If you disable the driver that supports this hardware, does the message go away? The driver controlling this is a "staging" driver and is of dubious quality, so you might wish to disable it unless you need to use the hardware. Do you need to use it? Yes, I need it. And I used it without any problems on at least .36 kernel series. How? With what kernel driver? Can you provide the output of 'lsusb -v' attached to this bug with both the .36 and .37 kernels? Also, a full kernel log attached to this bug for .37 would be great to have to see what is really going on here. Created attachment 45982 [details]

dmesg 2.6.37
Another note: this messages appears only if attached cardreader is empty. If card is inserted this messages disappear and device is functional. So it seems that the problem is annoying messages only. Created attachment 46032 [details]
kernel.log output when MicroSD is inserted
kernel.log output, starting when MicroSD adapter is inserted and ending when the adapter is remeved from the reader. On an Asus EeePC.

lsusb -v output
Issuing auto-REQUEST_SENSE I have the ^ same output in kernel.log - I'm also using ArchLinux, kernel 2.6.37. For me, the message only persists when the card-reader has an SD inserted into it. So far, I've only tried this with an SD adapter (for micro SD's to be inserted into), and I don't have a micro SD to insert - so this may also be an "empty" case. However, when I remove the SD-sized adapter from the reader, the messages stop. I attached the kernel.log output, starting when I insert the adapter and ending when I remove the adapter. lsusb output also attached. Fixed in my case in 37.1 Hello, same issue here since 2.6.37, had no idea what this meant until reading your issue with the card reader... i have one built into my computer (cannot unplug it), i have never used it either. See attachment kernel.log See attachment lsusb -v -s004 Created attachment 49182 [details]

dmesg
Inserting a blank SD card into my reader, and mounting it, stops spamming the logs with "Issuing auto-REQUEST_SENSE".
Attached output of dmesg when a device is mounted from the card reader. And then unmounted a few seconds later.
Build kernel commented out this option zcat /proc/config.gz | grep USB_ENE # CONFIG_USB_ENESTORAGE is not set No more spamming Solved |
