I/O errors with USB to IDE converter

[grahams1]

I/O errors when trying to access IDE disk via an USB to IDE converter (sold as R-Driver II).

Scanning with lsusb and lsscsi my system detects the device and a /dev/sda is created. However the disk partitions aren't seen and I can't mount it. A simple od </dev/sda fails with I/O errors, usually immediately but sometimes after reading a few disk blocks.
I also tried booting from a live ubuntu 6.06 cd and slax (2.6.16 kernel) and I see the same errors.

I've successfully accessed the same IDE disk via the converter on the same machine via windows XP and from DSL 3.2 (2.4.31 kernel) without issue.

From the website at http://www.usbgeek.com/prod_detail.php?prod_id=0190 the chipset is a MYSON CENTURY, CS88186

The lsusb -vv output is

Thanks for your bug report. To better help us troubleshoot the issue could add the output of 'fdisk -l /dev/sda' and 'dmesg' showing the I/O errors? Thanks in advance.

[grahams1 (gps1539)]

Thanks for looking into this. I will try to connect the device and get the fdisk and dmesg output in the next few days.

No output from fdisk -l /dev/sda

#fdisk -l /dev/sda

# fdisk /dev/sda

Unable to read /dev/sda

lsscsi shows the disk is connected

After a quick google search, it looks similar to this bug http://bugme.osdl.org/show_bug.cgi?id=3223

[Brian Murray (brian-murray)]

You mention using 6.06 and it not working, but I realized we don't what version of Ubuntu you are currently using. Once I have that information I can properly classify the bug. Also do you recall what specific kernel version was on the Knoppix CD that worked?

[grahams1 (gps1539)]

Hi

I'm currently on 6.10, but I get the same failure after booting a 6.06 live cd and I recently tried booting from a Feisty CD (downloaded ~ 1/26) and the issue is still there.

Sorry I had an error in my original post, I found DSL 3.2 (kernel 2.4.31), not Knoppix worked fine with this converter, as did Windoz XP.

[grahams1 (gps1539)]

Hi Brian

Any progress on this one?

It looks like an old bug reported and fixed? back in 04. http://bugme.osdl.org/show_bug.cgi?id=3223
That report talks about the patch being planned for submittal to 2.6.10. I'm wondering if that didn't happen.

I'd be happy to try the patch, but I'm not sure how to patch a Linux kernel. Are there any good howtos?

I can confirm that this bug is fixed in the 2.6.20-15 kernel
