Bug 33981 – USB cardreader not working under gentoo-sources; works under 2.4.22 vanilla-sources

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description macmasta 2003-11-20 19:14:21 UTC]

So, I have a USB media reader. When plugged into my laptop (2.4.22-vanilla) it
works perfectly; hotplug picks it up and emulates scsi, and all is well.

When I plug the same device into my desktop, the logs see that it was attached,
but it never appears in devfs.

Reproducible: Always
Steps to Reproduce:
1.Plug device in. 
2. Notice that it works or doesn't work.
3. Hmmm...



Expected Results:  
Recognized the device and added it to devfs so I can access the device.

Can you try with gentoo-test-sources? I'm pushing for that to move to gentoo-sources soon.

Yeah, 2.4.22 vanilla obviously has support for such things, but I'll see whether this is backportable.

1) I don't see the revelant log portions for the non-working kernel, can you attach relevant portions for both kernels?

2) Can you also attach /proc/config from each kernel? Thanks...

in)

I don't have /proc/config on either machine; would you like /usr/src/linux/.config?

I should note that the laptop (working machine) has been able to access this device since 2.4.20-vanilla.

[Comment 8 macmasta 2003-11-22 16:34:22 UTC]

Tim Yamin sent me an e-mail; I'm reproducing it here, with my answers, to keep everything in one place.

That's not it, although it may run on the same chipset. Mine bills itself as a 'ZiO!' somethingorother.


>Yes, I did mean the /usr/src/linux-.../.config; sometimes kernels have >/proc/config and that is more accurate incase something got modified and out of >sync with the file .config. Attach the ".config" files for both kernels, if you >may, please.

Done.

[Comment 11 macmasta 2003-11-22 16:37:12 UTC]

It would appear that I mis-spoke earlier; it seems the working machine is running 2.4.21, not .22.

[Comment 12 Tim Yamin (RETIRED) 2003-11-23 03:11:17 UTC]

Can you please enable CONFIG_USB_DEBUG on the faulty kernel and see if anything useful comes out... Also try CONFIG_USB_STORAGE_DPCM. Thanks.

[Comment 13 macmasta 2003-12-13 15:20:10 UTC]

So, rebuilt the desktop machine's kernel with genkernel yesterday...and it works now.

gentoo-sources-2.4.20-r9.

May as well close this.

[Comment 14 Tim Yamin (RETIRED) 2003-12-13 15:33:26 UTC]

Closing as this seems to be resolved.
