2b00", NAME="flashport1", MODE="0644", OPTIONS+="all_partitions"

It matches the reader vendor and idproduct (got those with lsusb command) and create the /dev/flashport entry with no problem when I connect the reader to any USB port. It seems to be stable and working for now, but it normally happend when I upload lots of card (35 and more in a day...)

UPDATE: I created a new rules files ex 55-myrules.rules in the /etc/udev/rules.d/ directory.... that seem to be causing a problem (lsusb was not giving any output + I was unable to mount my CF card, I wonder why?). I have put back my rules in the original 50-udev.rules and it seem to be working.

you have done better than me so I think you are almost there. My puny search of HCL was a zero.

2)
ok that link to readers also shows it PID 2B00

so going to controller gives us
xSil 251 (LQFP48) [PID 2B00] - CF/HDD Controller
PIO 0-6, MDMA 0-2, UDMA 0-4

I do not have your hw, but the info you have found and linked to should be enough to now make "persistent" rules

http://www.linuxjournal.com/article/7496

ahh well you have already tried that...but try again?

USB Card Reader

USB card readers (CompactFlash, SmartMedia, etc) are yet another range of USB storage devices which have different usage requirements.

These devices typically do not inform the host computer upon media change. So, if you plug in the device with no media, and then insert a card, the computer does not realise, and you do not have your mountable sdb1 partition node for the media.

One possible solution is to take advantage of the all_partitions option, which will create 16 partition nodes for every block device that the rule matches:
KERNEL="sd*", SUBSYSTEMS=="scsi", ATTRS{model}=="USB 2.0 CompactFlash Reader", SYMLINK+="cfrdr%n", OPTIONS+="all_partitions"
You will now have nodes named: cfrdr, cfrdr1, cfrdr2, cfrdr3, ..., cfrdr15.

Thanks for the time you put in that aus9, I really appreciate it!

Will try the above rule.

I'm just trying to understand what I'm doing here...

I have /dev entry created at every boot (/etc/rc.d/rc.local)
/bin/mknod /dev/sdb1 b 8 1
/bin/mknod /dev/sdc1 b 8 1
/bin/mknod /dev/sdd1 b 8 1
/bin/mknod /dev/sde1 b 8 1

Don't ask me why there is a 8 1 there, just don<t understand the minor or major number...

I have my /etc/fstab that has:
/dev/flashport1 /mnt/flash1 vfat user,ro,noatime,noauto 0 0

I have a udev rule that goes like this:
#Reader Uno2!
SYSFS{idVendor}=="55aa", SYSFS{idProduct}=="2b00", NAME="flashport1", MODE="0644"

Is that ok, or there are "cleaner" way to do what I<m doing right now.
How does linux know that /dev/sdb1 is related to /dev/flashport1????

Thanks again.
Claude, desperate to understand more

im just going to throw this in, and its not a solution at all, but i bought a bytestor card reader and got the same sort of error messages you have, i then bought a kingston card reader and it worked perfectly.

What is your problem, basically?

If it is that your device is not running at its full capable speed,
maybe you dont have usb 2.0 ports on your PC.
Your specs are reminescent of an old box.

I have 10 readers and they all did the same thing.... But since I change therules in udev, everything seem to be stable! I cross my finger, maybe my problem is solved? The reader I have is the faster on the market, speed is critical for us. As for machine spec, 100% certain they have USB2 (Dual quad core XEON) running ehci driver....

Keeping my fingers crossed too.
This discussion's too technical for me though.
